Fabrication Parameters

In the modern manufacturing the 3D printing technology is the largest reform. The Selective Laser Sintering (SLS) occupies a special place in a hierarchical manufacturing technology. In the SLS process the shrinkage brought the ports size decreased and caused the warp. The fabrication parameters in SLS process played a major influence on the molding accuracy. With the sintering process of Polypropylene composite powder, the fabrication parameters were investigated. Through the gray relational analysis to manipulate the test date about the warp and molding accuracy, we could determine the impact of the most important factors molding accuracy. The result showed that about the warp and molding accuracy the most important parameter was the scan speed, followed by laser power.
