At the present time selective laser melting is among the most popular metal additive manufacturing processes. For this research work, selective laser melting was used to fabricate 18 blocks made of 316L stainless steel. Each block was fabricated under different processing parameters. The effect of processing parameters such as scanning speed, energy density, hatch spacing, laser spot size, etc. on microstructure and mechanical properties of these samples were studied. Scanning electron microscopy analysis was done on vertical and horizontal cross sections of each block to study the shape and size of melt pools under different building parameters. Additionally, microhardness and the microstructure of the samples were studied for vertical and horizontal cross sections individually for each of the samples. Moreover, ultimate tensile strength, yield strength, elongation and relative density of each sample was measured in order to investigate the role of each processing parameter on each of the mechanical properties.
