Additive Manufacturing (AM) technology has been dramatically attracting attention as a breakthrough technology in advanced manufacturing. However, Japan lags behind Europe and the U.S.A. in addressing this technology. Therefore, the Ministry of Economy, Trade and Industry (METI) of Japanese Government established a new research association, “Technology Research Association for Future Additive Manufacturing (TRAFAM)”in 2014 in order to implement the national project on the development of innovative metal Additive Manufacturing systems that will meet the world's highest standards (FY2014-FY2018). Consequently, two PBF-EB type machines, two DED hybrid type machines and a PBF-LB machine were developed together with software and powder production technology. At next stage (FY2019-FY2023), TRAFAM develops a real-time monitoring and feedback control technology to assure the final product quality and process repeatability in the NEDO project. In this talk, TRAFAM activities are mainly introduced. In addition, current R&D and industrial perspectives of metal additive manufacturing in Japan are mentioned.
