20180173202
The present disclosure relates to a three-dimensional shape information generating system, a three-dimensional shape forming apparatus, a three-dimensional shape information generating method, and a program.
In recent years, a 3D printing (three-dimensional modeling) technology capable of forming an arbitrary three-dimensional object has been rapidly developed. Such a 3D printing technology makes it possible to easily form a modeled object having a three-dimensional shape input by a user and can therefore be widely used to, for example, manufacture a design of a product or component for trial and create a model for presentation.
Further, there is studied forming a larger-scale structure by using the above-mentioned 3D printing technology. For example, forming a residence in which a person can live by using the 3D printing technology is studied in Non-Patent Literature 1 cited below.
However, in the above-mentioned Non-Patent Literature 1, only an artificial object such as a residence is studied as a three-dimensional-shaped object formed by using the 3D printing technology, and a structure including a natural object such as plants has not been studied. This is because plants need moisture and nourishment to grow and a growth environment is variously restricted, and therefore it is difficult to form a three-dimensional-shaped object that satisfies a growth environment of plants by using the 3D printing technology studied in the above-mentioned Non-Patent Literature 1 or the like.
Therefore, there has been required a technology of forming a three-dimensional-shaped object that satisfies a growth environment of plants, can be used to cultivate plants, and has an arbitrary outer shape.
In view of this, the present disclosure proposes a three-dimensional shape information generating system, a three-dimensional shape forming apparatus, a three-dimensional shape information generating method, and a program, each of which is new, is improved, and is capable of forming a three-dimensional-shaped object that has an arbitrary outer shape and is used to cultivate plants.

In addition, according to the present disclosure, there is provided a three-dimensional shape forming apparatus including: an outer shape information acquiring unit configured to acquire outer shape information indicating an outer shape of a three-dimensional-shaped object used to cultivate a plant; a shape information generating unit configured to generate, on the basis of the outer shape information, shape information indicating a shape of the three-dimensional-shaped object in which at least a part of a region has a three-dimensional mesh-like structure; and a three-dimensional shape forming unit configured to form the three-dimensional-shaped object on the basis of the shape information.
In addition, according to the present disclosure, there is provided a three-dimensional shape information generating method including: generating, by using a circuit, on the basis of outer shape information indicating an outer shape of a three-dimensional-shaped object used to cultivate a plant, shape information indicating a shape of the three-dimensional-shaped object in which at least a part of a region has a three-dimensional mesh-like structure; and outputting the shape information to cause a three-dimensional shape forming unit to form the three-dimensional-shaped object.
In addition, according to the present disclosure, there is provided a program for causing a computer to function as a shape information generating unit configured to generate, on the basis of outer shape information indicating an outer shape of a three-dimensional-shaped object used to cultivate a plant, shape information indicating a shape of the three-dimensional-shaped object in which at least a part of a region has a three-dimensional mesh-like structure.
According to the present disclosure, it is possible to form a three-dimensional-shaped object that has an outer shape indicated by acquired outer shape information and in which at least a part of a region has a three-dimensional mesh-like structure suitable to cultivate plants.
As described above, according to the present disclosure, it is possible to form a three-dimensional-shaped object that has an arbitrary outer shape and is used to cultivate plants.
Note that the effects described above are not necessarily limitative. With or in the place of the above effects, there may be achieved any one of the effects described in this specification or other effects that may be grasped from this specification.
Hereinafter, (a) preferred embodiment(s) of the present disclosure will be described in detail with reference to the appended drawings. In this specification and the appended drawings, structural elements that have substantially the same function and structure are denoted with the same reference numerals, and repeated explanation of these structural elements is omitted.

[1.1. Outline of Three-Dimensional Shape Forming System]
First, an outline of a three-dimensional shape forming system according to a first embodiment of the present disclosure will be described with reference to
As shown in
The information processing apparatus 11 generates shape information indicating a shape of the three-dimensional-shaped object 2 formed by the printer apparatus 12. Specifically, the information processing apparatus 11 first generates shape information indicating a shape of the three-dimensional-shaped object 2 in which at least a part thereof has a three-dimensional mesh-like structure on the basis of outer shape information indicating an outer shape of the three-dimensional-shaped object 2 that is, for example, input by a user. Further, the generated shape information is divided into pieces for a plurality of layers in a vertical direction, and the piece thereof for each layer is transmitted to the printer apparatus 12.
