Abstract

A convergent three-dimensional (3D) additive manufacturing system is disclosed which includes a header, a base, a first dispensing system mounted onto the header, the space between the header and the base adjacent to the first dispensing system defining a first zone, a second dispensing system mounted onto the header, the space between the header and the base adjacent the second dispensing system defining a second zone, the first zone, and the second zone are separated by a screen adapted to prevent contamination across the first and second zones, the first dispensing system carrying raw material for a first product, and the second dispensing system carrying raw material for a second product.

First claim

The invention claimed is:

1. A convergent three-dimensional (3D) manufacturing system, comprising:
a header;
a base;
a first dispensing system mounted onto the header, the space between the header and the base adjacent the first dispensing system defining a first zone;
a second dispensing system mounted onto the header, the space between the header and the base adjacent the second dispensing system defining a second zone, the first zone, and the second zone are separated by a screen adapted to prevent contamination across the first and second zones;
a controller; and
a plurality of detectors in one or both of the first and the second zones, the plurality of detectors adapted to provide information about presence of raw materials from the first dispensing system in the second zone, or presence of raw materials from the second dispensing system in the first zone;
the first dispensing system carrying raw material for a first product, and the second dispensing system carrying raw material for a second product.

2. The convergent 3D manufacturing system of claim 1 , the first dispensing system and the second dispensing system adapted to dispense respective raw material, simultaneously.

3. The convergent 3D manufacturing system of claim 1 , the first dispensing system and the second dispensing system adapted to dispense respective raw material, at different times.

4. The convergent 3D manufacturing system of claim 1 , the controller configured to move i) the base; ii) the header; or iii) a combination of the base and the header.

5. The convergent 3D manufacturing system of claim 4 , the movement of the base is according to movement in i) Cartesian coordinate system; ii) cylindrical coordinate system; or spherical coordinate system.

6. The convergent 3D manufacturing system of claim 1 , the plurality of detectors include optical detectors.

7. The convergent 3D manufacturing system of claim 1 , the plurality of detectors include chemical detectors.

8. The convergent 3D manufacturing system of claim 1 , the first and second dispensing systems each includes a spool containing the respective raw material.

9. The convergent 3D manufacturing system of claim 8 , the two spools are packaged in a concentric spool assembly having an inner spool, and an outer spool.

10. The convergent 3D manufacturing system of claim 9 , wherein the inner spool is adapted to move independently from the outer spool.

11. The convergent 3D manufacturing system of claim 9 , wherein the inner spool defines movement of the outer spool.

12. The convergent 3D manufacturing system of claim 9 , wherein the outer spool defines movement of the inner spool.

13. The convergent 3D manufacturing system of claim 1 , the first and second dispensing system each includes a powder cup with an inlet adapted to receive a solvent.

14. The convergent 3D manufacturing system of claim 1 , further comprising a subtractive manufacturing sub-system adapted to remove unwanted portions of the first or second products.

15. The convergent 3D manufacturing system of claim 1 , further comprising an assembly sub-system adapted to assemble the first or second products with one or more components, thereby generating a system of products.

16. A convergent three-dimensional (3D) manufacturing system, comprising:
a header;
a base;
a first dispensing system mounted onto the header, the space between the header and the base adjacent the first dispensing system defining a first zone,
a second dispensing system mounted onto the header, the space between the header and the base adjacent the second dispensing system defining a second zone, the first zone, and the second zone are separated by a screen adapted to prevent contamination across the first and second zones;
the first dispensing system carrying raw material for a first product, and the second dispensing system carrying raw material for a second product,
wherein the first and second dispensing systems each includes a spool containing the respective raw material, and
wherein the two spools are packaged in a concentric spool assembly having an inner spool, and an outer spool.

17. The convergent 3D manufacturing system of claim 16 , wherein the inner spool is adapted to move independently from the outer spool.

18. The convergent 3D manufacturing system of claim 16 , wherein the inner spool defines movement of the outer spool.

19. The convergent 3D manufacturing system of claim 16 , wherein the outer spool defines movement of the inner spool.

20. The convergent 3D manufacturing system of claim 16 , the first and second dispensing system each includes a powder cup with an inlet adapted to receive a solvent.
