US Army and US Marine Corps Develop Way to Use Waste Plastics on Base for 3D-Printing Feedstock 


Researchers from the U.S. Army Research Laboratory and the U.S. Marine Corps have found a way to use waste plastics, such as water bottles, cardboard and other recyclable materials found on base as starting materials for 3D printing. The driving force for this work is to enhance warfighter capability and readiness by enabling repairs while deployed and to reduce dependence of the logistical supply chain. The team is building a mobile recycling trailer that will enable soldiers to repurpose plastics into feedstocks for 3D printing.

The research by Zander and co-collaborator Capt. Anthony Molnar from the U.S. Marine Corps, generated 3D printing filament from recycled polyethylene terephthalate, or PET, from bottles and plastics without any chemical modifications or additives. PET plastics, found in water and soda bottles, are common waste materials found around bases.
