In this work in order to determine the relevant directions of research of different scientific components of the process of selective laser melting (SLM), as well as technological measures affecting the final structure, mechanical and service characteristics of a manufactured part, a literary review of the materials was made devoted to different directions of research of SLM technology. The directions of scientific works considered in this review were: research and deepening knowledge on the influence of the energy component of SLM process; possibilities of SLM process modification by the control of laser focus value; study of modes and methods of SLM processing as well as final microstructure of samples; study of corrosion resistance of products, manufactured using SLM. Based on the results of the literary analysis, the problems and prospects of studying SLM processes for materials of aerospace industry are shown, the need in creating a systematic comprehensive approach to the study of the components of SLM process, as well as deepening knowledge about the technological capabilities of its use. 46 Ref., 6 Fig.
Keywords: selective laser melting (SLM), additive manufacturing, powder metallurgy, control of focal spot size, scanning strategy, metals of aerospace industry.
