All conveyor lines and machines should work smoothly in order to ensure a well-timed production during production. There are parts and nods, the failure of which leads to the failure of the entire conveyor. It is the delivery time and financial losses due to equipment downtime that make the problem of quick reproduction of the relevant part to replace the original one. In this work, the process of creating a test piece using selective laser fusion (SLS) technology was considered. In this case, the economic efficiency of the fabrication of products depends directly on the effective and correct solution to the problems of technological preparation of additive production. The printed model was tested in direct contact with water for 500 hours. Fatigue tests were performed using 40% primary and 60% secondary powder ratios. To quantify the properties of the material for given geometry, a series of tensile testing of products was carried out. To identify the best ratio of strength, elasticity, and manufacturing cost for testing, samples were offered with different percentages of powder. It was noted that the cost of manufacturing spare parts, tools, and accessories (SPA) using 3D printing depends on many factors. The product geometry determines their volume, and the density of their arrangement in the chamber was recognized as a crucial impact factor. The accumulated experience and analysis of the criteria allowed us to offer several layout options that can lead to a maximum economic effect.
