摘要：
A improved method of additive manufacturing of a recycled granulate is provided. The method comprises providing a starting article. A shredder shreds the starting article to give a shredded product. A granulator shreds the shredded product to give a recycled granulate. The recycled granulate is fed into an additive manufacturing machine. The additive manufacturing machine prints a printed article using the recycled granulate. The method does not comprise a step of compounding the recycled granulate using a twin screw extruder. The starting article, the shredded product, and the recycle granulate each comprise a fiber reinforced polymer composite.
技术问题语段：
The technical issues addressed in this patent text are related to the recycling of composite materials and the production of low-cost, recyclable feedstock for composite applications.
技术功效语段：
The technical efficacy of the patent text is an improved method for additive manufacture and compression molding using a recycled granulate. This method allows for the production of three-dimensional articles and molded articles using recycled granulate, without the need for a twin screw extruder.
权利要求：
CLAIMS
1. A method of additive manufacturing of a recycled granulate, the method comprising the steps of: providing a starting article; shredding the starting article using a shredder to give a shredded product; granulating the shredded product using a granulator to give a recycled granulate; feeding the recycled granulate into an additive manufacturing machine without an intermediate extrusion of the recycled granulate; and printing a printed article from the additive manufacturing machine using the recycled granulate, wherein the starting article, the shredded product, and the recycled granulate each comprise a fiber reinforced polymer composite.
2. The method of claim 1, wherein the fiber reinforced polymer composite is a carbon fiber filled acrylonitrile butadiene styrene (CF-ABS).
3. The method of claim 1, wherein the additive manufacturing machine is a big area additive manufacturing (BAAM) machine.
4. The method of claim 3, wherein the BAAM machine is a BAAM single screw extruder.
5. The method of claim 1, wherein the method does not comprise a step of compounding the recycled granulate.
6. The method of claim 1 , wherein the method does not comprise a step of pelletizing the recycled granulate with a twin screw extruder.
7. The method of claim 1 , wherein the method does not comprise a step of pelletizing the recycled granulate.
8. The method of claim 1 , wherein the starting article is a manufacturing mold.
9. The method of claim 1 , wherein the printed article is a manufacturing mold.
10. A printed article manufactured according to the method of claim 1.
11. A method of compression molding of a recycled granulate, the method comprising the steps of: providing a starting article; shredding the starting article using a shredder to give a shredded product; granulating the shredded product using a granulator to give a recycled granulate; and compression molding a molded article using the recycled granulate without an intermediate extrusion of the recycled granulate; and wherein the starting article, the shredded product, and the recycled granulate each comprise a fiber reinforced polymer composite.
12. The method of claim 11, wherein the fiber reinforced polymer composite is a carbon fiber filled acrylonitrile butadiene styrene (CF-ABS).
13. The method of claim 11, wherein the step of compression molding a molded article is performed using a hydraulic press.
14. The method of claim 11, wherein the method further comprises a step of heating the
recycled granulate.
15. The method of claim 11 , wherein the method does not comprise a step of compounding the recycled granulate.
16. The method of claim 1 , wherein the method does not comprise a step of pelletizing the recycled granulate with a twin screw extruder.
17. The method of claim 11, wherein the method does not comprise a step of pelletizing the recycled granulate.
18. The method of claim 11 , wherein the starting article is a manufacturing mold.
19. The method of claim 11 , wherein the molded article is a manufacturing mold.
20. A molded article manufactured according to the method of claim 11.
