The present disclosure relates to the field of three-dimensional (3D) printing technologies, and in particular, to 3D printing design, printing, and licensing methods, apparatuses, and systems.
Different from two-dimensional text printing on a paper and a conventional manner in which a product is manufactured by means of milling or the like, 3D printing is a series of technologies and methods in which an article is manufactured by means of three-dimensional layer-by-layer printing. A specific implementation manner is a computer three-dimensional design model is used as a blueprint, and special materials such as metal powder, ceramic powder, plastic, and cell tissue are accumulated and bonded layer by layer by software hierarchical discretization and numerical control molding systems using a laser beam, a hot melt nozzle, or the like, and are finally superposed to form a shape and manufacture a physical product.
Compared with a conventional manufacturing method, the 3D printing has many advantages. For example, a technological process is simplified, an article whose spatial shape is relatively complex can be manufactured, and raw materials are reduced. Therefore, in recent years, a 3D printing technology develops quickly, and is applied in many fields, for example, commodities, food, chemical engineering, automobile, medical supplies . . . . Articles manufactured by means of the 3D printing already get deep into various fields of people's lives.
For some articles such as a gun and a knife, if they are put into mass production and freely circulated in society, social stability and personal safety of citizens are greatly threatened. Therefore, these high-danger articles need to be regulated. In a conventional method, these high-danger articles are all manufactured and produced in a mold or machine tool by means of casting, forging, milling, or carving. Therefore, these high-danger articles can be regulated by controlling a circulation way of the mold or machine tool for producing these high-danger articles. However, in the 3D printing technology, a product can be manufactured by means of only design by a computer and printing by a printer, and no other tools is required. Therefore, it is very difficult to regulate a high-danger article produced by means of the 3D printing, and social stability and personal safety of citizens are affected.
Embodiments of the present disclosure provide 3D printing design, printing, and licensing methods, apparatuses, and systems, which can implement regulation on a target product, resolve a problem of difficulty to regulate production of a high-danger article, and ensure social stability and personal safety of citizens.

According to this method, determining by the 3D printing system on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens.
Embodiments of the present disclosure provide a 3D printing design method, so as to implement regulation on a target product. The embodiments of the present disclosure further provide a 3D printing method, a 3D printing licensing method, and related apparatuses and systems. Descriptions are provided below separately.
Referring to
When production is performed using a 3D printing technology, a user first needs to design a target print file using a 3D printing design system. There are many methods for designing the target print file. For example, design is performed by means of computer modeling. No limitation is set thereto in this embodiment of the present disclosure. The 3D printing design system determines the target print file.
The target print file is a form of data that records a characteristic of a manufactured target, and a format of the target print file is not limited in this embodiment of the present disclosure.
After determining the target print file, the 3D printing design system determines whether the target print file meets the first safety criterion. There are many methods for the 3D printing design system to determine whether the target print file meets the first safety criterion, which are described in detail in subsequent embodiments, and no limitation is set thereto in this embodiment.
In a 3D printing technology at a current stage, after completing designing a target print file, a 3D printing design system needs to send the designed target print file to a 3D printing system for printing. Therefore, in this embodiment, if the 3D printing design system determines that the target print file meets the first safety criterion, the 3D printing design system sends the target print file to the 3D printing system, so that the 3D printing system performs printing according to the target print file.
The 3D printing design system may send the target print file to the 3D printing system through the Internet, or may send the target print file to the 3D printing system using an independent data channel between the 3D printing design system and the 3D printing system, or may send the target print file to the 3D printing system by copying data using a magnetic disk, or may send the target print file to the 3D printing system using another method, which is not limited in this embodiment of the present disclosure.
If the 3D printing design system determines that the target print file does not meet the first safety criterion, the 3D printing design system may not send the target print file to the 3D printing system, or may process the target print file and then send the target print file to the 3D printing system, or another method may be used, which is specifically described in detail in subsequent embodiments, and no limitation is set thereto in this embodiment.
In this embodiment, after completing designing a target print file, a 3D printing design system determines whether the target print file meets a first safety criterion, and if the target print file meets the first safety criterion, sends the target print file to a 3D printing system, so that the 3D printing system performs printing according to the target print file. By determining whether the target print file meets the first safety criterion, determining by the 3D printing design system on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens.
In the embodiment shown in
Step 201 is basically the same as step 101, and details are not described herein again.
Each target print file designed by the 3D printing design system corresponds to a target product. For example, if the 3D printing design system designs a target print file about an automobile, a target product corresponding to the target print file is an automobile. In addition, the target product has an attribute, where the attribute may be: category information of a raw material of the target product, precision information of the raw material of the target product, manufacturing technological process information of the target product, spatial shape information of the target product, or purpose information of the target product, or may be an attribute in another aspect, which is not limited herein.
In this embodiment, the 3D printing design system acquires the attribute of the target product corresponding to the target print file.
After acquiring the attribute of the target product corresponding to the target print file, the 3D printing design system may acquire, according to the attribute of the target product, a class of the target product corresponding to the target print file, where the class of the target product is used to indicate a classification of the target print file.
There are many criterions for acquiring, according to the attribute of the target product, the class of the target product corresponding to the target print file. For example, the class of the target product is determined according to a category, in the attribute of the target product, of the raw material of the target product, and if the category of the raw material of the target product is iron, the class of the target product is metal product; or if the category of the raw material of the target product is polyethylene, the class of the target product is plastic product. Alternatively, the class of the target product is determined according to a purpose, in the attribute of the target product, of the target product, and if the purpose of the target product is walk replacement, the class of the target product is vehicle; or if the purpose of the target product is containing liquid, the class of the target product is container. The 3D printing design system may also acquire, according to another attribute of the target product, the class of the target product corresponding to the target print file, or may acquire, according to attributes of the target product in multiple aspects, the class of the target product corresponding to the target print file. No limitation is set thereto herein.
