Abstract

A form of additive manufacturing named selective laser melting (SLM) involves a laser to melt and fuse metallic powders together layer by layer to produce solid parts. In SLM, a number of variables, including laser power, scan speed, layer thickness, and hatch spacing, can influence the final product's quality and precision. The best values for these factors to produce the desired qualities in the finished product are commonly found through experimental investigations. In this investigation, we produced titanium alloy pieces from the Ti6Al4V ELI material using SLM technique. The effect of three factors, namely laser power, scan speed, and hatch distance, on the density, micro-hardness, and surface roughness of the produced components was systematically studied and optimised using the Taguchi technique, a statistical method for designing and evaluating tests. The signal-to-noise (S/N) ratios, which are a measure of the magnitude of the output signal relative to the level of noise, and ANOVA, a statistical technique used to assess the significance of variations between means, were then employed to examine the results. According to experimental findings, a sample with a density greater than 99.54%, a micro-hardness of 386 HV, and a roughness measurement of 10.86 µm were produced. The process variables that had the greatest impact on the mechanical characteristics of the laser-deposited Ti-6Al-4V alloy were found to be laser power and scanning speed.
