Additive Manufacturing
In Additive Manufacturing (AM) or 3D printing, components are produced by applying material layer by layer. For the data preparation of the parts, a CAD software is needed. The components are printed using metal, polymer, ceramic, composites or hydrogels/bio inks as building material.

Patented Parallel Geometry
Multi-optional 6-axis machining centre from METROM
The Mobile Smart Factory uses a hybrid machine from METROM for component production. Based on a patented parallel kinematics concept the machine combines Gefertec’s WAAM module with a milling and drilling unit.
The automated building with integrated finishing processes is based on CAD data of the component created in the operating container. With this solution, the system operator only has to set up and position the workpiece. The welding and machining process runs as an NC program based on pre-qualified parameters.
Operating principle
The main spindle of the machine is centrally positioned, allowing the machining of large workpieces.
The measuring of the workpiece, contour welding and milling are carried out consecutively in one clamping position. Subsequently an additional tool can be used to smoothen out the roughness of the surface. All technological steps are realised by a direct tool change in the working area of the machine. Further possibilities like for example laser welding with wire or powder, screw extrusion additive manufacturing or plasma welding can be integrated later on, too.