The class of the target product may also simply include safe product and non-safe product. For example, if the 3D printing design system learns from the attribute of the target product that the raw material of the target product includes a prohibited raw material, or a spatial shape of the target product is a shape of a prohibited article such as a weapon, or a manufacturing technological process of the target product relates to a technological process of a prohibited article, or the target product is used in a behavior activity that may harm life and property safety of citizens, the 3D printing design system determines that the class of the target product is non-safe product. The 3D printing design system may also determine, according to an attribute of the target product in another aspect, whether the class of the target product is non-safe product or safe product. No limitation is set thereto herein.
After acquiring the class of the target product corresponding to the target print file, the 3D printing design system may further determine whether the target print file meets a first safety criterion. There is a correspondence between the product class and the first safety criterion. For example, a metal product corresponds to meeting the first safety criterion, and a plastic product corresponds to not meeting the first safety criterion.
There are many methods for acquiring the correspondence between the product class and the first safety criterion, where the correspondence may be manually set, or may be actively acquired by the 3D printing design system from a server, or may be passively received by the 3D printing design system from a server, or another manner may be used. No limitation is set thereto herein. The 3D printing design system determines, according to the correspondence between the product class and the first safety criterion, whether the target print file corresponding to the class of the target product meets the first safety criterion.
Particularly, if in step 203, the product class includes only safe product and non-safe product, the determining, by the 3D printing design system according to a correspondence between the product class and a first safety criterion, whether the target print file meets the first safety criterion includes: if the class of the target product is safe product, determining, by the 3D printing design system, that the target print file meets the first safety criterion, or if the class of the target product is non-safe product, determining, by the 3D printing design system, that the target print file does not meet the first safety criterion.
If the 3D printing design system determines that the target print file meets the first safety criterion, step 205 is performed.
If the 3D printing design system determines that the target print file does not meet the first safety criterion, step 206 is performed.
If the 3D printing design system determines that the target print file meets the first safety criterion, the 3D printing design system sends the target print file to a 3D printing system, so that the 3D printing system performs printing according to the target print file.
The executing, by the 3D printing design system, another operation if the 3D printing design system determines that the target print file does not meet the first safety criterion includes skipping, by the 3D printing design system, sending the target print file to the 3D printing system, or processing, by the 3D printing design system, the target print file and then sending the target print file to the 3D printing system, or may be another operation, which is specifically described in detail in subsequent embodiments, and no limitation is set thereto in this embodiment.
To prevent information such as the target print file from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between the 3D printing design system and the 3D printing system.
In this embodiment, how a 3D printing design system determines whether a target print file meets a first safety criterion is detailed based on the embodiment shown in
In the embodiment shown in
Steps 301 to 304 are basically the same as steps 201 to 204, and details are not described herein again.
If in step 304, the 3D printing design system determines that the target print file meets the first safety criterion, step 307 is performed; or if the 3D printing design system determines that the target print file does not meet the first safety criterion, step 305 is performed.
If the 3D printing design system determines that the target print file does not meet the first safety criterion, the 3D printing design system sends first license request information to a printing licensing center.
The printing licensing center is configured to determine whether the request information received by the printing licensing center meets a particular safety criterion, and if yes, issue a printing license corresponding to the file, where the printing license indicates that a 3D printing system is allowed to perform printing according to the target print file.
A perfect 3D printing system may include more than one printing licensing center. The 3D printing design system may search for a corresponding printing licensing center according to the target print file.
The first license request information is used to request the printing licensing center for a printing license, where the first license request information may include the target print file, or the attribute of the target product, or the class of the target product, or may be other information, which is not limited herein.
After the 3D printing design system sends the first license request information to the printing licensing center, the printing licensing center determines whether the first license request information meets a second safety criterion, and if yes, sends a first printing license to the 3D printing design system. The 3D printing design system determines whether the first printing license sent by the licensing center is received. The second safety criterion is a criterion for the licensing center to determine whether a print file corresponding to the received request information is safe.
If the 3D printing design system determines that the first printing license sent by the licensing center is received, it indicates that the printing licensing center determines that the first license request information meets the second safety criterion, and step 307 is performed.
If the 3D printing design system determines that the first printing license sent by the licensing center is not received, it indicates that the printing licensing center determines that the first license request information does not meet the second safety criterion, and step 308 is performed.
If the 3D printing design system determines that the target print file meets the first safety criterion, or determines that the first printing license sent by the licensing center is received, the 3D printing design system sends the target print file to a 3D printing system, so that the 3D printing system performs printing according to the target print file.
The executing, by the 3D printing design system, another operation if the 3D printing design system determines that the target print file does not meet the first safety criterion and the 3D printing design system determines that the first printing license sent by the licensing center is not received includes skipping, by the 3D printing design system, the target print file to the 3D printing system, or processing, by the 3D printing design system, the target print file and then sending the target print file to the 3D printing system, or may be another operation, which is not limited in this embodiment.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between the 3D printing design system, the printing licensing center, and the 3D printing system.
In this embodiment, how a 3D printing design system specifically performs another operation when the 3D printing design system determines that a target print file does not meet a first safety criterion is explained in detail. If the 3D printing design system determines that the target print file does not meet the first safety criterion, the 3D printing design system sends first license request information to a printing licensing center, and then determines whether a first printing license sent by the licensing center is received. If the 3D printing design system determines that the first printing license sent by the licensing center is received, it indicates that the printing licensing center determines that the first license request information meets a second safety criterion, and the 3D printing design system sends the target print file to a 3D printing system, so that the 3D printing system performs printing according to the target print file. According to this method provided in this embodiment, quadratic determining by the 3D printing design system and the printing licensing center on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens.
