Experimental Investigation of SLM Parameters Effects on Roughness of 316L Parts

This work is an experimental parametric study that employs the design of experiments methodology to investigate the influence of printing parameters on the surface quality of 316L stainless steel parts manufactured through the SLM process. To achieve this objective, a full factorial plan consisting of three factors at three levels is used. The factors investigated are laser power (P), scanning speed (V) and hatching distance (HD). This study involves assessing the impact of these parameters on the roughness of SLM printed parts and determining the various combinations that result in a good surface condition.
