Abstract

To examine the influence of the building directions on surface micro-structure and tribological characteristics of stainless steel 316L samples generated using selective laser melting (SLM) technology, parts were produced in three distinct building orientations (0°, 45°, 90°). The impact of construction orientation on stainless steel microstructure, mechanical characteristics, and machinability was examined. Scanning electron microscopy (SEM) was used to examine the microstructure of SLM samples. In the X-ray diffraction (XRD) patterns of the SLM samples, only, the FCC austenite phase was found. The γ-Ni phase's lattice constant in the SLM 45°sample was the lowest of these SLM samples. The surface roughness of the SLM 45° specimen was the highest compared to the other sections, while the surface roughness of the SLM 0° sample was the lowest. Large dendritic grains were uniformly distributed in the SLM 0° sample, but the roughest dendritic grains were produced in the SLM 45° sample. In addition, the SLM 0° specimen had the best tribological results.