In the embodiment shown in
A licensing center needs to receive license requests sent by one or more 3D printing design systems, and therefore the amount of data received by the licensing center is huge, and processing of relatively much data causes many problems such as low efficiency of the licensing center and excessively heavy load of a server. Therefore, the licensing center may send a pre-determined printing license to a 3D printing design system, where the pre-determined printing license corresponds to a target print file of a preset category, and may specifically correspond to a target print file having an attribute of a target product. For example, if the pre-determined printing license corresponds to a target print file a category of a raw material of a target product of which is plastic, all target print files categories of raw materials of target products of which are plastic correspond to the pre-determined printing license. Alternatively, the pre-determined printing license may correspond to a target print file whose class is a class of a target product, for example, corresponds to a target print file a class of a target product of which is safe product. The pre-determined printing license may also correspond to a target print file of another preset category. No limitation is set thereto herein.
The 3D printing design system receives the pre-determined printing license sent by the licensing center, and stores the pre-determined printing license.
Steps 402 to 405 are basically the same as steps 301 to 304, and details are not described herein again.
If in step 405, the 3D printing design system determines that the target print file meets the first safety criterion, step 409 is performed; or if the 3D printing design system determines that the target print file does not meet the first safety criterion, step 406 is performed.
If the 3D printing design system determines that the target print file does not meet the first safety criterion, the 3D printing design system determines whether a pre-determined printing license corresponding to the target print file is stored.
If the 3D printing design system determines that the pre-determined printing license corresponding to the target print file is stored, step 409 is performed.
If the 3D printing design system determines that the pre-determined printing license corresponding to the target print file is not stored, step 407 is performed.
If the 3D printing design system determines that the pre-determined printing license corresponding to the target print file is not stored, the 3D printing design system sends first license request information to the printing licensing center.
The printing licensing center is configured to determine whether the request information received by the printing licensing center meets a second safety criterion, and if yes, issue a printing license corresponding to the file, where the printing license indicates that a 3D printing system is allowed to perform printing according to the target print file.
The first license request information is used to request the printing licensing center for a printing license, where the first license request information may include the target print file, or the attribute of the target product, or the class of the target product, or may be other information, which is not limited herein.
After the 3D printing design system sends the first license request information to the printing licensing center, the printing licensing center determines whether the first license request information meets the second safety criterion, and sends a printing license according to a determining result. The 3D printing design system determines whether the first printing license sent by the licensing center is received.
If the 3D printing design system determines that the first printing license sent by the licensing center is received, it indicates that the printing licensing center determines that the first license request information meets the second safety criterion, and step 409 is performed.
If the 3D printing design system determines that the first printing license sent by the licensing center is not received, it indicates that the printing licensing center determines that the first license request information does not meet the second safety criterion, and step 410 is performed.
If the 3D printing design system determines that the target print file meets the first safety criterion, or determines that the pre-determined printing license corresponding to the target print file is stored, or determines that the first printing license sent by the licensing center is received, the 3D printing design system sends the target print file to a 3D printing system.
The executing, by the 3D printing design system, another operation if the 3D printing design system determines that the target print file does not meet the first safety criterion, and determines that the pre-determined printing license corresponding to the target print file is not stored, and the 3D printing design system determines that the first printing license sent by the licensing center is not received includes: skipping, by the 3D printing design system, the target print file to the 3D printing system, or processing, by the D printing design system, the target print file and then sending the target print file to the 3D printing system, or may be another operation, which is not limited in this embodiment.
Step 401 may also be performed after any one of steps 402 to 405, which is not limited in this embodiment as long as step 401 is performed before step 406.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between the 3D printing design system, the printing licensing center, and the 3D printing system.
In the embodiment shown in
In the embodiment shown in
Steps 501 to 505 are basically the same as steps 401 to 405, and details are not described herein again.
If in step 505, the 3D printing design system determines that the target print file meets the first safety criterion, step 509 is performed; or if the 3D printing design system determines that the target print file does not meet the first safety criterion, step 506 is performed.
If the 3D printing design system determines that the target print file does not meet the first safety criterion, the 3D printing design system determines whether a pre-determined printing license corresponding to the target print file is stored.
If the 3D printing design system determines that the pre-determined printing license corresponding to the target print file is stored, step 509 is performed.
If the 3D printing design system determines that the pre-determined printing license corresponding to the target print file is not stored, step 507 is performed.
Steps 507 and 508 are basically the same as steps 407 and 408, and details are not described herein again.
If the 3D printing design system determines that the first printing license sent by the licensing center is received, it indicates that the printing licensing center determines that the first license request information meets the second safety criterion, and step 509 is performed.
If the 3D printing design system determines that the first printing license sent by the licensing center is not received, it indicates that the printing licensing center determines that the first license request information does not meet the second safety criterion, and step 510 is performed.
Steps 509 and 510 are basically the same as steps 409 and 410, and details are not described herein again.
The 3D printing design system may acquire the correspondence between the product class and the first safety criterion, and determine, according to the correspondence, whether the target print file meets the first safety criterion. However, in actual application, the correspondence between the product class and the first safety criterion may change due to a reason such as a government policy or scientific and technological development. For example, according to an original correspondence between the product class and the first safety criterion, a particular type of knife meets the first safety criterion, but according to an updated correspondence between the product class and the first safety criterion, the type of knife does not meet the first safety criterion. If the correspondence between the product class and the first safety criterion changes, but the 3D printing design system does not update the correspondence, a result of determining by the 3D printing design system according to the correspondence that is not updated is not accurate. Therefore, the 3D printing design system needs to constantly update the correspondence between the product class and the first safety criterion.
In this embodiment, a latest correspondence between the product class and the first safety criterion is stored on a target server, and the 3D printing design system acquires a target server address from the printing licensing center, where the target server address is an address of the target server.
After acquiring the target server address from the printing licensing center, the 3D printing design system accesses the target server address, and downloads an update file from the target server, where the update file is used to update the correspondence between the product class and the first safety criterion.
After downloading the update file from the target server, the 3D printing design system updates the correspondence between the product class and the first safety criterion according to the update file.
Steps 511 to 513 may also be performed before any one of steps 501 to 510, which is not limited in this embodiment.
