Optimal Scanning Condition of Selective Laser Melting Processing with Stainless Steel 316L Powder

摘要：

This study aimed to investigate the stainless steel 316L processing by means of selective laser melting (SLM).The processing parameters under consideration included laser power (25-225 W), scanning speed (50320 mm/s), and scan spacing (0.04 and 0.06 mm).Every processing was constrained the layer thickness as of 100 μm.All parameters were performed based on two experiments, line scanning and multiple layers scanning.Each of final workpieces was examined by visual inspection, density measurement, hardness, and built rate.From the experiments, the optimal processing conditions which produced the smooth tracks were obtained.The workpiece processed by this optimal processing condition presented quality characteristics with 97.6％ density and 220±6 HV hardness.
