Some workpieces can’t be successfully manufactured using conventional methods such as casting. In such cases, the obvious choice is to use an additive manufacturing process. Optimising this process is the goal of the EWA project, which stands for the "development of carbon-martensitic tool steels for the additive manufacturing of highly stressed forming tools using wire-arc additive manufacturing". The starting materials for this additive manufacturing process are thin, powder-filled wires. They are additively processed into punching and forming tools. ...
