3D PRINTING

– SCREW EXTRUSION ADDITIVE MANUFACTURING –

THE REAL 3D PRODUCTION

The Screw Extrusion Additive Manufacturing (SEAM) technology is a 3D print extrusion unit developed by Fraunhofer IWU for the production of large components. The combination of the nozzle and our parallel kinematics provides new production approaches for additive manufacturing.
