Purpose: The investigations have been carried out on test pieces of 316L stainless steel parts fabricated by Selective Laser Sintering technique. The effect of selective laser sintering parameters such as power output, laser distance between the points sintered metal powder during additive manufacturing as well as the orientation of models relative to the laser beam and substrate on the roughness, surface morphology and wear resistance of manufactured models were performed. Design/methodology/approach: To fabricate 316L stainless steel parts, the method using selective laser sintering (SLS) technique, using Renishaw AM 125 machine is utilised. Wear resistance, roughness and surface morphology of SLS produced samples prepared via different process parameters are investigated. Findings: The results show that the wear resistance and surface morphology are strongly influenced by orientation of the parts relative to the laser beam, power output of laser and laser distance between the points sintered metal powder during additive manufacturing. Research limitations/implications: In the nearest future, studies will be conducted to establish influence of laser parameters such as scan speed, focus offset, exposure time, diameter of laser beam and hatch parameters such as hatch type and hatch distance on the quality and density of AM steel parts. Practical implications: Stainless steel is one of the most popular materials used for selective laser sintering (SLS) processing to produce nearly fully dense components from 3D CAD models. Reduction of surface roughness is one of the key research issues within the additive manufacturing technique SLS, since one of the major cost factors is the post processing of surfaces by means of milling, turning, grinding and polishing. Originality/value: This paper can serve as an aid in understanding the importance of technological parameters on quality and wear resistance of manufactured AM parts made by SLS technique.
