From wind turbines and electric motors to sensors and magnetic switching systems, permanent magnets have many electrical applications. The production of these magnets usually involves sintering or injection molding. But due to the increasing miniaturization of electronics and the more exacting requirements, this places on magnetic components in terms of geometry, these conventional manufacturing methods are frequently coming up short. Additive manufacturing technologies, however, offer the required flexibility of shape, enabling production of magnets tailored to the demands of the application in question.
