The present invention relates to a three-dimensional shaped object, a method of three-dimensionalizing a planar image, a method of manufacturing a three-dimensional plate, and a method of manufacturing a female mold.
A three-dimensional signboard is a signboard three-dimensionally representing a product or a mascot character of a company. As a known general method for manufacturing the three-dimensional signboard or other three-dimensional shaped objects, the following method of obtaining a three-dimensional shaped object is known. For example, clay or the like is used to create an original mold, and casting of plaster or the like is performed to create a female mold. Then, a resin is injected into the female mold. After the resin is cured, the resin is demolded so that a main body of the three-dimensional shaped object is shaped. Then, the surface of the main body is polished and applied with paint, and the paint is dried. However, this method requires high material cost in the painting step, and also requires a long work time because time for drying and curing the material is long. Accordingly, there is a problem in that the price of the three-dimensional shaped object is inevitably increased. Further, specialized knowledge and sophisticated technology are required in the painting step, and hence there is a problem in that a difference is caused in the quality of the finished three-dimensional shaped object depending on a worker.
As another method, the following method of obtaining a three-dimensional shaped object is known (see, for example, Patent Literature 1). Styrofoam or the like is cut so that the main body of the three-dimensional shaped object is shaped, and the surface of the main body is subjected to coating by applying rigid urethane or the like. After that, the surface of the main body is applied with paint. This method also requires specialized knowledge and sophisticated technology in the painting step, and a difference is caused in the quality of the finished three-dimensional shaped object depending on the worker. Moreover, there is a problem in that the method requires high material cost and long work time.

The present invention relates to a technology of manufacturing, from a planar image representing a form of an object to be shaped, a model (three-dimensional shaped object or three-dimensional plate) similar to the actual object. Examples of the planar image may include a photograph, a painting, a sketch, and an engineering drawing. However, the planar image is not limited thereto as long as the planar image is a two-dimensional representation of the form of the object to be shaped, and various images can be used. Examples of the usage application of the three-dimensional shaped object to be manufactured may include a three-dimensional signboard, a decorative article, and a food model, but the usage application is not limited thereto. Further, examples of the object to be shaped may include artificial objects such as a product and a mascot character, natural objects such as a mountain and a tree, an animal, and food (cooking). However, the object to be shaped is not limited thereto, and may be, for example, letters or symbols.
As illustrated in
In the shaping step S1, in order to three-dimensionally represent the planar image of the form of the object to be shaped, first, there is performed work (sectionalizing step S10) of sectionalizing the object to be shaped into a plurality of regions in the planar image. Specifically, the planar image is first divided into a part of the object to be shaped to be three-dimensionally represented and a part of a background not to be three-dimensionally represented. Next, for the part of the object to be shaped, a contour of each region forming the object to be shaped is extracted. Then, as illustrated in
In this embodiment, description is given of an example in which the main body is shaped by carving a core material having a thickness. Accordingly, in the shaping step S1, next, as illustrated in
In the line
As the core material 5, for example, foam of a synthetic resin such as polystyrene, polypropylene, polyethylene, polyurethane, polyethylene terephthalate, polycarbonate, or the like may be used. When the core material 5 is made of a foamed resin, the weight of the final-form three-dimensional shaped object can be reduced. The material for the core material 5 is riot limited to a foamed resin. For example, wood, synthetic wood such as a wood fiber board (for example, an MDF), or the like may be used, and any material which can be carved or cut may be used. A length L, a width W, and a thickness T of the core material 5 are not particularly limited, and can have various values and are set as appropriate depending on a length, a width, and a maximum thickness (height protruding out from the plane, which is added when a two-dimensional plane is converted into a three-dimensional object) of a final-form three-dimensional shaped object 100 (illustrated in
In the shaping step S1, next, there is performed work (processing step S12) of processing each of the plurality of parts 60A to 60N cut out from the core material 5 so that each part is formed into a predetermined shape in accordance with a corresponding region of the object 1 to be shaped. Specifically, for each of the regions 10A to 30N of the object 1 to be shaped in the planar image, it is inferred what shape or dimension each region takes in the final-form three-dimensional shaped object, and as illustrated in
In the processing step S12, the following work is also performed. Inferring the final-form three-dimensional shaped object, for example, chamfering is performed by rounding off the corners of the respective parts 60A to 60N forming the main body 6, or the surface shape is modified by, for example, shaving and smoothing the surfaces of the respective parts 60A to 60N or forming irregularities thereon. Thus, the appearance of the main body 6 is adjusted so as to come close to the final-form three-dimensional shaped object.
