Abstract

Methods and systems of and for using volumetric display technology including volumetric display technology to create three-dimensional objects for various industries, including, but not limited to solar, automotive and/or other technological areas that use 3D printing or additive manufacturing.

Claims (44)

1. A method for producing three-dimensional objects, the method comprising:

providing a system comprising

at least three photonic energy emitters, wherein at least one of the at least three photonic energy emitters is a DLP projector,

a flood and drain system having a chamber system, and

a build platform;

providing photonic energy curable material;

projecting a 3D image using the at least three photonic energy emitters onto the build platform;

flooding the photonic energy curable material into the chamber system, wherein the build platform is within the chamber system;

draining the photonic energy curable material away from the chamber system while curing the photonic energy curable material in the shape of the 3D image at a convergence point; and

cryogenic cooling the photonic energy curable material prior to the step of flooding the photonic energy curable material into the chamber system, wherein the cryogenic cooling speeds up the curing of the photonic energy curable material;

wherein one of the at least three photonic energy emitters alone is of insufficient wattage or power to cure or solidify the photo-reactive material, thus, allowing a beam or vector to pass through the photopolymer material,

wherein the photonic energy curable material intersected by the photonic energy emitted by at least two of the at least three photonic energy emitters cures the photonic energy curable material to produce a three-dimensional object at the convergence point, such that the combined wattage or power of the beams or vectors becomes sufficient to cure or solidify the photopolymer material, and

wherein the step of projecting the 3D image using the least three photonic energy emitters onto the build platform occurs prior to the step of flooding the photonic energy curable material into the chamber system,

wherein the photonic energy curable material is a UV photopolymer.

2. The method of claim 1 , wherein the flood and drain system includes an upper chamber, a pump and a lower chamber, and wherein the photonic energy curable material flows from the lower chamber to flood the upper chamber, and returns to the lower chamber, while a portion of the photonic energy curable material is cured to form the three-dimensional object.

3. The method of claim 1 , wherein the three-dimensional object is configured to be made in sections whereby the at least three photonic energy emitters create various three-dimensional objects that are configured to merge with one another to form a larger three-dimensional object external to the chamber.

4. The method of claim 1 , wherein the cryogenic cooling is performed via Dry Ice or Liquid Nitrogen.

5. The method of claim 1 , further comprising cooling the photonic energy curable material via a freezer or refrigerator.

6. The method of claim 1 , wherein the photonic energy curable material is a UV photopolymer.

7. The method of claim 1 , wherein the photonic energy curable material is cured from an inside first layer to an outside layer.

8. The method of claim 1 , wherein the 3D image projected via the at least three photonic energy emitters uses the combined wattage or power of the three photonic energy emitters to cure the photonic energy curable material.

9. The method of claim 1 , wherein the at least three photonic energy emitters include up to one thousand photonic energy emitters.

10. The method of claim 1 , wherein the at least three photonic energy emitters pulse the 3D image.

11. The method of claim 1 , wherein the at least three photonic energy emitters flash or flicker the 3D image.

12. The method of claim 1 , wherein the three-dimensional object is produced in chunks.

13. The method of claim 1 , wherein the cryogenic cooling means acts as a heat transfer device to remove heat from the system.

14. The method of claim 13 , wherein the chamber system has two hermetically sealed metal layers, such that the cryogenic cooling means is injected into the outer layer.

15. The method of claim 2 , wherein the lower chamber is a reservoir that stores the photonic energy curable material.

16. The method of claim 2 , wherein the chamber system includes an overflow port that returns the photonic energy curable material to the lower chamber.

17. The method of claim 1 , wherein the at least three photonic energy emitters project images via LCD, LED, LCOS, 3d Printed SLM, and/or DLP projector technologies.

18. A method for producing three-dimensional objects, the method comprising:

providing a system comprising

at least three photonic energy emitters, wherein at least one of the at least three photonic energy emitters is a DLP projector,

a flood and drain system having a chamber system, and

a build platform;

providing photonic energy curable material;

projecting a 3D image using the at least three photonic energy emitters onto the build platform;

flooding the photonic energy curable material into the chamber system, wherein the build platform is within the chamber system;

draining the photonic energy curable material away from the chamber system while curing the photonic energy curable material in the shape of the 3D image at a convergence point;

wherein one of the at least three photonic energy emitters alone is of insufficient wattage or power to cure or solidify the photo-reactive material, thus, allowing a beam or vector to pass through the photopolymer material,

wherein the photonic energy curable material intersected by the photonic energy emitted by at least two of the at least three photonic energy emitters cures the photonic energy curable material to produce a three-dimensional object at the convergence point, such that the combined wattage or power of the beams or vectors becomes sufficient to cure or solidify the photopolymer material,

wherein the step of projecting the 3D image using the least three photonic energy emitters onto the build platform occurs after the step of flooding the photonic energy curable material into the chamber system, and

wherein the photonic energy curable material is a UV photopolymer.

19. The method of claim 1 , wherein all three of the at least three photonic energy emitters are DLP projectors.
