TECHNOLOGY TRANSFER OPPORTUNITY: 3D-Printed Composites for High Temperature Uses (LEW-TOPS-145)

NASA’s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses.THE TECHNOLOGY: Innovators at the NASA Glenn Research Center, in collaboration with the University of Louisville and the U.S. Air Force, have 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. The resulting composite part can be subsequently post-cured to prepare for high temperature aerospace applications, offering a 3D-printed composite part that can withstand temperatures over 300 °C. This

is a significant advancement in the state-of-the-art in additive manufacturing polymers, offering an SLS process that requires relatively low melting temperatures and creates composites with high temperature capabilities, enabling 3D-printing of parts with complex geometry for high performance applications.To express interest in this opportunity, please submit a license application through NASA’s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/LEW-TOPS-145If you have any questions, please e-mail NASA’s Technology Transfer Program at Agency-Patent-Licensing@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this beta.SAM.gov notice and your preferred contact information.
