Mitsubishi Heavy Industries Machine Tool Co., Ltd., a group company of Mitsubishi Heavy Industries, Ltd. (MHI) has announced the first commercialization of its metal 3D Printer.  The industrial system will be used in Ritto, by the Industrial Research Center of Shiga Prefecture.

The metal 3D printer was developed under a research project of the New Energy and Industrial Technology Development Organization (NEDO), in collaboration with the Technology Research Association for Future Additive Manufacturing (TRAFAM). 

 “Applying a proprietary DED method, laser beams emitted through dual nozzles pass through surrounding metal powder, causing fusion (immediate coagulation) at the focal point, and nozzle movement results in progressive additive manufacturing. Molding speed is more than 10 times faster than the powder-bed fusion method of extracting a formed object—whereby, after the metal powder has been spread and manufacturing has been completed by fusion and coagulated lamination, the superfluous unsolidified powder is removed—and metal powder waste can be suppressed. Because it is possible to perform additive manufacturing to a part’s surface by way of repair, to double-laminate different metal powders, and to manufacture large parts, significant expansion of applications is anticipated through innovations during the processing phase and combined use with other machine tools”, the company explained.

Over time, users will certainly question maintenance and management operations of materials. MHI Machine tool anticipates this need and is currently developing monitoring feedback capability that will monitor and stabilize the manufacturing status.
