316L stainless steel parts were manufactured via selective laser melting in this work. The surface morphology, microstructure, density and mechanical property were characterized. It is found that the surface contains a little amount of oxide and splash with balling effect. Microstructure in low magnification shows features of scan molten tracks and molten pools; microstructure in high magnification depicts very fine crystal under rapid cooling. The tensile strength of as-received samples is 652.12 MPa, with a density of 95.6%. Therefore the gas atomized 316L stainless steel powders could be used in manufacturing high quality parts with complex shapes via selective laser melting method.
