Additive manufacturing is the key issue for production engineering in future. Conventional manufacturing technologies are being supplemented to an ever increasing extent by three-dimensional printing, which is already in successful operation in many sophisticated fields like the medical engineering, automotive and aerospace industries. The foundry, steel and aluminium industries have also recognised the potential of 3D printing. For this reason, the four Düsseldorf trade fairs GIFA, METEC, THERMPROCESS, NEWCAST 2019 (25. to 29. June 2019) are devoting a special show of its own to the subject of “additive manufacturing”.
