The paper briefly overviews additive technologies, the results of tests and studies of the technological properties of powder materials, samples from materials obtained from powders using selective laser melting technology (SLM) based on the SLM 280 3D printer, their physical and mechanical properties. The study describes the prototypes of SLM-based elements of spacecraft antenna-feeder systems (AFS) manufactured in Lavochkin Association. Taking into account the capabilities of SLM technology, the design of the elements was changed: instead of assembly units, design documentation (DD) for one-piece products was developed. The paper introduces the results of tests of radio technical parameters of some typical AFS elements. Within the framework of studies, we assessed the following advantages of SLM technology: reduction of the cycle, labor intensity and cost of parts manufacture; reduction in weight, increase in the stability of the structure geometry and decrease in the number of defects in the process of products manufacture.
