Physicists in the Urals, commissioned by Rosatom, have developed a technology for 3D printing magnets from rare earth metals (REM). Physicists from the Ural Federal University (UrFU) and the Institute of Metal Physics of the Ural Branch of the Russian Academy of Sciences worked on the development.

Rare earth magnets are used in high-tech devices — electric generators, electric vehicles, space, aviation and energy sectors, and can last for decades or even centuries.
The technology will allow printing permanent magnets with improved properties of two types: based on iron and neodymium (neodymium magnets) with the addition of praseodymium, dysprosium and terbium (operate at temperatures up to plus 200 degrees) and samarium-cobalt (operate at temperatures up to plus 550 degrees).
Permanent magnets are products made of magnetically hard materials that can create a magnetic field around themselves for a long time without consuming energy. Rare earth permanent magnets are 5-6 times superior to the best non-rare earth magnets in terms of energy intensity.
Earlier www1.ru wrote that a new method for creating rare earth materials was developed in St. Petersburg.
