MHI Machine Tool produces commercial metal 3D Printer using laser beams

Mitsubishi Heavy Industries Machine Tool Co., Ltd. has commercialised a metal 3D printer applying laser-based metal additive manufacturing technology. The first unit was delivered in March to the Industrial Research Centre of Shiga Prefecture, in Ritto, Japan. The commercial model is capable of laminating diverse metal materials at high speed, through use of a proprietary Directed Energy Deposition (DED) method in which metal powder material is continuously fed by nozzles to the laser fusing point. MHI Machine Tool and the Industrial Research Centre will collaborate in developing technological innovations relating to metal additive manufacturing. The metal 3D printer was developed under a research project of the New Energy and Industrial Technology Development Organization (NEDO), with participation of the Technology Research Association for Future Additive Manufacturing (TRAFAM). TRAFAM has sought to create a next-generation metal DED and additive manufacturing system employing MHI Machine Tool’s accumulated laser and positioning control technologies. […]