Steps 511 to 513 may also be performed once every a preset time length, which is not limited in this embodiment.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between the 3D printing design system, the printing licensing center, and the 3D printing system.
In this embodiment, a 3D printing design method is provided, where a 3D printing design system determines safety of a target print file according to a correspondence between a product class and a first safety criterion, and constantly updates the correspondence between the product class and the first safety criterion. According to this method, determining by the 3D printing design system and a printing licensing center on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens. In addition, the 3D printing design system constantly updates the correspondence between the product class and the first safety criterion, so that the correspondence, acquired by the 3D printing design system, between the product class and the first safety criterion has better real-time performance, and determining on safety of the target print file according to the correspondence between the product class and the first safety criterion is more accurate and credible.
For ease of understanding of the foregoing embodiment, a description is provided below using a specific application scenario of the foregoing embodiment as an example.
A 3D printing design system receives a pre-determined printing license from a licensing center, and stores the pre-determined printing license. Content of the pre-determined printing license is a gun whose purpose is police use meets the pre-determined printing license, but a gun whose purpose is military use does not meet the pre-determined printing license.
A user designs a print file of a small gun using the 3D printing design system. After determining that the design of the print file is completed, the 3D printing design system acquires an attribute of a target product of the print file, where the attribute includes a designed product is a gun, a gun caliber is 5.8 millimeters, and the gun is used for a military purpose. It can be learned from the attribute that the product designed in the print file is a gun, and because the gun is harmful, the 3D printing design system determines that a class of the target product of the print file is non-safe product, and determines that the print file does not meet a first safety criterion. Accordingly, the 3D printing design system determines whether a pre-determined printing license corresponding to the print file is stored. Because the pre-determined printing license stored in the 3D printing design system allows only the purpose of police use, and does not allow the purpose of military use, the 3D printing design system determines that the pre-determined printing license corresponding to the print file is not stored. Therefore, the 3D printing design system sends first license request information to the printing licensing center, where content of the first license request information is the attribute of the target product of the print file.
After safety determining, the printing licensing center considers that the small gun can be produced, and therefore, the printing licensing center sends a first printing license to the 3D printing design system. After receiving the first printing license, the 3D printing design system sends the print file of the small gun to a 3D printing system.
Every a preset time length, the 3D printing design system acquires a target server address from the licensing center, accesses the target server address, downloads an update file from a target server, and updates a correspondence between the product class and the first safety criterion according to the update file.
In the embodiments shown in
In an entire 3D printing process, a 3D printing design system is mainly responsible for designing a target print file, and an operation of printing the target print file is mainly completed by a 3D printing system. To print the target print file, the 3D printing system first needs to acquire the target print file.
The 3D printing system may acquire the target print file from the 3D printing design system, or may acquire the target print file from a printing licensing center, or may acquire the target print file by another means, which is not limited herein.
In the embodiments shown in
If the 3D printing system determines that the second printing license sent by the printing licensing center is received, it indicates that the printing licensing center determines that the first license request information meets the second safety criterion, that is, the target print file meets the second safety criterion, and therefore, the 3D printing system prints the target print file.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between the 3D printing design system, the printing licensing center, and the 3D printing system.
In this embodiment, a 3D printing method is provided, where a 3D printing system acquires a target print file, determines whether a second printing license sent by a printing licensing center is received, and if a determining result is yes, prints the target print file. In this embodiment, by determining whether the second printing license is received, determining by the 3D printing system on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens.

In the embodiment shown in
In an entire 3D printing process, a 3D printing design system is mainly responsible for designing a target print file, and an operation of printing the target print file is mainly completed by a 3D printing system. To print the target print file, the 3D printing system first needs to acquire the target print file.
The 3D printing system may acquire the target print file from the 3D printing design system, or may acquire the target print file from a printing licensing center, or may acquire the target print file by another means, which is not limited herein.
After determining the target print file, the 3D printing system determines whether the target print file meets the third safety criterion. There are many methods for the 3D printing system to determine whether the target print file meets the third safety criterion, which are described in detail in subsequent embodiments, and no limitation is set thereto in this embodiment.
If the 3D printing system determines that the target print file meets the third safety criterion, the 3D printing system prints the target print file. If the 3D printing system determines that the target print file does not meet the third safety criterion, the 3D printing design system may not print the target print file, or may process the target print file and then print the target print file, or another method may be used, which is specifically described in detail in subsequent embodiments, and no limitation is set thereto in this embodiment.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between the 3D printing design system, the printing licensing center, and the 3D printing system.
In this embodiment, after acquiring a target print file, a 3D printing and manufacturing system determines whether the target print file meets a third safety criterion, and if the target print file meets the third safety criterion, prints the target print file. In this embodiment, by determining by the 3D printing system whether the target print file meets the third safety criterion, determining by the 3D printing system on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens.

There are many criterions for acquiring, according to the attribute of the target product, the class of the target product corresponding to the target print file, including determining the class of the target product according to a category, in the attribute of the target product, of the raw material of the target product. For example, if the category of the raw material of the target product is iron, the class of the target product is metal product; or if the category of the raw material of the target product is polyethylene, the class of the target product is plastic product. Alternatively, the class of the target product is determined according to a purpose, in the attribute of the target product, of the target product, and if the purpose of the target product is walk replacement, the class of the target product is vehicle; or if the purpose of the target product is containing liquid, the class of the target product is container.

No limitation is set thereto herein.
The class of the target product may also simply include safe product and non-safe product. For example, if the 3D printing system learns from the attribute of the target product that the raw material of the target product includes a prohibited raw material, or a spatial shape of the target product is a shape of a prohibited article such as a weapon, or a manufacturing technological process of the target product relates to a technological process of a prohibited article, or the target product is used in a behavior activity that may harm life and property safety of citizens, the 3D printing system determines that the class of the target product is non-safe product. The 3D printing system may also determine, according to an attribute of the target product in another aspect, whether the class of the target product is non-safe product or safe product. No limitation is set thereto herein.
