Abstract

A system and methods for solid freeform fabrication of an object is disclosed. The system comprises a solid freeform fabrication apparatus having a plurality of dispensing heads, a building material supply apparatus configured to supply a plurality of building materials to the fabrication apparatus, and a control unit configured for controlling the fabrication apparatus and the supply apparatus based on an operation mode selected from a plurality of predetermined operation modes.

Claims (19)

1. A method of solid freeform fabrication, comprising:

dispensing a modeling material, a support material, and at least one additional material that cannot function as a modeling material and cannot function as a support material on its own,

at least partially solidifying said modeling material, such as to form a three-dimensional object, and

removing said at least one additional material to form a porous or hollow three-dimensional object.

2. The method of claim 1 , wherein said at least one additional material is at least partially interlaced with said modeling material, and wherein said removing forms a porous three-dimensional object.

3. The method according to claim 1 , wherein said at least partially solidifying said modeling material is executed such that at least part of said modeling material solidifies and said at least one additional material does not solidify.

4. The method according to claim 3 , wherein said at least one additional material comprises at least one non-solidifiable material.

5. The method according to claim 1 , wherein said at least one additional material comprises at least one non-solidifiable material.

6. The method according to claim 1 , wherein during said at least partial solidification, said at least one additional material remains in liquid form.

7. The method according to claim 1 , wherein during said at least partial solidification, said at least one additional material remains in a gel form.

8. The method according to claim 1 , wherein during said at least partial solidification, said at least one additional material remains in a paste form.

9. The method according to claim 1 , wherein said at least one additional material and said at least one modeling material combine after said dispensing to form a solidifiable mixture.

10. The method according to claim 1 , wherein said at least one additional material comprises at least two additional materials.

11. The method of claim 10 , wherein said at least two additional materials are non-solidifiable materials that combine after said dispensing to form a solidifiable mixture.

12. The method of claim 1 , wherein said removing is by draining.

13. The method of claim 1 , wherein said removing is by burning.

14. A method of solid freeform fabrication, comprising:

dispensing at least two non-solidifiable materials that that combine after said dispensing to form a solidifiable mixture, and

at least partially solidifying said solidifiable mixture, such as to form a three-dimensional object.
