Numerical investigation and an effective modelling on the Selective Laser Melting (SLM) process with aluminium alloy 6061

The Selective Laser Melting (SLM) fabrication process is complex and it is crucial to understand the phenomena that will occur to better control it. In this paper, an FE model on SLM that considers powder-to-solid transition together with an effective method to achieve volume shrinkage and material...
