Model of the Selective Laser Melting Process-Powder Deposition Models in Multistage Multi-Material Simulations

This paper presents one of the final stages in development a holistic model selective laser melting (SLM) process. The developed previously allows for modeling only stage SLM, which limits simulations to cycle with material. lattice Boltzmann method is applied simulation treatment, melting, fluid flow, and solidification. Several models powder bed generation were within framework are described this paper. They on basis static dynamic physical principles use cellular automata, their own code, Unity® platform. employed continuous discrete particle representation incorporated deposition particles atomized or arbitrary shape. closing external circuit, contains model, initialization, its realization by based Lattice Method (LBM), removal us finish treatment initialize next, thereby enabling multistage multi-material simulations. results SLM process Ti-6Al-V alloy bioactive glass presented These confirm possibility several two different materials. can be used simulation, design, optimization multistage, processes.
