Additive technologies provide engineers with an innovative approach for design and manufacture of parts. The development of additive manufacturing technologies, such as selective laser melting, allows making metal products by melting the powder and obtaining a continuous solid-phase structure. The paper presents the results of study of selective laser melting process of steel 316L powder. Morphology and particle size distribution of the initial powder was shown. The chemical composition, microstructure and phase composition of the compact samples obtained by selective laser melting technology before and after heat treatment was investigated. The results show that the density of the samples was close to 100 %. Analysis of the microstructure of the samples before heat treatment shows a high crystallization speed, leading to the formation of the fine structure. Mechanical tensile properties for the samples before and after heat treatment were measured.Keywords: Selective laser melting, stainless steel, 316L, powder metallurgy, additive manufacturing