In the coating step S2 after the shaping step S1, although not shown, there is performed work of applying a base material to the surface of the main body 6 so as to protect the surface. With the coating of the base material, a property (for example, strength, durability, or the like) of the surface of the main body 6 can be enhanced, and further the surface of the main body 6 can be smoothened. Further, an adhesive property of a wrapping sticker 8 with respect to the surface of the main body 6 can be enhanced. Examples of the base material may include a water-based urethane resin paint, an epoxy resin paint, and an acrylic resin paint, but the base material is not particularly limited as long as the base material can be used for surface treatment of the main body 6. In this embodiment, the surface of each of the parts 60A to 60N forming the main body 6 is individually coated with the base material.
In the digitizing step S3 after the coating step S2, in order to create wrapping stickers 8A to 8N to be affixed to the surface of the main body 6, which are to be described later, there is performed work of digitizing the planar image so as to create image data of the object to be shaped. In the digitizing step S3, first, there is performed work (data collecting step S30) of importing the planar image as image data. Examples of a method of importing the planar image may include scanning the planar image and picking up an image by a camera, but the method is not particularly limited thereto. The imported image data is stored in a computer having various arithmetic functions. The computer includes, as a hardware configuration, although not shown, a CPU, a memory, an auxiliary storage device (HDD), and the like. The CPU executes various types of arithmetic processing by reading out various programs stored in the HDD to the memory so as to execute the programs. As the computer, for example, a desktop computer, a mobile computer such as a PDA, a multi-function mobile phone (smartphone), or the like may be used. The image data of the planar image can be made clear or modified through use of publicly-known various data correction methods.
In the digitizing step S3, next, there is performed work (data creating step S31) of creating image data for each region of the object 1 to be shaped based on the imported image data. Specifically, as illustrated in
In the data creating step S31, in this embodiment, the image data pieces 7A to 7N corresponding to the respective regions 10A to 10N of the object 1 to be shaped are formed by extending actual image data pieces 70A to 70N cut out from the imported image data along the contours of the regions of the object 1 to be shaped. Specifically, the image data pieces 7A to 7N include the actual image data pieces 70A to 70N, and additional image data pieces 71A to 71N added to at least parts around the actual image data pieces 70A to 70N. The actual image data pieces 70A to 70N match or substantially match the sizes of the upper surfaces among the surfaces of the respective parts 60A to 60N forming the main body 6. Meanwhile, the parts 60A to 60N forming the main body 6 have, in addition to the upper surfaces, side surfaces by the amount of the thickness because the planar image is three-dimensionalised, and it is difficult to cover the side surfaces of the respective parts 60A to 60N only by the actual image data pieces 70A to 70N. Accordingly, in this embodiment, in order to cover not only the upper surfaces but also the side surfaces of the respective parts 60A to 60N, in consideration of the thickness of each of the parts 60A to 60N, the additional image data pieces 71A to 71N created based on the actual image data pieces 70A to 70N are added around the actual image data pieces 70A to 70N for the respective parts. In this manner, the image data pieces 7A to 7N can also cover the side surfaces of the respective parts 60A to 60N for which the image data runs short when a planar image is three-dimensionalized.
As a method of extending the actual image data pieces 70A to 70N to form the image data pieces 7A to 7N, other than the above-mentioned addition of the additional image data pieces 71A and 71N to the actual image data pieces 70A to 70N, the actual image data pieces 70A to 70N may be expanded or parts thereof may be stretched.
In the sticker creating step S4 after the digitizing step S3, there is performed work of creating, through use of the image data pieces 7A to 7N of the respective regions 10A to 10N of the object 1 to be shaped in the planar image, which are created in the digitizing step S3, a plurality of wrapping stickers 8A to 8N (illustrated in
In the affixing step S5 after the sticker creating step S4, there is performed work of affixing the wrapping stickers 8A to 8N to the surface of the main body 6. Specifically, in this embodiment, as illustrated in
The core material 5 (illustrated in
The method of three-dimensionalizing a planar image according to this embodiment further includes, as illustrated in
First, in the thinning step S60, there is performed work of processing the core material 5 so that the thickness T (illustrated in
In the coating step S61 after the thinning step S60, although not shown, there is performed work of applying a base material to the surface of the core material 5 so as to protect the surface of the core material 5. With the coating of the base material, a property (for example, strength, durability, or the like) of the surface of the core material 5 can be enhanced, and further the surface of the core material 5 can be smoothened. Further, an adhesive property of a wrapping sticker 9 with respect to the surface of the core material 5 can be enhanced. As the base material, for example, the same material as that used in the surface treatment of the main body 6 may be used.
