The principles of selective laser sintering (SLS) were applied in this experiment .The influence of laser power, scan distance, scan speed and other processing parameters of fiber laser on the pore properties, elastic modulus, and micro morphology, etc were investigated in this paper. Tests were conducted on 316L stainless steel powder. The results showed that porous metal material that meets the requirements of porous bionic human bone material (porosity of 33.4%-37.8%, average pore radius of 94.2-178 μm, elastic modulus of 7.43-12.76 GPa, nearly spherical regular pore) can be produced when sintered at 90-100 W laser power, with a scan speed of 21-23 mm/s and scan distance of 0.165 mm.
