The effects of laser selective melting (SLM) and rolling on the mechanical properties of 316L stainless steel were studied. The morphology and fracture characteristics after impact were characterized by means of an optical microscope (OM) and scanning electron microscope (SEM), Meanwhile, tensile strength, hardness, and impact toughness are characterized. The results show that compared with the roll forming, the 316L stainless steel group formed by laser selective melting has surface holes, cracks and spheroidization, and the grains are smaller, the dimples are smaller and shallower, and the strength and hardness are higher than the roll forming. Plastic toughness is much lower than that of rolling.
