Paper Title
Optimization of Selective Laser Sintering Process Parameters

Abstract
Rapid prototyping/Additive manufacturing is a process which promises to deliver superior mechanical properties as well as reduced costs for components of complex geometries and Selective laser sintering (SLS) in particular is a subclass highly suitable for manufacturing of metallic components. In this paper the impact of layer thickness, orientation, and porosity (artificial porosity as honeycomb structure) on the mechanical properties such as ultimate tensile strength (UTS), hardness, yield strength, elongation, and weight of parts manufactured from CL 20ES (stainless steel-316) using the SLS technique was studied. Analysis of the specimens thus manufactured yielded UTS of 739.11 MPa for zero porosity and orientation for a layer thickness of 30 mm.
