Interview – Tobias Röhrich imagines a fully automated Metal AM chain.

Tobias Röhrich explains the existing range of materials, why a new design is not necessarily indispensable, and how he imagines a fully automated additive process chain.

GEFERTEC GmbH (Berlin) is making new inroads in Metal AM: with arc welding, 5-axis-machines weld wires layer by layer onto each other. The blanks produced in this way are near-net-shape, thus minimizing time and tool effort in milling postprocessing. In this interview, manager Tobias Röhrich explains the existing range of materials, why a new design is not necessarily indispensable, and how he imagines a fully automated additive process chain.

Tobias Röhrich: I co-founded GEFERTEC at the beginning of 2015 with my colleague Georg Fischer. We met as research assistants at the TU Berlin. It all began with the question why all manufacturers of additive manufacturing systems in the metal sector relied on powderbed technology. We both have a background in welding technology, and we knew about the advantages of wire. First attempts showed that a layered construction of components consisting of wire works well. As lasers do not give much advantage here, we switched to the cost-efficient, uncomplicated arc-welding. We then began with founding our company, and we found a strong partner in the Scansonic Group. Last autumn, we presented our system at the EMO, and it is already in use with our first customers.
