Balling process in selective laser sintering of 316 stainless steel powder was investigated. It showed that the balling phenomenon was ascribed to the higher liquid viscosity and surface tension effect during laser sintering. The effects of laser power and scan speed on the balling initiation was studied. It was found that increasing laser power and scan speed within a moderate range can reduce balling effect. However, care should be taken to control laser powers and scan speeds that can be used since their excessive increase may give rise to detrimental effects.

Element Analysis

Finite element analysis software ANSYS is a platform, Using the Parametric Design Language of APDL language to write programs to simulate the temperature field of the laser sintering of 316L stainless steel powder. Building the model of Finite element analysis to analysis the simulation's various difficulties, such as the thermal parameters at different temperatures, the loading of the heat flux and some of the key parameters. Researching the affect of laser power and scanning speed on the temperature field, it’s valuable in researching the temperature field of the metal powder sintering

Scan Line

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.