The printer apparatus 12 is a 3D printer apparatus for forming the three-dimensional-shaped object 2. Specifically, the printer apparatus 12 acquires the shape information of the three-dimensional-shaped object 2 for each layer from the information processing apparatus 11 and forms the three-dimensional-shaped object 2 in each layer. That is, the whole shape of the three-dimensional-shaped object 2 is formed by laminating a shape formed in each layer. Such a method of forming the three-dimensional-shaped object 2 is referred to as “additive manufacturing”.
For example, the printer apparatus 12 may be a 3D printer apparatus using a fused deposition modeling (FDM) method for forming a three-dimensional shape by ejecting and laminating fused resin. Further, the printer apparatus 12 may be a 3D printer apparatus using, for example, a stereolithography for forming a three-dimensional shape by using photocurable resin or the like or a powder method for forming a three-dimensional shape by hardening material powder spread in the form of layer by performing, for example, sintering with a laser or the like or firm fixation using a binder. Furthermore, the printer apparatus 12 may be a 3D printer apparatus using a method of extruding viscous material (silicone resin or the like) from a syringe or the like by using pressure.
Further, the printer apparatus 12 may include a plurality of kinds of printer heads. In this case, the three-dimensional shape forming system 1 can change material to be laminated for each printer head and can therefore form a complicated three-dimensional-shaped object 2 in which various kinds of material are combined.
The rail 13 is a stage or bridge that holds the printer apparatus 12. The rail 13 can move the printer apparatus 12 in a first direction in which the rail 13 is extended, and, in addition, a main body of the rail 13 is movable in a second direction orthogonal to the first direction. With this, the printer apparatus 12 can move to an arbitrary position on a two-dimensional plane in parallel to a horizontal plane.
The three-dimensional-shaped object 2 is a molded product in which plants can be cultivated and is used as a substitute for soil. In order to use the three-dimensional-shaped object 2 as a substitute for soil, it is desirable that the three-dimensional-shaped object 2 (also referred to as “culture medium” in hydroponics) can retain plants and water and air needed to grow the plants, be not extremely acidic or basic and have a stable pH (approximately pH4 to 8), and do not emit chemical substances or the like which have a bad influence on growth of the plants.
In order to satisfy the above-mentioned conditions, the three-dimensional-shaped object 2 is such that a region used to cultivate plants is formed to have a three-dimensional mesh-like structure. Because the three-dimensional mesh-like structure allows a plant to take root and has a large number of holes capable of retaining water and air, the three-dimensional mesh-like structure satisfies the above-mentioned conditions and is a structure suitable to cultivate plants. Note that, in order not to have a bad influence on growth of plants, the three-dimensional-shaped object 2 is preferably made of plastic resin, silicone resin, ceramics, metal, or the like which is chemically stable and whose pH is stable in a neutral region.
The three-dimensional shape forming system 1 according to the present embodiment generates shape information indicating a shape of the three-dimensional-shaped object 2 in which a region where plants are cultivated has a three-dimensional mesh-like structure on the basis of outer shape information indicating an outer shape of the three-dimensional-shaped object 2 and forms the three-dimensional-shaped object 2 on the basis of the shape information. With this, the three-dimensional shape forming system 1 can form the three-dimensional-shaped object 2 that has an arbitrary outer shape and is suitable to cultivate plants.
Note that, although

Next, a configuration example of the three-dimensional shape forming system 1 according to the present embodiment will be described with reference to
As shown in
(Configuration of Design Preparing Apparatus)
The designing unit 100 generates outer shape information indicating an outer shape of the three-dimensional-shaped object 2 and vegetation information regarding arrangement of plants to be cultivated in the three-dimensional-shaped object 2 on the basis of input by the user. Specifically, the designing unit 100 generates outer shape information indicating an outer shape of the three-dimensional-shaped object 2 and vegetation information regarding arrangement of plants to be cultivated in the three-dimensional-shaped object 2 on the basis of input by the user via an input unit (not shown) provided in the design preparing apparatus 10. For example, various devices, such as a mouse, a keyboard, a touchscreen, and a sensor for sensing input operation of the user, can be used as the input unit (not shown). Further, a form of the three-dimensional-shaped object 2 indicated by the outer shape information and the vegetation information generated by the designing unit 100 is displayed on a display unit (not shown) provided in the design preparing apparatus 10. For example, a liquid crystal display device, an organic EL (electroluminescence) display device, or the like can be used as the display unit (not shown). With this, the user can design an outer shape of the three-dimensional-shaped object 2 and arrangement of plants while checking a form of the three-dimensional-shaped object 2 to be formed.
