Additive manufacturing applications have surged in recent years and have become a crucial method for quick prototyping and creating customized structures. FDM printing in particular is the most popular as it comes with affordable prices, adequate sizes, and easy operation. One major disadvantage of 3D printing is the generation of waste; one example would be the removal of supporting structures after the completion of the print or if a part has not been produced correctly.

In these cases, materials will go directly to waste. This is not environmentally friendly and would dramatically increase the cost to operate the printer.

This project aims to recycle onyx and nylon 6,6 plastic for use in a Markforged printer via shredding, drying, screw extrusion, diameter controlling rollers, and spooling.
