Parametric Optimization of Ss316l on Selective Laser Melting for Enhanced Biocompatibility

Abstract

The Selective Laser Melting technique is widely employed in the production of complexly shaped end products for a range of industries, including biomedical, aerospace, automotive, and defence. SLM is a complicated manufacturing process since a lot of factors influence the characteristics of the items that are printed using it. The SLM printing of fully dense parts is becoming more and more popular for various high-end applications. Because of their biocompatibility following implantation, titanium alloy and stainless steel alloy are the materials most frequently used in the fabrication of implants. The primary objective of this study is the parametric optimization of the SS316L alloy manufacturing process on the DMP Flex 350, utilizing SLM as a 3D printing technique. Response surface methodology (RSM), an optimization technique, and a genetic algorithm were employed to determine the optimal laser power, scan speed, and hatching distance in order to produce samples with the highest potential porosity and compressive strength.
