Validated Thermal-Material Simulation to Predict Microstructure Evolution in Selective Laser Melting Additive Manufacturing of Nickel Alloys

Completed TRL 4 (started at 2, targeting 4)

Description

Additive manufacturing (AM) technology has the potential to enable on-demand manufacturing, production of otherwise difficult to manufacture geometries and permit fabrication of ultra lightweight components critical for spaceflight. Integrated methods for microstructure and property prediction of AM components are not currently available but are critical to the realization of desired part design and performance combinations. Our interdisciplinary research team aims to develop, configure and integrate models of material behavior to simulate AM processes and predict properties. These models will be validated using experimental builds.

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
