Researchers from Sportstech Additive Manufacturing Group at Mid Sweden University have verified the patented technology of the Swedish company Exmet AB by succeeding in making the world first sample of iron based bulk metallic glass (BMG, also amorphous metal or glassy alloy) using electron beam manufacturing technology. This may be a breakthrough in the manufacturing of BMG components.
Worldwide research of BMGs is driven by the promises of their unique properties. Many application areas, from engineering to biomedical implant manufacturing, can potentially be revolutionized by using advantages of BMGs.
Until now, the manufacturing of even small BMG components has been quite complex and very expensive. Making large BMG components using traditional manufacturing methods, like melt spinning, casting, powder metallurgy or thermoplastic forming, is not possible.
