Russia has developed a technology for 3D-printing magnets with rare-earth elements

Researchers from the Ural Federal University and the Institute of Metal Physics of the Ural Branch of the Russian Academy of Sciences have developed a technology to produce magnetic materials with rare-earth elements using 3D printing.

"At this stage, scientists are investigating magnetic effects at the nanometer level. In turn, 3D printing makes it possible to achieve manufacturing accuracy of several microns. Controlling magnetic fields at such scales makes it possible to achieve completely new energy performance of electromagnetic devices. At the same time, efficiency losses are reduced due to the reduction of eddy currents during operation", - told Izvestia the first deputy director of the private institution "Science and Innovation" Alexei Dub.

Using the proposed method, experts produce magnets based on neodymium and iron, and by adding rare-earth elements they achieve improved properties. For example, the inclusion of praseodymium, terbium and dysprosium produces a material that can withstand 200 degrees Celsius, and additions of samarium and cobalt allow the products to function at 550 degrees Celsius.

The project was implemented under the leadership of the private institution Science and Innovations (part of Rosatom) as part of the unified industry thematic plan of the state corporation.
