Additive manufacturing (3D printing) is a rapidly growing technology, though, expensive printing filament and wasted material make it less affordable and an unsustainable process. The RePrinter combats these issues by recycling scrap 3D printed plastic parts and household plastics, such as pop bottles, and creates filament for fused deposition modeling (FDM). This product is a fully automated system which grinds, extrudes, and spools the filament for immediate use in FDM. The RePrinter works to control the extrusion speeds and tensions to optimize precise filament dimensions for quality 3D printing, while delivering the product in a timely cost effective manner.