Herein, an input screen for designing the three-dimensional-shaped object 2, which is displayed on the display unit of the design preparing apparatus 10, will be described with reference to
An input screen 300 shown in
Note that an icon group 301 for selecting various tools that assist input of the object 400 may be provided in the input screen 300. The various tools that assist input of the object 400 may include, for example, a tool for generating an object having a basic three-dimensional shape such as a quadrangular prism and a column and a tool for changing a shape of a part of an input object, stretching the part thereof, or increasing and reducing a size of the part thereof. The various tools may also include an extruding tool for giving a volume to an arbitrary two-dimensional shape by drawing the two-dimensional shape and extruding the drawn two-dimensional shape. Note that the various tools that assist input of the object 400 are not limited to the above tools, and any tool can be used as long as the tool is a tool used in a publicly-known 3D modeling software or the like. With such an input screen 300, the user can intuitively design and input an outer shape of the three-dimensional-shaped object 2.
Further, an input screen 310 shown in

As a method of predicting a state after plants are grown, a publicly-known simulation method regarding growth of plants can be used. Further, a general growth image of each plant may be stored in each growing period and a growth image of a plant corresponding to a predicted growing period may be displayed as a predicted image. Note that a growing period of a plant may be arbitrarily designated by the user, such as one month, three months, or one year.

(Configuration of Information Processing Apparatus)
The outer shape information acquiring unit 110 acquires the outer shape information indicating the outer shape of the three-dimensional-shaped object 2. Specifically, the outer shape information acquiring unit 110 is an input interface and accepts input of the outer shape information indicating the outer shape of the three-dimensional-shaped object 2 output from the designing unit 100 of the design preparing apparatus 10. For example, the outer shape information acquiring unit 110 may be a circuit for reading outer shape information from a memory or storage medium storing the outer shape information or may be a wired or wireless external interface such as a universal serial bus (USB) interface, an Ethernet (registered trademark) interface, or an IEEE 802.11 standard interface to which outer shape information is input from the outside. The outer shape information is, for example, information indicating an outer shape of an arbitrary three-dimensional-shaped object input by the user. Such outer shape information is preferably generated by the above-mentioned designing unit 100 with reference to
The vegetation information acquiring unit 120 acquires the vegetation information regarding plants to be cultivated in the three-dimensional-shaped object 2. Specifically, the vegetation information acquiring unit 120 is an input interface and accepts input of the vegetation information regarding plants to be cultivated in the three-dimensional-shaped object 2 output from the designing unit 100 of the design preparing apparatus 10. For example, the vegetation information acquiring unit 120, as well as the outer shape information acquiring unit 110, may be a circuit for reading vegetation information from a memory or storage medium or may be a wired or wireless external interface such as a USB interface, an Ethernet (registered trademark) interface, or an IEEE 802.11 standard interface to which vegetation information is input from the outside. The vegetation information includes, for example, information regarding the kind of plants to be cultivated in the three-dimensional-shaped object 2, a region where the plants are cultivated, and arrangement thereof. Further, the vegetation information may include information regarding positions at which seeds of the plants to be cultivated in the three-dimensional-shaped object 2 are sown. Such vegetation information is preferably generated by the above-mentioned designing unit 100 with reference to
Based on the outer shape information indicating the outer shape of the three-dimensional-shaped object 2, the shape information generating unit 130 generates shape information indicating a shape of the three-dimensional-shaped object 2 in which at least a part of a region has a three-dimensional mesh-like structure. Specifically, the shape information generating unit 130 generates shape information indicating a shape of the three-dimensional-shaped object 2 that has an outer shape indicated by the outer shape information acquired by the outer shape information acquiring unit 110 and in which a region where plants are cultivated has a three-dimensional mesh-like structure. That is, the shape information generating unit 130 generates shape information indicating a shape of the three-dimensional-shaped object 2 by converting a region in the three-dimensional-shaped object 2, the region being a region where plants are cultivated, into a three-dimensional mesh-like structure that satisfies the conditions suitable for a growth environment of plants.
Herein, mesh of the three-dimensional mesh-like structure may have any shape and may have any one of, for example, a triangular shape, a rectangular shape, a hexagonal shape, and a circular shape. Further, the mesh of the three-dimensional mesh-like structure may have a plurality of shapes in combination or may have random shapes.
