Miniature permanent magnets printed by Russian scientists Research & Education
Scientists from the Ural Federal University (UrFU) and the Ural Branch of the Russian Academy of Sciences are determining the optimal conditions for 3D printing permanent magnets from hard magnetic compounds based on rare-earth metals. This will make it possible to start small-scale production of magnets, in any shape, and create complex magnet configurations. Such magnets are suitable for miniature electric motors and electric generators, on which pacemakers work. In addition to this, as is typical of AM, the technology minimizes production waste and has a shorter production cycle. A description of the method and experimental results are presented in the Journal of Magnetism and Magnetic Materials.
