A Study on Topology of Lateral Surface of Components Manufactured by Selective Laser Sintering
This work presents the results of a study carried out to determine the topology of lateral surface and its effect on the process parameters of components manufactured by selective laser sintering (SLS). Using Taguchi’s experimental technique, an orthogonal array of L4 had been developed. Surface roughness was measured along built direction and analysis of variance (ANOVA) technique was used to investigate the effect of process parameters and to identify main process parameter that influences surface roughness on SLS components. It has been found that slice thickness and scan spacing have more significant influence than the laser power. Microstructure of the sintered specimen along the build direction was studied using Scanning Electron Microscope (SEM). It was observed that variations in slice thickness affect surface topology of SLS components.
