Method for building a three dimensional object

1. A method for building a three-dimensional object, the method comprising:

dispensing, layer by layer, an interface material from nozzles of a print head to form a lower part of the three-dimensional object, the lower part having a recess;

curing the interface material;

inserting an insert into the recess; and

dispensing additional interface material, layer by layer, on the lower part and the insert to form an upper part of the three-dimensional object.

2. The method of claim 1 , wherein said interface material comprises a building material.

3. The method of claim 1 , wherein said interface material comprises a building material and a support material.

4. The method of claim 1 comprising:

removing remnants of uncured interface material prior to inserting the insert into the recess.

5. The method of claim 1 , wherein the recess is larger than the insert and further comprising:

after inserting the insert into the recess, dispensing interface material onto the recess to fill gaps between cured material and the insert.

6. The method of claim 1 comprising:

dispensing a support material to form at least a portion of a support structure for supporting the three-dimensional object.

7. The method of claim 1 , wherein the insert is rigid, semi-rigid or flexible.

8. The method of claim 1 , wherein the insert is made of an insert material different than the interface material.

9. The method of claim 8 , wherein the insert material is more rigid than the interface material after the interface material is cured.

10. The method of claim 1 , wherein the insert includes plastic.

11. The method of claim 1 , wherein the insert includes metal.

12. The method of claim 1 , wherein the insert includes wood.

13. The method of claim 1 , wherein the insert is a plate shaped member.

14. The method of claim 1 , wherein the insert is a skewed member.

15. The method of claim 1 , wherein the insert includes threads.

16. A method for building a three-dimensional object, the method comprising:

dispensing, layer by layer, an interface material from nozzles of a print head to form a lower part of the three-dimensional object, the lower part having a recess;

inserting an insert into the recess; and

dispensing additional interface material, layer by layer, on the lower part and the insert to form an upper part of the three-dimensional object;

dispensing a support material to form at least a portion of a support structure for supporting the three-dimensional object, the support structure comprises at least one pillar of building material surrounded by the support material.
