Positrusion Filament Recycling System for ISS, Phase II

Metadata Updated: May 2, 2019

The Positrusion ISS Recycler enables recycling of scrap and waste plastics into high-quality filament for 3D printers to enable sustainable in-situ manufacturing on the ISS and future deep-space manned missions. In order to minimize astronaut time required for recycling, mitigate safety risks, and improve the quality of product relative to conventional filament extrusion methods, Tethers Unlimited, Inc. (TUI) has developed a novel "Positrusion" method for processing plastic pieces into filament. The Phase I effort successfully demonstrated Positrusion recycling of 3D-printed scrap ABS and Ultem materials back into filament, establishing the technology at TRL-4. Moreover, testing demonstrated that Positrusion achieves order-of-magnitude improvement in filament dimensional quality compared to commercially-available filament, which not only will improve the performance and reliability of ISS 3D printers but also make Positrusion competitive in terrestrial commercial applications, such as recycling plastic wastes in the home and office into useful 3D printer feedstock. The Phase II effort will deliver a complete ISS recycler payload system configured as an EXPRESS locker payload, flight qualified and at TRL-6. The Positrusion payload will provide recycling services aboard the ISS with operations that are as simple, safe, and reliable as a microwave oven, enabling astronauts to place scraps in the machine, push a button, and then move on to other duties while the recycler automatically processes the part into spooled filament.
