US military researchers have developed a way to use recycled bottles and other refuse materials to 3D-print replacement parts for soldiers in the field.
Military personnel stationed around the world often have a long wait when they need a critical replacement part. Now, the US Army Research Lab (ARL) and the US Marine Corps have partnered to develop a way to kill two birds with one stone by recycling the plastic bottles and bags the military uses and 3D-printing needed materials in the field.
Nicole Zander, a researcher at ARL, and US Marine Corps Capt. Anthony Molnar are working on a joint project to break down recycled polyethylene terephthalate (PET) plastic into filament to use as a starting material for 3D printers. The material then can be fabricated into plastic parts for radios, canteens, and other items soldiers can use in the field.
