NASA Awards Grant to Pitt Researchers for Testing of DMLM with Simulation

(DesignNews)  NASA’s Space Technology Research Grants Program recently awarded an “Early Stage Innovations” (ESI) grant to simulation software company ANSYS Inc. , a team of additive manufacturing researchers from the University of Pittsburgh’s Swanson School of Engineering. NASA has provided the Pitt research team with $500,000 over three years based on a proposal entitled, “Prediction of Microstructure Evolution in DMLM (Direct Material Laser Melting) process Inconel 718 with Part Scale Simulation.”
This is to address the concern that additive manufacturing (AM) has remained an out-of-reach challenge for some high-temperature applications, most notably in the aerospace sector. At present, the only way to certify a part created by additive manufacturing for space applications is to perform extensive microstructure and property characterization tests on the parts. The costs and time it takes to complete these tests has made it difficult to use 3D-printing technologies, and have put the process out of reach for some manufacturers.
