MML is pioneering new metallurgic and ceramic processes for high-strength, scalable, engineering-relevant feedstock materials for net-shape and 3D-printed metal and ceramic parts. Leveraging first-principles modeling and data informatics, we have pioneered scalable nanoparticle functionalization to spatially control composition and metallic microstructure during laser solidification. We are developing scientific understanding of important solidification dynamics and other relevant metallurgic processes that lead to enhanced strength, fatigue toughness, and thermal stability of 3D-printed metals. We are also developing a deep understanding of the fundamental polymer science and thermophysical processes behind high-performance UV-curable pre-ceramic polymers and their composites. Enhancing the thermophysical stability of these polymer-derived ceramics enables new net-shape ceramic parts that function under extreme conditions.
