Analysis of Ti6Al4V Alloy Prototype Fabricated via Selective Laser Melting

Abstract

During laser-based additive manufacturing, powder is selectively fused layer by layer to achieve the desired shape. Powder also serves as an integrated support framework, allowing for a wide range of material alternatives. Selecting suitable material whether it should be pure material powder or composite material powder such as titanium-based alloy which have wider application in biomedical industries to make surgical implants and orthodontic appliances, which requires good fatigue strength. The purpose of this analysis is to obtain a better understanding of the laser-based additive manufacturing process with the help of finite element simulations. The effect of variation in laser power, scan speed and layer thickness are considered the essential parameters for thermal and mechanical analysis of a part. One by one varying the process parameters such as laser power, layer thickness, beam radius, and scan velocity to generate the stress distribution, total distortion, and solid fraction of the part. Comparing the results and evaluating the most appropriate result from this. Keeping records of these results and validating these results with the results of fabricated part.
