Front line recyclables repurposed into 3D printing filaments

The scientists involved in the project believe this advance could improve operational readiness, reduce dependence on outside supply chains and enhance safety.

The team presented their findings this week at the 256th National Meeting & Exposition of the American Chemical Society (ACS).

"Ideally, soldiers wouldn't have to wait for the next supply truck to receive vital equipment," said Nicole Zander, PhD a research chemist at the US Army Research Laboratory (ARL). "Instead, they could basically go into the cafeteria, gather discarded water bottles, milk jugs, cardboard boxes and other recyclable items, then use those materials as feedstocks for 3D printers to make tools, parts and other gadgets."

A number of front-line units are equipped with 3D printers that can produce spare parts and other equipment, but they rely on conventional feedstocks, such as commercially available plastic filaments, that must be requisitioned and be delivered, a process that can take days, weeks or even months.
