Super magnets from a 3-D printer

Magnetic materials are an important component of mechatronic devices such as wind power stations, electric motors, sensors and magnetic switch systems. Magnets are usually produced using rare earths and conventional manufacturing methods. A team of researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has worked together with researchers from the Graz University of Technology, the University of Vienna and the research institution Joanneum Research to produce specially designed magnets using a 3-D printer. The results were published in the journal Materials.
