In this study, 316L stainless steel was fabricated by selective laser melting under different process parameters (375 W–2100 mm·s −1 , 235 W–1400 mm·s −1 , 135 W–750 mm·s −1 ). The solidification microstructure and porosity characteristic of SLM 316L SS samples were researched, and the mechanical an...