In the background adding step S62 after the coating step S61, there is performed work of providing the surface of the core material 5 with a background. For example, the surface of the core material 5 can be provided with the background as follows. Similarly to the main body 6, from image data created by importing a planar image, image data (background image data) for a part of the background of the planar image is created, and then the wrapping sticker 9 having this background image data printed thereon is created. Then, the wrapping sticker 9 is affixed to the surface of the core material 5. A method of providing the surface of the core material 5 with the background is not particularly limited. For example, a picture may be drawn on the surface of the core material 5 through use of pencils, paints, markers, or the like.
In the integrating step S7 after the background adding step S62, there is performed work of combining and integrating the plurality of parts 60A to 60N obtained after the affixing step S5 with the core material 5 obtained after the background creating step S6. The plurality of parts 60A to 60N are bonded to each other with an adhesive or the like 30 that the main body 6 is assembled, and the main body 6 is bonded to the core material 5 with an adhesive or the like. In this manner, as illustrated in
According to this embodiment described above, through use of a photograph or other planar images, for example, a product or a mascot character of a company can be three-dimensionalized at high accuracy and reality. Accordingly, an orderer of the three-dimensional shaped object 100, for example, a three-dimensional signboard can easily order the three-dimensional shaped object 100, and can grasp in advance the rough finished look of the finished three-dimensional shaped object.
Further, according to this embodiment, the material of the three-dimensional shaped object 100 to be manufactured is mainly the core material 5 made of a foamed resin, and hence the three-dimensional shaped object 100 has a small weight. Thus, the orderer can easily transport or install the three-dimensional shaped object 100, and less labor or cost is required for those kinds of work.
Further, according to this embodiment, the wrapping sticker 3 having printed thereon the image data derived from the planar image (for example, the photograph) of the form of the object 1 to be shaped is used to apply a decoration to the surface of the main body 6, and hence a painting step which has been required in the related-art method is not required. Thus, the material cost for manufacturing the three-dimensional shaped object 100 is reduced, and no time for curing or drying the material is required. In addition, when the three-dimensional shaped object 100 is manufactured, situations which require specialized knowledge or sophisticated technology are reduced. Thus, a worker for manufacturing the three-dimensional shaped object 100 can manufacture the three-dimensional shaped object 100 easily and with a short work time. As a result, the price of the three-dimensional shaped object 100 can be decreased, and there is no great difference in quality of the finished three-dimensional shaped object depending on the worker.
Further, according to this embodiment, the main body 6 to be formed into a three-dimensional shape is shaped by carving the core material 5, and hence work which has hitherto been generally performed so as to shape the main body is not required. In the work which has hitherto been generally performed, for example, clay or the like is used to create an original mold, and casting of plaster or the like is performed to create a female mold. Then, a main agent, for example, an FRP is injected into the female mold. After the main agent is cured, the main agent is demolded so that the main body of the three-dimensional shaped object is shaped. Thus, the worker for manufacturing the three-dimensional shaped object 100 can manufacture the three-dimensional shaped object 100 more easily and with a shorter work time.
When the method of three-dimensionalizing a planar image according to this embodiment and the related-art three-dimensional shaping method are compared with each other, it is understood that, in this embodiment, first, the time required for shaping the main body into a three-dimensional shape can be greatly reduced. Further, no rigid urethane is sprayed, and hence expensive equipment for spraying the rigid urethane is not required. Further, it is understood that, in this embodiment, the surface of the main body is not applied with paint, and hence the time required for applying the paint and the time for drying and curing the material can be greatly reduced.
As described above, according to this embodiment, the “high price” and the “requirement of highly specialized knowledge and technology,” which have been problems in the related-art three-dimensional shaping method, can be solved, and anyone can manufacture the three-dimensional shaped object easily and at lost cost without causing a great difference in quality.
Moreover, according to this embodiment, in the three-dimensional shaped object 100 to be manufactured, the main body 6 is divided into the plurality of parts 60A to 60N, and the plurality of parts 60A to 60N are each processed so as to be formed into a predetermined shape in accordance with a corresponding region of the object 1 to be shaped. After that, the plurality of parts 60A to 60N are re-combined with each other so that the main body 6 is formed into a three-dimensional shape. Thus, the main body 6 can be shaped into a three-dimensional shape more easily, and hence the three-dimensional shaped object 100 can be manufactured with a shorter work time.
