Recent Trend and Applications on Metal Additive Manufacturing Technology : A Review

Hideki KYOGOKU*1

In this paper, the recent trend and applications on metal additive manufacturing technologies are reviewed. Recently, additive manufacturing technologies are paid great attention especially in the aerospace, automotive, and medical industries because of the possibility to manufacture lighter structures to reduce weight, complex high-performance parts, and so on. Therefore, a national project was launched by the Japanese government in April 2014 to develop the innovative 3D printers with electron beam and laser beam systems as well as the technology of powder bed fusion and directed energy deposition processes. The approaches to the research of the national project and other researches with manufacturing companies in the Advanced Additive Manufacturing Center are described.

Keywords: Additive Manufacturing, 3D Printer, Laser Sintering/Melting, Electron Beam Melting, Laser Metal Deposition