After acquiring the class of the target product corresponding to the target print file, the 3D printing system may further determine whether the target print file meets a third safety criterion. There is a correspondence between the product class and the third safety criterion. For example, a metal product corresponds to meeting the third safety criterion, and a plastic product corresponds to not meeting the third safety criterion.
There are many methods for acquiring the correspondence between the product class and the third safety criterion, where the correspondence may be manually set, or may be actively acquired by the 3D printing system from a server, or may be passively received by the 3D printing system from a server, or another manner may be used. No limitation is set thereto herein. The 3D printing system determines, according to the correspondence between the product class and the third safety criterion, whether the target print file corresponding to the class of the target product meets the third safety criterion.
Particularly, if in step 803, the product class includes only safe product and non-safe product, the determining, by the 3D printing system according to a correspondence between the product class and a third safety criterion, whether the target print file meets the third safety criterion includes: if the class of the target product is safe product, determining, by the 3D printing system, that the target print file meets the third safety criterion, or if the class of the target product is non-safe product, determining, by the 3D printing system, that the target print file does not meet the third safety criterion.

If the 3D printing system determines that the target print file meets the third safety criterion, or determines that the second printing license sent by the licensing center is received, the 3D printing system prints the target print file.
The executing, by the 3D printing system, another operation if the 3D printing system determines that the target print file does not meet the third safety criterion or the 3D printing system determines that the second printing license sent by the licensing center is not received includes: skipping, by the 3D printing system, the target print file to the 3D printing system, or processing, by the 3D printing and manufacturing system, the target print file and then sending the target print file to the 3D printing system, or may be another operation, which is not limited in this embodiment.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between a 3D printing design system, the printing licensing center, and the 3D printing system.
In this embodiment, how a 3D printing system specifically performs another operation when the 3D printing system determines that a target print file does not meet a third safety criterion is explained in detail. If the 3D printing system determines that the target print file does not meet the third safety criterion, the 3D printing system sends second license request information to a printing licensing center, and then determines whether a second printing license sent by the licensing center is received. If the 3D printing system determines that the second printing license sent by the licensing center is received, it indicates that the printing licensing center determines that the second license request information meets a second safety criterion, and the 3D printing system prints the target print file. According to this method provided in this embodiment, quadratic determining by the 3D printing system and the printing licensing center on safety of the target print file is implemented. Compared with separate safety determining by the 3D printing system or separate safety determining by the licensing center, the quadratic determining in this embodiment improves accuracy of determining on safety of the target print file in an entire 3D printing process, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens.
In the embodiment shown in
A licensing center needs to receive license requests sent by one or more 3D printing systems, and therefore the amount of data received by the licensing center is huge, and processing of relatively much data causes many problems such as low efficiency of the licensing center and excessively heavy load of a server. Therefore, the licensing center may send a pre-determined printing license to a 3D printing system, where the pre-determined printing license corresponds to a target print file of a preset category, and may specifically correspond to a target print file having an attribute of a target product. For example, if the pre-determined printing license corresponds to a target print file a category of a raw material of a target product of which is plastic, all target print files categories of raw materials of target products of which are plastic correspond to the pre-determined printing license. Alternatively, the pre-determined printing license may correspond to a target print file whose class is a class of a target product, for example, corresponds to a target print file a class of a target product of which is safe product. The pre-determined printing license may also correspond to a target print file of another preset category. No limitation is set thereto herein.
The 3D printing system receives the pre-determined printing license sent by the licensing center, and stores the pre-determined printing license.
Steps 1002 to 1005 are basically the same as steps 901 to 904, and details are not described herein again.
If in step 1005, the 3D printing system determines that the target print file meets the third safety criterion, step 1009 is performed.
If the 3D printing system determines that the target print file does not meet the third safety criterion, step 1006 is performed.
If the 3D printing system determines that the target print file does not meet the third safety criterion, the 3D printing system determines whether a pre-determined printing license corresponding to the target print file is stored.
If the 3D printing system determines that the pre-determined printing license corresponding to the target print file is stored, step 1009 is performed.
If the 3D printing system determines that the pre-determined printing license corresponding to the target print file is not stored, step 1007 is performed.
If the 3D printing system determines that the target print file does not meet the third safety criterion, the 3D printing system sends second license request information to the printing licensing center.
The printing licensing center is configured to determine whether the request information received by the printing licensing center meets a particular safety criterion, and if yes, issue a printing license corresponding to the file, where the printing license indicating that the 3D printing system is allowed to perform printing according to the target print file.
The second license request information is used to request the printing licensing center for a printing license, where the second license request information may include: the target print file, or the attribute of the target product, or the class of the target product, or may be other information, which is not limited herein.
After the 3D printing system sends the second license request information to the printing licensing center, the printing licensing center determines whether the second license request information meets a second safety criterion, and if yes, sends a second printing license to the 3D printing system. The 3D printing system determines whether the second printing license sent by the licensing center is received.
If the 3D printing system determines that the second printing license sent by the licensing center is received, it indicates that the printing licensing center determines that the second license request information meets the second safety criterion, and step 1009 is performed.
If the 3D printing system determines that the second printing license sent by the licensing center is not received, it indicates that the printing licensing center determines that the second license request information does not meet the second safety criterion, and step 1010 is performed.
If the 3D printing system determines that the target print file meets the third safety criterion, or determines that the pre-determined printing license corresponding to the target print file is stored, or determines that the second printing license sent by the licensing center is received, the 3D printing system prints the target print file.
The executing, by the 3D printing system, another operation if the 3D printing system determines that the target print file does not meet the third safety criterion, determines that the pre-determined printing license corresponding to the target print file is not stored, and determines that the second printing license sent by the licensing center is not received includes skipping, by the 3D printing design system, the target print file to the 3D printing system, or processing, by the D printing design system, the target print file and then sending the target print file to the 3D printing system, or may be another operation, which is not limited in this embodiment.
