3D-Printed Composites for High-Temperature Uses

Innovators at NASA Glenn Research Center, in collaboration with the University of Louisville and the U.S. Air Force, developed an additive manufacturing technique to produce composite parts with high-temperature capabilities using thermoset polyimide resins. The process uses selective laser sintering (SLS) to melt-process a powdered version of NASA’s novel RTM370 imide resin filled with finely milled carbon fibers.
