Paper Title
Optimization of Selective Laser Sintering Process Parameters

Rapid prototyping is a group of techniques used for fabrication of physical part using three dimensional computer aided design (CAD) data. Selective laser sintering (SLS) is an additive manufacturing method which uses powder material to produce any physical product. In this paper author has consider three input parameters layer thickness, orientation, and porosity (artificial porosity as honeycomb structure) for making work pieces using SLS process before manufacturing the work pieces were design using factorial method. The material which has been used is CL 20ES (stainless steel-316). After producing work pieces, the testing of work pieces was done by considering output parameters like, ultimate tensile strength (UTS), hardness, yield strength, elongation, and weight. An analysis was done to obtain optimum parameter values for better output.
