Material, geometry and process qualification in Additive Manufacturing has been one of the most challenging topics from its inception. Experimental qualification is the candidate of choice although it offers three major bottlenecks namely cost, scalability of material properties obtained using uniaxial experiments to realistic triaxial material properties and spatiotemporal multiscale access of in-situ and as-built micro-structural information.In order to circumvent some of the above-mentioned issues, experimentally validated simulation tools have been developed at 3DSIM to predict in-process thermal, structural and microstructural evolutions leading to process-geometry-material maps for as-built AM process, part and powder chemistry qualification. In addition, further guidance on stress relief, heat treatments and estimation of anistropic triaxial material properties could be also provided.A 3DSIM case study reflecting current automated qualification capabilities used for fabricating Ti6Al4V alloy will be presented at the talk.
