The structure of hard magnetic and soft magnetic alloys manufactured on a RussianSLM FACTORY init by selective laser melting (SLM) from a spherical powder less than 80 μm in size has been studied. The powder is made by melt atomization from ingots. At various scanning speeds and laser power, additive samples were manufactured to study the structure, magnetic parameters, and also fractal analysis. According to the research results, recommendations were given on changing the melting modes and conducting thermal post-processing of materials. By constructing a hysteresis loop, data were obtained indicating the achievement of magnetic characteristics in additive samples that are close in magnitude to magnets of traditional founding technology. Prototypes of complex-shaped additive magnets have been made.