Further, a size of the mesh of the three-dimensional mesh-like structure is preferably set on the basis of the kind of plant to be cultivated in a region of the three-dimensional mesh-like structure. In a case where the mesh of the three-dimensional mesh-like structure is extremely smaller than a root of a plant to be cultivated, there is a possibility that the plant to be cultivated cannot satisfactorily take root in the three-dimensional mesh-like structure. Further, in a case where the mesh of the three-dimensional mesh-like structure is extremely larger than a root of a plant to be cultivated, there is a possibility that the plant to be cultivated cannot satisfactorily absorb moisture and nourishment from the root in the three-dimensional mesh-like structure. Furthermore, in a case where the mesh of the three-dimensional mesh-like structure is extremely larger than a seed of a plant to be cultivated, there is a possibility that the seed of the plant is not held in three-dimensional mesh-like structure. Therefore, the size of the mesh of the three-dimensional mesh-like structure is preferably set on the basis of a size of at least one of a root and a seed of a plant to be cultivated in the region of the three-dimensional mesh-like structure.
Specifically, the size of the mesh of the three-dimensional mesh-like structure is preferably from 0.1 mm to several mm. For example, in a case where a plant to be cultivated is herbs, the size of the mesh of the three-dimensional mesh-like structure is preferably from 0.2 mm to 1 mm, and, in a case where a plant to be cultivated is tomato or the like, the size of the mesh of the three-dimensional mesh-like structure is preferably from 2 mm to 3 mm. Further, in a case where a plant to be cultivated is watermelon or the like, the size of the mesh of the three-dimensional mesh-like structure is preferably from 4 mm to 6 mm.
Further, the shape information generating unit 130 may form a pit (i.e., hollow or depression) at a position at which a seed of a plant is sown in the three-dimensional mesh-like structure of the three-dimensional-shaped object 2. For example, in a case where a seed of a plant is sown in an inclined part of the three-dimensional-shaped object 2, there is a possibility that the seed of the plant rolls and moves from a position at which the seed has been sown. Therefore, the shape information generating unit 130 preferably forms a pit having a size at which a seed to be sown can be received at a position at which the seed is sown in the three-dimensional mesh-like structure.
Note that information regarding the kind of plant to be cultivated in the three-dimensional-shaped object 2 and information regarding a position at which a seed of a plant is sown may be acquired by, for example, the vegetation information acquiring unit 120 as vegetation information. Further, information regarding sizes of a seed and a root of a plant may be acquired from, for example, the plant information storage unit 140.
The plant information storage unit 140 stores information regarding plants. Specifically, the plant information storage unit 140 may store information regarding sizes of a seed and a root of a plant and may store information for predicting a growth state of a plant and information regarding appropriate denseness of a plant for setting optimal sowing positions of seeds of the plant.
Note that the plant information storage unit 140 may be provided inside the information processing apparatus 11 or may be provided outside the information processing apparatus 11. In a case where the plant information storage unit 140 is provided outside the information processing apparatus 11, the information processing apparatus 11 may acquire information regarding plants from the plant information storage unit 140 via a network or the like.
The layer dividing unit 150 divides the shape of the three-dimensional-shaped object 2 into a plurality of layers laminated in the vertical direction and generates shape information of each layer. Specifically, the layer dividing unit 150 divides the shape of the three-dimensional-shaped object 2 indicated by the shape information generated by the shape information generating unit 130 into a plurality of layers laminated in the vertical direction and generates shape information indicating a shape of each of the divided layers.
The output unit 160 outputs the shape information indicating the shape of each layer of the three-dimensional-shaped object 2. Specifically, the output unit 160 is an output interface and outputs the shape information indicating the shape of each of the plurality of layers divided by the layer dividing unit 150 to the three-dimensional shape forming unit 170. Further, the output unit 160 may output the vegetation information of the three-dimensional-shaped object 2 acquired by the vegetation information acquiring unit 120 to the seed sowing unit 180. For example, the output unit 160 may be a circuit for outputting information from a memory or storage medium or may be a wired or wireless external interface such as USB interface, an Ethernet (registered trademark) interface, or an IEEE 802.11 standard interface for outputting information to the outside.
In the three-dimensional shape forming system 1, the three-dimensional shape forming unit 170 forms the three-dimensional-shaped object 2 as a laminated body of a plurality of layers laminated in the vertical direction by using additive manufacturing. Therefore, the layer dividing unit 150 converts the shape information generated by the shape information generating unit 130 into pieces of shape information of the respective divided layers, thereby allowing the three-dimensional shape forming unit 170 to form the three-dimensional-shaped object 2. Software having such a function of the layer dividing unit 150 is generally referred to as “slicing software” in some cases.
Note that the layer dividing unit 150 may be provided in the printer apparatus 12 instead of the information processing apparatus 11. In such a case, the output unit 160 may output, to the layer dividing unit 150, the outer shape information indicating the outer shape of the three-dimensional-shaped object 2 generated by the shape information generating unit 130.
