Electropolishing is an electrochemical surface treatment process that improves the appearance, smoothness and corrosion resistance of metal surfaces by selectively removing the material from the surface. This study focuses on the analysis of the electropolishing process of selective laser-melted (SLM) 316L stainless steel, which is widely used in marine, biomedical and chemical industries because of its superior corrosion resistance in harsh environments. This research investigates the effects of key process parameters (voltage, time and temperature) on surface roughness and polished depth. A full factorial experimental design was used to analyze the effects of these parameters, which were analyzed using Analysis of Variance (ANOVA) and multiple regression analysis. The findings revealed that voltage was the most effective factor, significantly affecting surface roughness by 67% and polished depth by 37.33%, both statistically significant (p < 0.05). Temperature also plays an important role in polished depth, contributing 33.52%, whereas its effect on surface roughness is minimal and not significant. The time parameter had a negligible effect on surface roughness (0.14%) and a moderate effect on polished depth (6.75%); none of the effects were statistically significant. In addition, multiple regression analyses produced equations with high r-squared values. The results highlight the importance of optimizing these parameters to improve the surface quality and functional performance of 316L stainless steel components, especially in applications where surface quality is critical.
