Researchers at Saarland University introduced 3D-printed motor components made from metallic glass alloys, featuring an amorphous (glass-like) atomic structure that reduces magnetic friction. The EU-funded AM2SoftMag project produced alloys containing 70–80% iron and used laser powder bed fusion to build parts with 50-micrometer layers.
The team screened hundreds of five-element compositions to find three alloys that resist crystallization and are compatible with additive manufacturing; industrial partner Heraeus AMLOY Technologies handled the printing of magnetic pieces. Partners in Spain, Italy, Poland and Germany collaborated on materials selection and process development to bring the prototypes toward scalable production.
For consumers and manufacturers, these amorphous components promise lower "iron loss" in electric motors, improving efficiency for drones, e-bikes and other devices by reducing heat and energy waste. The work points to a trend of pairing advanced alloys with AM to cut performance losses in next-generation electromechanical systems.
