Effects of sub-atmospheric pressure on keyhole dynamics and porosity in products fabricated by selective laser melting
A powder-scale multi-physics model is developed to investigate the keyhole dynamics and porosity in products fabricated by selective laser melting (SLM) under the sub-atmospheric pressure. The effects of the sub-atmospheric pressure on the plume attenuation of the laser beam, vaporization temperatur...