(Configuration of Printer Apparatus)
The three-dimensional shape forming unit 170 forms the three-dimensional-shaped object 2 by using additive manufacturing. Specifically, the three-dimensional shape forming unit 170 accepts input of the shape information of the three-dimensional-shaped object 2 in each layer divided by the layer dividing unit 150 from the output unit 160 and forms the three-dimensional-shaped object 2 in each layer on the basis of the shape information. For example, the three-dimensional shape forming unit 170 may be a 3D printer head that is provided in the printer apparatus 12 and forms the three-dimensional-shaped object 2.
Herein, a method in which the three-dimensional shape forming unit 170 forms the three-dimensional-shaped object 2 is not particularly limited as long as the method is a kind of additive manufacturing. For example, the three-dimensional shape forming unit 170 may form the three-dimensional-shaped object 2 by using, for example, a fused deposition modeling (FDM) method for forming a three-dimensional shape by ejecting and laminating fused resin, a stereolithography for forming a three-dimensional shape by using photocurable resin, a powder method for forming a three-dimensional shape by hardening material powder spread in the form of layer by performing, for example, sintering with a laser or the like or firm fixation using a binder, or a method for forming a three-dimensional shape by extruding viscous material from a syringe.
Further, as material from which the three-dimensional-shaped object 2 is made, any material can be used as long as the material is material from which the three-dimensional shape forming unit 170 can form the three-dimensional-shaped object 2 by using additive manufacturing. Specifically, the three-dimensional-shaped object 2 may be formed by using plastic resin, silicone resin, ceramic, metal, and the like. Ceramic is preferably sintered. Note that the three-dimensional-shaped object 2 is used to cultivate plants, and therefore, in order to improve a water retention capacity, material such as ceramic having a porous surface may be used as material from which the three-dimensional-shaped object 2 is made.
For example, in a case where the three-dimensional-shaped object 2 is formed by using the fused deposition modeling method, thermoplastic resin such as acrylonitrile-butadiene-styrene resin (ABS resin), polylactic resin (PLA resin), and polycarbonate resin can be suitably used as material. Further, those thermoplastic resins may be mixed with impurities such as chips of wood. Further, in a case where the three-dimensional-shaped object 2 is formed by using the stereolithography, ultraviolet curable resin such as acrylic resin and epoxy resin can be suitably used as material. Further, in a case where the three-dimensional-shaped object 2 is formed by using the powder method, organic resin such as nylon and metal such as bronze, steel, nickel, and titanium can be suitably used as material. Furthermore, in a case where the three-dimensional-shaped object 2 is formed by extruding viscous material from a syringe, silicone resin and the like can be suitably used as material.
The seed sowing unit 180 sows seeds of plants in the formed three-dimensional-shaped object 2. Specifically, the seed sowing unit 180 accepts input of the vegetation information of the three-dimensional-shaped object 2 from the output unit 160 and, on the basis of sowing positions of seeds included in the vegetation information, sows the seeds of plants at the respective sowing positions. For example, the seed sowing unit 180 may be a 3D printer head that is provided in the printer apparatus 12 and sows seeds of plants in the three-dimensional-shaped object 2.
Herein, the seed sowing unit 180 may be configured as any mechanism as long as the seed sowing unit 180 can store a plurality of kinds of seeds and selectively sow the seeds. For example, the seed sowing unit 180 may sow seeds in the three-dimensional-shaped object 2 by including a plurality of seed storage chambers and having a mechanism for selectively dropping seeds of a particular kind of plant on the three-dimensional-shaped object 2 from the seed storage chambers.
Further, the seed sowing unit 180 may sow seeds of a plant in the form of a mixture with gelled material capable of retaining moisture. Specifically, the seed sowing unit 180 may be a syringe filled with a mixture of gelled material and seeds of a plant and sow the seeds of the plant in the three-dimensional-shaped object 2 by injecting the mixture into the three-dimensional-shaped object 2. With this, it is possible to orient moisture around the seeds by using the gelled material and regularly supply moisture to the seeds, and therefore it is possible to improve a germination rate of the sown seeds. Note that, as the gelled material capable of retaining moisture, for example, sodium alginate that is mainly contained in seaweed and the like and a water-absorbing polymer can be exemplified.
