Paper Details

The Selective Laser Sintering (SLS) is a one of the rapid prototyping (RP) technology by which physical objectsare created directly from CAD model using layer by layer deposition of extruded material. SLS produces high er strengthand surface finish parts. In this present work important process parameters of the SLS process such as layer thickness andorientation of part is taken as input parameter. Specimens are prepared for Tensile testing as per ASTM standards. Theirinfluence on responses such as Tensile strength, Tensile Modulus, and Elongation of the test specimens will be studied. Theapplication of Analytical hierarchy process (AHP) method and multi objective optimization on the basis of ratio analysis(MOORA) method for selecting the optimal value of output parameters of Selective laser sintering machining process. Thecurrent study reveals that the results obtained using the AHP with MOORA methods are satisfactory and it prove theapplicability, and potentiality of these methods. After results, it is concluded that layer thickness is more significantparameter for SLS process than orientation. If we increase layer thickness and orientation mechanical property like tensilestrength and Tensile Modulus decreases.