Step 1001 may also be performed after any one of steps 1002 to 1005, which is not limited in this embodiment as long as step 1001 is performed before step 1006.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between a 3D printing design system, the printing licensing center, and the 3D printing system.
In the embodiment shown in
In the embodiment shown in
Steps 1101 to 1105 are basically the same as steps 1001 to 1005, and details are not described herein again.
If in step 1105, the 3D printing system determines that the target print file meets the third safety criterion, step 1109 is performed.
If the 3D printing system determines that the target print file does not meet the third safety criterion, step 1106 is performed.
If the 3D printing system determines that the target print file does not meet the third safety criterion, the 3D printing system determines whether a pre-determined printing license corresponding to the target print file is stored.
If the 3D printing system determines that the pre-determined printing license corresponding to the target print file is stored, step 1109 is performed.
If the 3D printing system determines that the pre-determined printing license corresponding to the target print file is not stored, step 1107 is performed.
Steps 1107 and 1108 are basically the same as steps 1007 and 1008, and details are not described herein again.
If the 3D printing system determines that the second printing license sent by the licensing center is received, it indicates that the printing licensing center determines that the second license request information meets the second safety criterion, and step 1109 is performed.
If the 3D printing system determines that the second printing license sent by the licensing center is not received, it indicates that the printing licensing center determines that the second license request information does not meet a second safety criterion, and step 1110 is performed.
Steps 1109 and 1110 are basically the same as steps 1009 and 1010, and details are not described herein again.
The 3D printing system may acquire the correspondence between the product class and the third safety criterion, and determine, according to the correspondence, whether the target print file meets the third safety criterion. However, in actual application, the correspondence between the product class and the third safety criterion may change due to a reason such as a government policy or scientific and technological development. For example, according to an original correspondence between the product class and the third safety criterion, a particular type of knife meets the third safety criterion, but according to an updated correspondence between the product class and the third safety criterion, the type of knife meets the third safety criterion. If the correspondence between the product class and the third safety criterion changes, but the 3D printing system does not update the correspondence, a result of determining by the 3D printing system according to the correspondence that is not updated is not accurate. Therefore, the 3D printing system needs to constantly update the correspondence between the product class and the third safety criterion.
In this embodiment, a latest correspondence between the product class and the third safety criterion is stored on a target server, and the 3D printing system acquires a target server address from the printing licensing center, where the target server address is an address of the target server.
After acquiring the target server address from the printing licensing center, the 3D printing system accesses the target server address, and downloads an update file from the target server, where the update file is used to update the correspondence between the product class and the third safety criterion.
After downloading the update file from the target server, the 3D printing system updates the correspondence between the product class and the third safety criterion according to the update file.
Step 1101 may also be performed after any one of steps 1102 to 1105, which is not limited in this embodiment as long as step 1101 is performed before step 1106.
Steps 1111 to 1113 may also be performed before any one of steps 1101 to 1110, which is not limited in this embodiment.
Steps 1111 to 1113 may also be performed once every a preset time length, which is not limited in this embodiment.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between a 3D printing design system, the printing licensing center, and the 3D printing system.
In this embodiment, a 3D printing method is provided, where a 3D printing system determines safety of a target print file according to a correspondence between a product class and a third safety criterion, and constantly updates the correspondence between the product class and the third safety criterion. According to this method, quadratic determining by the 3D printing system and a printing licensing center on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens. In addition, the 3D printing system constantly updates the correspondence between the product class and the third safety criterion, so that the correspondence, acquired by the 3D printing system, between the product class and the third safety criterion has better real-time performance, and determining on safety of the target print file according to the correspondence between the product class and the third safety criterion is more accurate and credible.
For ease of understanding of the foregoing embodiment, a description is provided below using a specific application scenario of the foregoing embodiment as an example.
A 3D printing system receives a pre-determined printing license from a licensing center, and stores the pre-determined printing license. Content of the pre-determined printing license a gun whose purpose is police use meets the pre-determined printing license, but a gun whose purpose is military use does not meet the pre-determined printing license.
A user designs a print file of a small gun using a 3D printing design system. The 3D printing system acquires the print file from the 3D printing design system, and then acquires an attribute of a target product of the print file, where the attribute includes a designed product is a gun, a gun caliber is 5.8 millimeters, and the gun is used for a military purpose. It can be learned from the attribute that the product designed in the print file is a gun, and because the gun is harmful, the 3D printing system determines that a class of the target product of the print file is non-safe product, and determines that the print file does not meet a third safety criterion. Accordingly, the 3D printing system determines whether a pre-determined printing license corresponding to the print file is stored. Because the pre-determined printing license stored in the 3D printing system allows only the purpose of police use, and does not allow the purpose of military use, the 3D printing system determines that the pre-determined printing license corresponding to the print file is not stored. Therefore, the 3D printing system sends second license request information to the printing licensing center, where content of the second license request information is the attribute of the target product of the print file.
After safety determining, the printing licensing center considers that the small gun can be produced, and therefore, the printing licensing center sends a third printing license to the 3D printing design system. After receiving the third printing license, the 3D printing system prints the print file, where an obtained target product is a small gun.
Every a preset time length, the 3D printing system acquires a target server address from the licensing center, accesses the target server address, downloads an update file from a target server, and updates a correspondence between the product class and the third safety criterion according to the update file.
In the embodiments shown in
In the embodiment shown in any figure of
Therefore, in this embodiment, the printing licensing center receives the first license request information sent by the 3D printing design system.
After receiving the first license request information sent by the 3D printing design system, the printing licensing center determines whether the first license request information meets a second safety criterion.
If the printing licensing center determines that the first license request information meets the second safety criterion, the printing licensing center considers that the target print file designed by the 3D printing design system is relatively safe, and printing of the target print file can be authorized. Therefore, the printing licensing center sends a first printing license to the 3D printing design system. The first printing license is used to allow the 3D printing design system to send the target print file corresponding to the first license request information to a 3D printing system.