A mixing ratio of gelled material to seeds of a plant to be sown can be set on the basis of the kind of seeds, a structure of the three-dimensional-shaped object 2, and the kind of forming material. In such a case, the information processing apparatus 11 further includes a mixing-ratio calculation unit, and the mixing-ratio calculation unit may automatically calculate a mixing ratio of gelled material to seeds of a plant to be sown on the basis of information regarding the three-dimensional-shaped object 2 to be formed and information regarding the plant to be sown in the three-dimensional-shaped object 2.
For example, in a case where the seeds to be sown are basil or the like which takes time to germinate or in a case where a water retention capacity of the three-dimensional-shaped object 2 is low, the mixing-ratio calculation unit may calculate the mixing ratio so that a proportion of the gelled material to be mixed with the seeds is increased. With this, it is possible to reduce a possibility that supply of moisture from the gelled material is stopped and the seeds dry before the sown seeds germinate. Further, in a case where the seeds to be sown are arugula or the like which soon germinates or in a case where the water retention capacity of the three-dimensional-shaped object 2 is high, the mixing-ratio calculation unit may calculate the mixing ratio so that a proportion of the gelled material to be mixed with the seeds is reduced. With this, it is possible to reduce a possibility that the germinated seeds are undeveloped because the germinated seeds move in the gelled material and a possibility that the seeds move from sowing positions thereof.
For example, in a case where a position at which a seed is sown in the three-dimensional-shaped object 2 is inclined, the gelled material tends to flow along inclination. Therefore, the mixing-ratio calculation unit may calculate the mixing ratio so that a proportion of the gelled material to be mixed with the seed is increased in consideration of a flowing amount of the gelled material. Further, in a case where a position at which a seed is sown in the three-dimensional-shaped object 2 is flat, the gelled material does not flow, and therefore the mixing-ratio calculation unit may calculate the mixing ratio so that a proportion of the gelled material to be mixed with the seed is reduced.
In a case where a mixing ratio of gelled material to seeds of a plant to be sown is controlled, the seed sowing unit 180 may include a plurality of syringes filled with respective seeds different from each other and a syringe filled with gelled material. In such a case, by controlling injection amounts of the respective syringes filled with the seeds and the syringe filled with the gelled material, the seed sowing unit 180 can change the mixing ratio in a mixture of the gelled material and the seeds for each kind of seed and in each region of the three-dimensional-shaped object 2.
Further, in a case where the mixing-ratio calculation unit of the information processing apparatus 11 automatically calculates a mixing ratio of gelled material to seeds of a plant to be sown, the information processing apparatus 11 outputs vegetation information including mixing ratio information regarding the mixing ratio of the seeds to the gelled material from the output unit 160. By controlling the syringe filled with the seeds and the syringe filled with the gelled material on the basis of the mixing ratio information included in the output vegetation information, the seed sowing unit 180 can sow the seeds in accordance with the mixing ratio calculated in the information processing apparatus 11.
With the above configuration, the three-dimensional shape forming system 1 according to the present embodiment can form the three-dimensional-shaped object 2 that has an arbitrary outer shape that is, for example, input by the user and is used to cultivate plants. Further, the three-dimensional shape forming system 1 can sow seeds of plants in the formed three-dimensional-shaped object 2 and cultivate the plants on the three-dimensional-shaped object 2.
A three-dimensional-shaped object formed by such a three-dimensional shape forming system 1 according to the present embodiment will be specifically described with reference to
As shown in
Further, a plurality of pits 211 for receiving seeds at positions at which the seeds of a plant are sown may be provided in the three-dimensional-shaped object 210. With this configuration, the three-dimensional-shaped object 210 can prevent the seeds from rolling and moving along inclination from the positions at which the seeds have been sown.
Further, a three-dimensional-shaped object formed by the three-dimensional shape forming system 1 according to the present embodiment may form a landscape of, for example, a garden in which plants are cultivated in a part of a region and landscape components such as a pond and a rock are arranged in a part of the region. The three-dimensional-shaped object 2 in which such landscape components are arranged can also be designed by the designing unit 100.
Such a three-dimensional-shaped object will be specifically described with reference to
Note that the landscape components are inorganic substances other than plants, water sources, artificial objects, and the like forming a landscape in a garden or the like. For example, the landscape components are inorganic substances such as a stone, a rock, and a mountain, water sources such as a river and a pond, and artificial objects such as a bridge, a shed, a bench, a garden lantern, and a fence.
