Additive Manufacturing and Metallic Microstructures (AM3)

The aim of the AM3 challenge is to address the fundamental materials science problems that underlie the transition from traditional manufacturing techniques to additive manufacturing (AM), with a specific focus on metallic alloys, and the relation between process, microstructure and properties. The project covers multiple aspects of the materials science of metals parts produced in strongly out-of-equilibrium conditions. The project combines the expertise of four academic partners at EPFL, EMPA and PSI.