If the printing licensing center determines that the first license request information does not meet the second safety criterion, the printing licensing center may not send the first printing license to the 3D printing design system, or may perform another operation, which is not limited in this embodiment.
The printing licensing center may determine, according to the attribute of the target product corresponding to the first license request information, the class of the target product, or a safety level of the 3D printing design system that sends the first license request information, whether the first license request information meets the second safety criterion, or may determine, in another manner, whether the first license request information meets the second safety criterion, which is not limited in this embodiment. The safety level is used to indicate safety of the 3D printing design system. Request information sent by a 3D printing design system having a higher safety level is more easily considered by the printing licensing center as meeting the second safety criterion.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between the 3D printing design system and the printing licensing center.
In this embodiment, a 3D printing licensing method is provided, where regulation on a target product is implemented from the perspective of a printing licensing center. The printing licensing center receives first license request information sent by a 3D printing design system, determines whether the first license request information meets a second safety criterion, and if yes, sends a first printing license to the 3D printing design system. According to this method, determining by the printing licensing center on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens.
In the embodiment shown in
Step 1301 is basically the same as step 1201, and details are not described herein again.
After receiving the first license request information sent by the 3D printing design system, the printing licensing center acquires a license request class according to the first license request information. The license request class is used to indicate a classification of the license request information. There may be many license request information classification manners. For example, classification is performed according to a purpose, to obtain a class of commercial use, a class of civil use, or a class of military use; or classification is performed according to a raw material of a target product, to obtain a metal class or a non-metal class; or classification is performed in another manner. Particularly, the license request class may also be the same as or different from a class of the target product in classification, which is not limited herein.
One printing licensing center needs to process various license request information sent by one or more 3D printing design systems or 3D printing systems. The printing licensing center receives the license request information, and determines whether the request information meets a second safety criterion. However, a concept of the second safety criterion is very flexible. For example, for a particular class of target product that is less harmful, such as a regulated knife, the government allows a relatively small quantity of target products of the class to be circulated on the market, but does not allow a relatively large quantity of target products of the class to be circulated on the market. Therefore, after acquiring the license request class, the printing licensing center acquires a quantity of times of processing on license request information corresponding to the license request class.
There are many methods for the printing licensing center to acquire the quantity of times of processing on the license request information corresponding to the license request class, includes counting, by the printing licensing center, processed license request information of different classes; each time license request information is processed, add 1 to a count value of a license request class corresponding to the license request information, and storing a counting result in a memory; and when necessary, acquiring, from the memory, a quantity of times of processing on the license request information corresponding to the license request class. The printing licensing center may also acquire, using another method, the quantity of times of processing on the license request information corresponding to the license request class. No limitation is set in this embodiment.
To limit a particular class of target product circulated on the market to only a relatively small quantity, in this embodiment, a preset quantity of times is set in the printing licensing center. After acquiring the quantity of times of processing on the license request information corresponding to the license request class, the printing licensing center determines whether the acquired quantity of times reaches the preset quantity of times.
There are multiple classes of license request information processed by the printing licensing center, and correspondingly, the preset quantity of times is not necessarily constant. For license request information of a relatively dangerous class, such as license request information whose corresponding target product is a gun or ammunition, a preset quantity of times corresponding to the license request information needs to be relatively small; for license request information of a relatively safe class, such as license request information corresponding to an article of daily use, a preset quantity of times corresponding to the license request information needs to be relatively large. Specifically, it may be implemented as follows: all classes of license request information correspond to a same preset quantity of times, or a plurality of classes of license request information corresponds to a same preset quantity of times, or all classes of license request information each correspond to different preset quantities of times. A relationship between different classes of license request information and a preset quantity of times may also be implemented in another form, and details are not described herein.
If the printing licensing center determines that the quantity of times of processing on the license request information corresponding to the license request class reaches the preset quantity of times, step 1305 is performed.
If the printing licensing center determines that the quantity of times of processing on the license request information corresponding to the license request class does not reach the preset quantity of times, step 1306 is performed.
If the printing licensing center determines that the quantity of times of processing on the license request information corresponding to the license request class reaches the preset quantity of times, it indicates that the printing licensing center has issued a relatively large quantity of licenses and authorizations for license requests of the class. To prevent more target products corresponding to the license request class from being produced, the printing licensing center does not send a first printing license to the 3D printing design system.
If the printing licensing center determines that the quantity of times of processing on the license request information corresponding to the license request class does not reach the preset quantity of times, the printing licensing center determines whether the first license request information meets a second safety criterion.
If the printing licensing center determines that the first license request information meets the second safety criterion, step 1307 is performed.
If the printing licensing center determines that the first license request information does not meet the second safety criterion, step 1308 is performed.
If the printing licensing center determines that the first license request information meets the second safety criterion, the printing licensing center considers that the target print file designed by the 3D printing design system is relatively safe, and printing of the target print file can be authorized. Therefore, the printing licensing center sends a first printing license to the 3D printing design system. The first printing license is used to allow the 3D printing design system to send the target print file corresponding to the first license request information to a 3D printing system.
The executing, by the printing licensing center, another operation if the printing licensing center determines that the first license request information does not meet the second safety criterion includes skipping, by the printing licensing center, sending the first printing license to the 3D printing design system, or may be another operation, which is not limited in this embodiment.
To prevent information such as the target print file, the license request information, or the printing license from being tampered and impact on determining on safety of the target print file, asymmetric cryptography may be performed for data transmission between the 3D printing design system, the printing licensing center, and the 3D printing system.
The printing licensing center may determine, according to an attribute of the target product corresponding to the first license request information, the class of the target product, or a safety level of the 3D printing design system that sends the first license request information, whether the first license request information meets the second safety criterion, or may determine, in another manner, whether the first license request information meets the second safety criterion, which is not limited in this embodiment. The safety level is used to indicate safety of the 3D printing design system. Request information sent by a 3D printing design system having a higher safety level is more easily considered by the printing licensing center as meeting the second safety criterion.