For example, an input screen 340 shown in

Specifically, as shown in
With such a configuration, the three-dimensional shape forming system 1 can form a three-dimensional-shaped object having a landscape of a garden in which plants are cultivated in a part of a region and a bridge, a garden lantern, a rocky area, and the like are assembled in a part of the region. Further, the three-dimensional shape forming system 1 can form, as a three-dimensional-shaped object, furniture that looks as if a garden is embedded in appearance by cultivating plants in a part of a region of a chair, a table, and the like. Furthermore, the three-dimensional shape forming system 1 can also form a pipeline that is a path of water inside the non-cultivated region and can therefore form a three-dimensional-shaped object in which, by injecting water into a predetermined place, the injected water automatically spreads all over the whole three-dimensional-shaped object.

Next, the generated shape information of each layer is output to the three-dimensional shape forming unit 170 by the output unit 160, and the three-dimensional shape forming unit 170 forms the three-dimensional-shaped object on the basis of the shape information of each layer by using additive manufacturing (S140). For example, as shown in
With such operation as described above, the three-dimensional shape forming system 1 according to the present embodiment can form a three-dimensional-shaped object that has an arbitrary outer shape and is used to cultivate plants. Further, by sowing seeds of plants in the formed three-dimensional-shaped object, the three-dimensional shape forming system 1 can cultivate the plants in the three-dimensional-shaped object.

Note that the three-dimensional shape forming apparatus 1A may be made up of a plurality of pieces of hardware. For example, the three-dimensional shape forming apparatus 1A may be made up of an information processing apparatus including the outer shape information acquiring unit 110, the vegetation information acquiring unit 120, the shape information generating unit 130, the plant information storage unit 140, and the layer dividing unit 150 and a printer apparatus including the three-dimensional shape forming unit 170, the resin injecting unit 191, and the seed sowing unit 180.
The three-dimensional shape forming apparatus 1A according to the present embodiment is different from the three-dimensional shape forming system 1 according to the first embodiment in that the three-dimensional shape forming apparatus 1A further includes the resin injecting unit 191. Hereinafter, a characteristic configuration of the three-dimensional shape forming apparatus 1A according to the present embodiment will be described, and description of a configuration substantially similar to that of the three-dimensional shape forming system 1 according to the first embodiment will be omitted.
The resin injecting unit 191 injects unfoamed foamable resin into the three-dimensional mesh-like structure of the three-dimensional-shaped object 2. Note that the injected foamable resin foams in the three-dimensional mesh-like structure. For example, the resin injecting unit 191 may be a 3D printer head that injects foamable resin into the three-dimensional mesh-like structure. Note that the foamable resin is preferably, for example, resin whose raw material is polyurethane resin, polystyrene resin, polyethylene resin, polypropylene resin, or the like and to which foamability is applied by generating a gas phase in the resin by vaporization of a low-boiling-point solvent or chemical reaction. Specifically, the foamable resin is preferably flexible polyurethane foam or the like.
Because the inside of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 formed by the three-dimensional shape forming apparatus 1A according to the present embodiment is filled with foamable resin, it is possible to improve the water retention capacity, as compared with the three-dimensional-shaped object 2 having only the three-dimensional mesh-like structure. Therefore, the three-dimensional shape forming apparatus 1A according to the present embodiment can form the three-dimensional-shaped object 2 that has an arbitrary outer shape, has a high water retention capacity, and is more suitable to cultivate plants. In particular, because foamable resin has a large number of pores inside and has high elasticity and therefore has a high water retention capacity, the foamable resin is preferable as material with which the inside of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 used to cultivate plants is filled.
Herein, in the present embodiment, the size of the mesh of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 may be an arbitrary size. This is because, in the present embodiment, a root and a seed of a plant is held by foamable resin and therefore the size of the mesh of the three-dimensional mesh-like structure does not need to be set on the basis of the kind of plant. Further, in the present embodiment, a pit does not need to be formed at a position at which a seed of a plant is sown in the three-dimensional mesh-like structure of the three-dimensional-shaped object 2. This is because, in the present embodiment, even in a case where a seed of a plant is sown in an inclined part of the three-dimensional-shaped object 2, the seed of the plant is held by foamable resin and the sown seed does not easily roll and move.
However, in the present embodiment, the size of the mesh of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 is preferably such that a size of mesh on a surface of the three-dimensional mesh-like structure is smaller than a size of mesh thereinside. This is because, by reducing the size of the mesh on the surface of the three-dimensional mesh-like structure, foamable resin is kept inside the three-dimensional-shaped object 2 and the foamable resin is prevented from foaming to have a shape greatly deviating from the outer shape of the three-dimensional-shaped object 2.

