Abstract
Selective laser sintering (SLS) permits the fast, flexible, cost-efficient, and easy production of prototypes of required shape and size by using powder-based material. The physical prototype for design verification and working analysis is done directly on CAD tools. In SLS process optimization of influenced parameters will contribute to save time and material. In this study, optimal SLS process parameters by changing the layer thickness, bed temperature, and part orientation for hardness and ultimate tensile strength for the intended specimen by using Polyamide and also evaluate the mechanical behavior by using Vickers hardness tester and Ultimate tensile machine. The tests were conducted conferring to the Taguchi design of L9 orthogonal array at various combinations of process parameters and statistical optimization technique. Analysis Of Variance (ANOVA) was used to determine the optimal levels and percentage of influence of each parameter. The results postulate that the bed temperature is the main key factor followed by the part orientation and layer thickness for optimal value of the hardness and ultimate tensile strength of the SLS processed. This optimized value serves as a data base for the industries.