In addition, the object 1 to be shaped greatly changes in shape at boundaries between the regions 10A to 10N. However, when the main body 6 of the three-dimensional shaped object 100 is formed of the plurality of parts 60A to 60N, in the three-dimensional shaped object 100, this change in shape can be represented sharp. Thus, the three-dimensional, shaped object 100 can be manufactured with a higher reproducibility, and a realistic well-finished object can be obtained.
Moreover, according to this embodiment, the three-dimensional shaped object 100 to be manufactured is covered with the wrapping stickers 8A to 8N not only on the upper surfaces but also on the side surfaces of the respective parts 60A to 60N forming the main body 6. Accordingly, the aesthetic appearance of the three-dimensional shaped object 100 can be enhanced. In addition, the wrapping stickers 8A to 8N affixed to the surfaces of the respective parts 60A to 60N are partially sandwiched between corresponding parts 60A to 60N and other parts 60A to 60N adjacent thereto, and hence the wrapping stickers 8A to 8N are prevented from rolling up and peeling off from the parts 60A to 60N. Thus, the aesthetic appearance of the three-dimensional shaped object 100 can be prevented from being degraded.
Moreover, according to this embodiment, the three-dimensional shaped object 100 to be manufactured is formed so that the main body 6 being a three-dimensional object protrudes out from a plate material (in this embodiment, the core material 5) being a two-dimensional plane provided with a background. Thus, with the combination of the three-dimensional object and the plane, the main body 6 being the three-dimensional object is emphasized, and the main body 6 being the three-dimensional object can look more realistic.
Moreover, according to this embodiment, when the main body 6 obtained before the wrapping sticker 8 is affixed thereto is used as an original mold, a female mold can easily be manufactured.
A method of manufacturing the female mold specifically includes, as illustrated in
Further, a plastic plate having affixed, on its surface, one wrapping sticker 8 having printed thereon the entire image data of the object 1 to be shaped, or a plastic plate having directly printed, on its surface, the entire image data of the object 1 to be shaped is arranged on the main body 6, and the plastic plate is heat-pressed through use of the main body 6 as a mold while vacuuming is performed between the plastic plate and the main body 6. After that, the plastic plate is demolded and finished. In this manner, an internally-illuminated three-dimensional plate having affixed, on its surface, the wrapping sticker 8 having printed thereon the image data of the object 1 to be shaped or an internally-illuminated three-dimensional plate having printed thereon the image data of the object 1 to be shaped can easily be manufactured. A plurality of those three-dimensional plates may be stacked and integrated with each other, or a plurality of those three-dimensional plates may be arranged side by side in a circumferential direction and integrated with each other so that, as an object to be shaped illustrated in
A method of manufacturing the three-dimensional plate specifically includes, as illustrated in
Further, the three-dimensional plate 14 can also be manufactured by the following method. The method specifically includes, as illustrated in
In the above, the embodiment of the present invention has been described, but the present invention is not limited to the above-mentioned embodiment, and various changes are possible within the range not departing from the object of the present invention.
For example, in the above-mentioned embodiment, each of the wrapping stickers 8A to 8N is not always required to cover the entire side surface of the corresponding one of the parts 60A to 60N, and is only required to cover a region viewable from the outside in the side surface of the corresponding one of the parts 60A to 60N.
Further, in the above-mentioned embodiment, the plurality of wrapping stickers 8A to 8N having printed thereon the image data pieces of the respective regions of the object 1 to be shaped are individually affixed to the surfaces of corresponding parts among the plurality of parts 60A to 60N of the main body 6, and then the plurality of parts 60A to 60N are bonded to each other so that the main body 6 is formed. However, the present invention is not limited thereto. As shown in Modification Example 1 of
Further, in the above-mentioned embodiment, the main body 6 is divided into the plurality of parts 60A to 60N, but, for example, when the object 1 to be shaped has a shape with less irregularities, as shown in Modification Examples 3 and 4 of
Further, in the above-mentioned embodiment, the main body 6 being the three-dimensional object is integrated with the core material 5 being the two-dimensional plane, but the two-dimensional plane to be integrated with the main body 6 is not always required to be the core material 5 from which the main body 6 (plurality of parts 60A to 60N) is cut out, and other plate materials may be used. In this embodiment, in the background creating step S6, the background is provided around a region in which the main body 6 is to be positioned in the surface of the plate material, and in the integrating step S7, the main body 6 obtained after the affixing step S5 is mounted on the surface of the plate material obtained after the background creating step S6 so that the main body 6 is positioned in the region, to thereby integrate the main body 6 with the plate material.
