At the Automate 2019 fair in Chicago, metal powder specialist Heraeus presented a world record additive manufactured gear wheel made of amorphous metals (also known as metallic glass or glassy metal). The gear wheel was 3D printed in a standard SLM system with material from Heraeus. With this world premiere, Heraeus is breaking through the boundaries of 3D printing and opening completely new design possibilities for a wide range of industries – from automation solutions and robotics to aviation, medical technology and the automotive industry. An amorphous metal is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline and have a glass-like structure. But unlike common glasses, such as window glass, which are typically electrical insulators, amorphous metals have good electrical conductivity. New design possibilities […]