In this embodiment, a 3D printing licensing method is provided, where regulation on a target product is implemented from the perspective of a printing licensing center. The printing licensing center receives first license request information sent by a 3D printing design system, determines whether the first license request information meets a second safety criterion, and if yes, sends a first printing license to the 3D printing design system. According to this method, determining by the printing licensing center on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens. In addition, the printing licensing center determines whether a quantity of times of processing on license request information corresponding to a license request class reaches a preset quantity of times, and if yes, skips sending a first printing license to the 3D printing design system, so that the printing licensing center licenses and authorizes only license request information within the preset quantity of times, which implements control of a production quantity of the target product, and further enhances regulation on safety of the print file.
For ease of understanding of the foregoing embodiment, a description is provided below using a specific application scenario of the foregoing embodiment as an example.
A printing licensing center receives first license request information sent by a 3D printing design system, where the first license request information is an attribute of a target product of a print file, where the target product of the print file is a small gun, and the target attribute includes a target product is a gun, a gun caliber is 5.8 millimeters, and the gun is used for a military purpose.
After receiving the first license request information, the printing licensing center acquires a license request class according to the first license request information, and obtains that the license request class is a gun class. The printing licensing center has processed license request information of the gun class 345 times in total, which does not reach a preset quantity of times 500 times, and accordingly, the printing licensing center determines whether the first license request information meets a second safety criterion. A determining criterion of the printing licensing center is if the gun caliber included in the first license request information is less than 6 millimeters, it is considered that the first license request information meets the second safety criterion. Therefore, the printing licensing center considers that the first license request information meets the second safety criterion, and the print file can be printed. Accordingly, the printing licensing center sends a first printing license to the 3D printing design system.

In the foregoing embodiments, multiple 3D printing design methods, 3D printing methods, and 3D printing licensing methods are given. In the following embodiments, apparatuses configured to implement the foregoing methods are described in detail, and for content that is not described in detail herein, reference may be made to descriptions in the foregoing methods.
Referring to
In this embodiment, after the file determining module 1601 determines a target print file, the first safety determining module 1602 determines whether the target print file meets a first safety criterion, and if the target print file meets the first safety criterion, the file sending module 1603 sends the target print file to a 3D printing apparatus, so that the 3D printing apparatus performs printing according to the target print file. By determining whether the target print file meets the first safety criterion, determining by the 3D printing design apparatus on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens.
In the embodiment shown in
In this embodiment, the first safety determining module is detailed based on the embodiment shown in
In the embodiment shown in
In this embodiment, how another operation is specifically performed when the 3D printing design apparatus determines that a target print file does not meet a first safety criterion is explained in detail. If the first safety determining module 1802 determines that the target print file does not meet the first safety criterion, the first request sending module 1803 sends first license request information to a 3D printing licensing apparatus, and the first license determining module 1804 determines whether a first printing license sent by the 3D printing licensing apparatus is received.

In the embodiment shown in
In this embodiment, a 3D printing design apparatus is provided, where the first safety determining module 2003 determines safety of a target print file according to a correspondence between a product class and a first safety criterion, and the first criterion update module 2010 constantly updates the correspondence between the product class and the first safety criterion. According to this method, determining by the 3D printing design apparatus and a 3D printing licensing apparatus on safety of the target print file is implemented, which further implements regulation on a target product, resolves a problem of difficulty to regulate production of a high-danger article, and ensures social stability and personal safety of citizens. In addition, the first criterion update module 2010 constantly updates the correspondence between the product class and the first safety criterion, so that the correspondence, used by the first safety determining module 2003, between the product class and the first safety criterion has better real-time performance, and determining on safety of the target print file according to the correspondence between the product class and the first safety criterion is more accurate and credible.
For ease of understanding of the foregoing embodiment, a description is provided below using a specific application scenario of the foregoing embodiment as an example.
The first preset storage module 2001 receives a pre-determined printing license from a 3D printing licensing apparatus, and stores the pre-determined printing license. Content of the pre-determined printing license is a gun whose purpose is police use meets the pre-determined printing license, but a gun whose purpose is military use does not meet the pre-determined printing license.
A user designs a print file of a small gun using the 3D printing design apparatus. After the file determining module 2002 determines that the design of the print file is completed, the first attribute acquiring unit 20031 acquires an attribute of a target product of the print file, where the attribute includes a designed product is a gun, a gun caliber is 5.8 millimeters, and the gun is used for a military purpose. It can be learned from the attribute that the product designed in the print file is a gun, and because the gun is harmful, the first class acquiring unit 20032 determines that a class of the target product of the print file is non-safe product, and the first safety determining unit 20033 determines that the print file does not meet a first safety criterion. Accordingly, the first preset determining module 2004 determines whether a pre-determined printing license corresponding to the print file is stored. Because the pre-determined printing license stored in the first preset storage module 2001 allows only the purpose of police use, and does not allow the purpose of military use, the first safety determining unit 20033 determines that the pre-determined printing license corresponding to the print file is not stored. Therefore, the first request sending module 2005 sends first license request information to the 3D printing licensing apparatus, where content of the first license request information is the attribute of the target product of the print file.
After safety determining, the 3D printing licensing apparatus considers that the small gun can be produced, and therefore, the 3D printing licensing apparatus sends a first printing license to the 3D printing design apparatus. After the first license determining module 2006 receives the first printing license, the file sending module 2007 sends the print file of the small gun to a 3D printing apparatus.
Every a preset time length, the first address acquiring module 2008 acquires a target server address from the 3D printing licensing apparatus, and the first address access module 2009 accesses the target server address, and downloads an update file from a target server. The first criterion update module 2010 updates a correspondence between the product class and the first safety criterion according to the update file.