Further, in the above-mentioned embodiment, the main body 6 being the three-dimensional object is integrated with the core material 5 being the two-dimensional plane, but the main body 6 is not always required to be integrated with a two-dimensional plane. For example, as shown in Modification Examples 5 to 7 of
As another example, although not shown, a main body may be shaped by three-dimensionalizing the object to be shaped over the entire circumference of 360° based on the plurality of planar images relating to the form of the object to be shaped. After that, the surface of the main body may be coated with the base material, and further one wrapping sticker having printed thereon the entire image data of the object to be shaped may be affixed to the surface of the main body, or the plurality of wrapping stickers having printed thereon the image data pieces of the respective regions of the object to be shaped may be individually affixed to the surfaces of the corresponding regions of the main body. Thus, the three-dimensional shaped object 100 obtained by three-dimensionalizing the object to be shaped over the entire circumference of 360°0 may be manufactured. When the plurality of wrapping stickers are affixed, the plurality of wrapping stickers may overlap each other at edge parts, or may be pushed in at boundaries between adjacent regions of the main body.
Further, in the above-mentioned embodiment, when the three-dimensional shaped object 100 or the three-dimensional plate 14 is manufactured, the main body 6 is shaped by carving the core material 5 made of, for example, foam of a synthetic resin, but the three-dimensional shaping method for the main body 6 is not limited thereto. For example, the main body 6 may be made of clay, and the clay may be, for example, manually molded or molding may be performed by applying the clay to the inner surface of the mold so that the main body 6 is shaped. As another example, the main body 6 may be made of a plastic or a fiber reinforced plastic such as an FRP, and the molding may be performed by pouring a resin into the mold or applying or blowing the resin to the inner surface of the mold so that the main body 6 is shaped. As another example, the main body 6 may be shaped through use of an additive manufacturing method using a 3D printer or the like or other three-dimensional shaping methods.
Also in this embodiment, the main body 6 may be divided into the plurality of parts 60A to 60N, and the plurality of parts 60A to 60N may be each processed so as to be formed into a predetermined shape. Thus, the plurality of parts 60A to 60N may be combined with each other so that the main body 6 is shaped.
Specifically, in the shaping step, the object to be shaped is sectionalized into ad plurality of regions in the planar image, and the main body 6 is divided into a plurality of parts so as to correspond to the plurality of regions of the object to be shaped. The plurality of parts are each processed so as to be formed into a predetermined shape in accordance with a corresponding region of the object to be shaped. Thus, the plurality of parts are combined with each other so that the main body is shaped. Further, regarding the wrapping sticker, similarly to the above-mentioned embodiment, in the digitizing step, the image data is created for each region of the object to be shaped, and in the sticker creating step, a plurality of wrapping stickers having printed thereon the image data pieces of the respective regions of the object to be shaped are created. Then, in the affixing step, the corresponding wrapping sticker among the plurality of wrapping stickers is affixed to the surface of each of the plurality of parts. In this manner, even without shaping the main body through carving of the core material, the three-dimensional shaped object can be manufactured.
Further, similarly to Modification Example 2 of
Further, similarly to Modification Example 3 of
Also in those embodiments, the main body being the three-dimensional object may be integrated with a plate material being a two-dimensional plane. Specifically, in the background creating step, the background is provided around a region in which the main body is to be positioned in the surface of the plate material, and in the integrating step, the main body obtained after the affixing step is mounted on the surface of the plate material obtained after the background creating step so that the main body is positioned in the region, to thereby integrate the main body with the plate material.
Further, in the above-mentioned embodiment, regarding the object to be shaped, a main body three-dimensionally representing the object to be shaped by 180 degrees is shaped based on one planar image, but in the shaping step, a plurality of planar images showing the form of the object to be shaped from different angles may be used so that a train body three-dimensionally representing the object to be shaped by 360 degrees is shaped based on the plurality of planar images. In this case, in the digitizing step and the sticker creating step, a plurality of image data pieces of the object to be shaped are created based on the plurality of planar images, and a plurality of wrapping stickers having printed thereon the respective image data pieces are created. Then, in the affixing step, the plurality of wrapping stickers are individually affixed to the surfaces of the corresponding regions of the main body. Thus, the three-dimensional shaped object is manufactured. The plurality of wrapping stickers may overlap each other at edge parts, or may be pushed in at boundaries between adjacent regions of the main body.
