Systems and methods for three dimensional printing using microwave assisted deposition

1. A system comprising:

a reservoir for receiving a thermoset;

a microwave resonance cavity comprising an outer conductor and a tubular or annular inner conductor, said inner conductor comprising a nozzle disposed therein through which the thermoset can pass, said nozzle in fluid communication with said reservoir to receive the thermoset;

a controller comprising a processor and memory, said processor executing instruction to:

cause the thermoset to be transferred from said reservoir to said microwave resonance cavity; and

cause a microwave source to provide microwave energy into said microwave resonance cavity to produce a standing wave at a point of deposition to heat the thermoset after the thermoset exits said microwave resonance cavity, accelerating the chemical reaction and solidifying the thermoset.

2. The system according to claim 1 , further comprising a sensor that detects a temperature of the thermoset that has been heated by said microwave resonance cavity.

3. The system according to claim 2 , wherein said controller is configured to obtain output from said sensor and selectively adjust an operating parameter of said microwave source.

4. The system according to claim 1 , wherein the thermoset comprises a resin.

5. The system according to claim 1 , wherein said system further comprises a connector that couples said outer conductor with said microwave source.

6. The system according to claim 1 , wherein a terminal end of said inner conductor is coplanar with a terminal end of said outer conductor.

7. The system according to claim 1 , further comprising a stabilizing disk that fixes a position of said terminal end of said inner conductor relative to said terminal end of said outer conductor.

8. The system according to claim 1 , further comprising an air supply device for delivering a volume of air into said reservoir to extrude the thermoset.

9. The system according to claim 1 , wherein said nozzle is coplanar with said terminal end of said inner conductor.

10. The system according to claim 1 , wherein said nozzle protrudes beyond said terminal end of said inner conductor and said outer conductor.

11. The system according to claim 1 , wherein said reservoir and microwave resonance cavity are in communication with a 3D printer.

12. The system according to claim 1 , wherein said controller provides instruction to said reservoir and said microwave resonance cavity as the thermoset is cured.

13. The system according to claim 1 , wherein the microwave energy is provided immediately after the thermoset exits said microwave resonance cavity at said point of deposition.

14. The system according to claim 1 , wherein the thermoset comprises a composite.

15. The system according to claim 1 , wherein the thermoset comprises a nanocomposite.

16. The system according to claim 1 , wherein the thermoset comprises a carbonaceous material.

17. The system according to claim 1 , wherein the thermoset further comprises a filler material.

18. The system according to claim 17 , wherein the filler material comprises particles.

19. The system according to claim 17 , where the filler material comprises fibers.

20. The system according to claim 17 , where the filler material comprises carbonaceous nanoparticles (CNP).

21. The system according to claim 17 , where the filler material comprises nanoclay.

22. The system according to claim 17 , where the filler material comprises microballoons.

23. The system according to claim 1 , further comprising a pneumatic for extruding the thermoset.

24. The system according to claim 1 , further comprising a peristaltic pump for extruding the thermoset.
