Additive manufacturing (AM) technology has been dramatically attracting attention
as a breakthrough technology in advanced manufacturing since 2013, and the sale of AM
systems has increased rapidly in the aerospace, automotive, and medical industries. The recenttrend of the development of metal 3D printers, the mechanical properties of the AMed materials
and the recent applications are introduced. Also the current state of the research developmentin the national (TRAFAM) project and the activities in the Advanced Additive Manufacturing
Center are introduced.
