A lightweight material that can be 3D printed and is stable enough to carry heavy loads: this is highly interesting for the automotive and aircraft industries because it could save up to 50% CO2 in the mobility sector. The aluminium alloy Scalmalloy® appears to have precisely such properties. In order to understand the reason for the high load-bearing capacity and to further optimise alloys in the future, researchers have carried out measurements in collaboration with Mercedes Benz, Premium AEROTEC, and Airbus.