A method in which such a three-dimensional shape forming apparatus 1A according to the present embodiment forms a three-dimensional-shaped object will be specifically described with reference to

In
Further, as shown in
As described above, the three-dimensional shape forming apparatus 1A according to the present embodiment can form the three-dimensional-shaped object 2 that has an arbitrary outer shape, has a high water retention capacity because of foamable resin, and is more suitable to cultivate plants.
[3.1. Configuration Example of Three-Dimensional Shape Forming System]
Then, a three-dimensional shape forming system according to a third embodiment of the present disclosure will be described with reference to
As shown in
Note that the three-dimensional shape forming apparatus 1B may be made up of a plurality of pieces of hardware. For example, the three-dimensional shape forming apparatus 1B may be made up of an information processing apparatus including the outer shape information acquiring unit 110, the vegetation information acquiring unit 120, the shape information generating unit 130, the plant information storage unit 140, and the layer dividing unit 150 and a printer apparatus including the three-dimensional shape forming unit 170, the solid matter filling unit 192, and the seed sowing unit 180.
The three-dimensional shape forming apparatus 1B according to the present embodiment is different from the three-dimensional shape forming system 1 according to the first embodiment in that the three-dimensional shape forming apparatus 1B further includes the solid matter filling unit 192. Hereinafter, a characteristic configuration of the three-dimensional shape forming apparatus 1B according to the present embodiment will be described, and description of a configuration substantially similar to that of the three-dimensional shape forming system 1 according to the first embodiment will be omitted.
The solid matter filling unit 192 fills the inside of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 with water-retention solid matter. For example, the solid matter filling unit 192 may be a 3D printer head that feeds water-retention solid matter to the three-dimensional mesh-like structure. Herein, the water-retention solid matter is solid matter capable of retaining water and is specifically porous solid matter such as a pumice stone, baked clay, ceramic, or silica gel. For example, the water-retention solid matter may be expanded clay (so-called hydroballs) or the like obtained by expanding and baking granular clay at a high temperature.
Note that the water-retention solid matter is preferably matter whose volume is not changed by absorbing water. This is because, in the present embodiment, the inside of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 is filled with the water-retention solid matter, and therefore, in a case where a volume of the water-retention solid matter is extremely increased by absorbing water, there is a possibility that the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 is broken by the increased water-retention solid matter.
Because the inside of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 formed by the three-dimensional shape forming apparatus 1B according to the present embodiment is filled with the water-retention solid matter, it is possible to improve the water retention capacity, as compared with the three-dimensional-shaped object 2 having only the three-dimensional mesh-like structure. Therefore, the three-dimensional shape forming apparatus 1B according to the present embodiment can form the three-dimensional-shaped object 2 that has an arbitrary outer shape, has a high water retention capacity, and is more suitable to cultivate plants.
In the present embodiment, a pit may be formed at a position at which a seed of a plant is sown in the three-dimensional mesh-like structure of the three-dimensional-shaped object 2. In a case where a seed of a plant is sown in an inclined part of the three-dimensional-shaped object 2, there is a possibility that the seed of the plant rolls and moves from a position at which the seed has been sown. Therefore, by forming a pit at a position at which a seed of a plant is sown, the seed of the plant is received in the pit, which prevents the seed of the plant from rolling and moving. Further, a size of mesh of the three-dimensional mesh-like structure in the pit is preferably smaller than a size of a seed of a plant to be sown. This is because, in a case where the mesh of the three-dimensional mesh-like structure is larger than the seed of the plant, there is a possibility that the seed of the plant is not held in the three-dimensional mesh-like structure.
Further, in the present embodiment, a size of mesh on a surface of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 is preferably smaller than a size of the water-retention solid matter with which the inside of the three-dimensional mesh-like structure is filled. By reducing the size of the mesh on the surface of the three-dimensional mesh-like structure so that the size thereof is smaller than the size of the water-retention solid matter, it is possible to prevent the water-retention solid matter from leaking out of the three-dimensional-shaped object 2. Furthermore, a size of mesh inside the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 is preferably larger than the size of the mesh on the surface. This is to fill the inside of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2 with a greater amount of the water-retention solid matter.
Note that, in order to fill the inside of the three-dimensional mesh-like structure with the water-retention solid matter, at least one or more openings larger than the size of the water-retention solid matter are preferably provided in an upper part of the three-dimensional mesh-like structure of the three-dimensional-shaped object 2.

For example, the storage device 919 may function as the plant information storage unit 140.
The drive 921 is a reader/writer for a storage medium. The drive 921 reads information stored on a removable storage medium inserted into the drive 921, such as a semiconductor memory, and outputs the information to the RAM 905.
