Claims
- 1. A three-dimensional modeling apparatus for fabricating a three-dimensional object by binding a powder material with a binding material, comprising:
a modeling section for forming a body of bound powder material in sequence by applying said binding material to said powder material to bind said powder material, thereby to generate said three-dimensional object; a placement section for mounting of a powder material reservoir containing said powder material; and a powder supply section for supplying said powder material in said powder material reservoir mounted in said placement section to said modeling section.
- 2. The apparatus according to claim 1, wherein
said powder supply section is located above the level of said modeling section.
- 3. The apparatus according to claim 1, wherein
said modeling section includes a supply section for supplying a binding material from above onto said powder material supplied from said powder supply section to represent a predetermined shape.
- 4. A three-dimensional modeling apparatus for fabricating a three-dimensional object by binding a powder material with a binding material, comprising:
a supply section for supplying said powder material; a modeling section for forming a body of bound powder material in sequence by selectively applying said binding material to said powder material supplied from said supply section to bind said powder material, thereby to generate said three-dimensional object; and a removal section for removing an unbound powder material from said three-dimensional object generated in said modeling section, said unbound powder material being said powder material supplied from said supply section but not receiving said binding material.
- 5. The apparatus according to claim 4, further comprising:
a carrier mechanism for carrying said three-dimensional object generated in said modeling section to a position for removal of said unbound powder material in said removal section.
- 6. The apparatus according to claim 4, further comprising:
a post-processing section for performing post-processing on said three-dimensional object after said unbound powder material is removed in said removal section.
- 7. The apparatus according to claim 6, wherein
said post-processing section includes a curing material supply section for applying a curing material to said three-dimensional object, and said post-processing includes a process of impregnating said three-dimensional object with said curing material.
- 8. The apparatus according to claim 7, wherein
said post-processing section further includes an air blower for sending air to said three-dimensional object, and said post-processing further includes a process of drying said curing material used to impregnate said three-dimensional object therewith, by air from said air blower.
- 9. The apparatus according to claim 6, wherein
said three-dimensional object is located in the same position for removal of said unbound powder material in said removal section and for said post-processing in said post-processing section.
- 10. The apparatus according to claim 5, wherein
said three-dimensional object carried by said carrier mechanism is placed on a mesh tray, and said carrier mechanism carries said three-dimensional object by carrying said mesh tray.
- 11. A three-dimensional modeling apparatus for fabricating a three-dimensional object by binding a powder material with a binding material, comprising:
a supply section for supplying said powder material; a modeling section for repeating a process of applying said binding material to said powder material supplied from said supply section to bind said powder material in order to represent each section of said three-dimensional object, thereby to generate said three-dimensional object; and a feed section for recovering and returning an unbound powder material to said supply section, said unbound powder material being said powder material supplied from said supply section but not receiving said binding material.
- 12. The apparatus according to claim 11, wherein
said feed section includes a drying mechanism for drying said powder material recovered.
- 13. The apparatus according to claim 11, wherein
said feed section includes a filter for extracting only said powder material of not more than a predetermined size.
- 14. A three-dimensional modeling method for fabricating a three-dimensional object by binding a powder material with a binding material,
said method using a predetermined apparatus to avoid a user's contact with said powder material, said method comprising the steps of:
(a) placing a mesh tray for use in passing said powder material into a bottom of a box-like modeling space, in such a manner as to support a whole bottom surface of said mesh tray; (b) repeating a process of supplying said powder material flatly in a predetermined thickness in said modeling space and a process of selectively applying said binding material onto said powder material supplied to bind said powder material in order to represent a predetermined shape, thereby to generate on said mesh tray said three-dimensional object bound with said binding material with an unbound powder material remaining therewith; (c) supporting part of said mesh tray above a predetermined space for collecting said unbound powder material; and (d) dropping said unbound powder material into said predetermined space to obtain said three-dimensional object.
- 15. The method according to claim 14, wherein
a first position to support said mesh tray in said step (a) and a second position to support said mesh tray in said step (c) are different, said method further comprising, between said steps (b) and (c), the step of:
moving said mesh tray from said first position to said second position when said mesh tray is loaded with said three-dimensional object bound with said binding material with an unbound powder material remaining therewith.
- 16. The method according to claim 15, further comprising the step of:
after said unbound powder material is dropped off, performing predetermined post-processing on said three-dimensional object at said second position.
- 17. The method according to claim 16, further comprising the step of:
generating another three-dimensional object at said first position while dropping said unbound powder material from said three-dimensional object at said second position, or during said post-processing.
