Electric pulses precisely shape 3-D-printed metal parts


Professor Dirk Bähre and his research team at Saarland University have developed a non-contact method of transforming metal parts fabricated by a 3-D printer into high-precision technical components for specialist applications. The novel method enables them to process parts made from strong, lightweight metals to produce precision-finished components with complex geometries and dimensional tolerances of a few thousandths of a millimeter. The team of manufacturing technologists combine metal 3-D printing and electrochemical machining (ECM).
