Metal Additive Manufacturing Conference - MAMC 2022

In this talk, two case examples of multi-parameter optimization is described, where parameter sets for multiple features such as surface roughness, downface integrity, mechanical performance or bulk density are optimized simultaneously using compact design of experiment. In the first case, a component with specific requirements on weldability, corrosion resistance and mechanical resistance led to a need for rapid powder manufacturing and printing parameter optimization in stainless steel 310, not typically available on the PBF-LB-market. In another example, the industry needs for simultaneously cheaper components and a more environmentally friendly component resulted in an EUREKA research project, VARETIT, on recycling TiAl6V4 components using grinding as opposed to classical gas atomization. The morphology of this powder is terrible, but it is shown how such a powder feedstock can, using compact design of experiment studies, lead to cost effective components fulfilling component requirements while minimizing the CO2 footprint.
