A Review on Selective Laser Sintering Process on CL50WS Material

This paper describes a variety of fundamental research of Selective Laser Sintering Process on CL50WS (Hot Work Steel) Material which the authors have recently performed. Rapid Prototyping (RP) can be defined as a group of techniques which is used to quickly fabricate a scale model of a part or assembly using three-dimensional computer aided design (CAD) data. The Selective Laser Sintering (SLS) is a one of the rapid prototyping (RP) technology by which physical objects are created directly from CAD model using layer by layer deposition of extruded from material. The quality of SLS produced parts is significantly affected by various parameters used in the process. SLS produces higher strength and surface finish metal parts. In this present work two important process parameters of the SLS process such as layer thickness, Orientation. Influence of each parameter on responses such as change in Tensile Strength and Surface roughness of the build part are essentially studied. The effect of process parameters on responses are studied by Taguchi Method. Then optimization of process parameters is made by ANOVA analysis.
