Popis: —The additive manufacturing of functional materials has a number of advantages over the sintering, which consist in the possibility of fabricating near-net-shape and locally forming the properties. In the present study, the effect of synthesis parameters on the phase composition and magnetic hysteretic properties of single-layer Nd2Fe14B-based permanent magnets synthesized by selective laser sintering is investigated. The causes for the effect of synthesis parameters on the magnetic hysteretic properties are considered. The possibility of reaching a coercivity of single-layer magnets of 19.5 kOe, which are free of heavy rare-earth metals, is demonstrated.
