3D printing is usually considered as a layer by layer printing of plastics. Nowadays, this is only one of the varied applications in the field of 3D printing. Today it is possible to print with many different materials, such as metal. Metal printing can be done either with a laser (SLM), electron beam (EBM), wire and arc (WAAM), fused deposition modelling (FDM), binder jetting (BJ) or with nano particle jetting (NPJ). In case of electron beam melting, vacuum is required. Electron Beam Melting is an additive manufacturing method with which it is possible to print material out of titanium, cobalt, chrome alloy, steel, aluminum and copper. This is mandatory for special parts in the aerospace industry or medical market. Examples for printed parts are turbine plates or hip prosthesis. Read more
