In the work, a literary review of materials was conducted, devoted to different areas of studying selective laser melting (SLM) and selective laser sintering (SLS) technologies in order to analyze the processes associated with selective laser surfacing occurring during SLM and SLS, as well as the impact of technological measures on the final structure, mechanical and service characteristics of a manufactured part in the additive manufacturing of structural elements on a thin-walled base. The main tasks of research works analyzed in the review were studies focused on the features of structural elements formation on a thin-walled by means of SLM and SLS technologies: modelling of additive manufacturing processes; aspects of planning experiments and manufacturing processes; studying the course of SLM and SLS processes in the given conditions; need in pre- or post-treatment of material; as well as analysis of the end microstructure and characteristics of specimens manufactured using these technologies. Based on the results of literary analysis, problems were identified and the prospects of using SLM and SLS processes were considered during the formation of structural elements on a thin-walled base. A number of aspects were justified, on which it is necessary to pay attention during studies of SLM and SLS processes when working with a thin-walled base. 36 Ref., 9Fig.
