Mechanical Performance Study for Rapid Prototyping of Selective Laser Sintering
Selective laser sintering (SLS) is an additive manufacturing technique used for the low volume production of prototype models and functional components.The lower strength of prototype parts might leads to bad finished quality. In this study, author used the coated sand casting as the material of selective laser sintering experiment, studied the processing temperature and time on the mechanical properties of post-processing, and the influence on gas-forming property and collapsibility of the pieces. And combined with casting experimental we can analyze the accuracy influence factors of precoated sand sintering parts and other performance assessment. Through analysis, it indicates that the post-processing of temperature influences on tensile strength of coated sand specimens under three different insulation temperature conditions.
