Fundamentals of Selective Laser Sintering of 316 Stainless Steel Powder
Selective laser sintering technology is used for manufacturing parts from 316 stainless steel powders. Experiments were carried out on a Nd:YAG laser machine (LMY400) with 400W. Powder is layered by a roller over the surface of a 100mm diameter build cylinder. Effects of processing parameter on the scan line width, the scan line height, the single layer structure and the multilayer structure are investigated. The results show laser power, scan speed and layer thickness have a great effect on the scan line width and line height. Furthermore, the stable and continuous vectors are formed with the increasing of the number of layers.
