The purpose of the article is to choose a selective laser sintering method suitable for basic parts manufacturing, as well as to analyze mechanical characteristics of parts obtained using selective laser sintering, depending on the technology of their production. Basic parts manufacturing is a complex and expensive process which includes casting or welding, milling of base surfaces, and boring of holes. As a rule, body is the largest part of the structure, and accuracy of its base surfaces manufacturing directly affects performance of the entire mechanism. Method of producing blank parts is of paramount importance in body manufacturing. Parts of this type must ensure precision of the relative position of individual elements, both at rest and in the dynamic mode of machine operation. At the same time, it is known that all methods of blank parts production are characterized by the presence of residual stresses in the blank part. Gradually relaxing, these stresses “come out” in the form of deformations, which leads to displacement of parts and units of the entire mechanism, and a change in their interaction. This directly affects performance and resource of the entire machine.
