Three-dimensional numerical simulation of selective laser melting process based on SPH method

Selective laser melting (SLM) is an advanced, efficient and capable manufacturing technology that utilizes a laser for heating metal or alloy powders to melt and solidify directly into metal parts. In this paper, the smoothed particle hydrodynamics (SPH) method was employed for the three-dimensional numerical simulation of the SLM process. This method is significantly benefit for solving free surface flows and complex motions at multiple...
