 In this paper, recent trend and applications on additive manufacturing with metal arereviewed. Recently, additive manufacturing technologies are paid great attention especially inthe aerospace, automotive, and medical industries because of the possibility to manufacture
lighter structures to reduce weight, complex high-performance parts, and so on. The
classification of additive manufacturing technologies by the ASTM F42 committee is introduced,
especially the powder bed fusion and direct energy deposition methods which are applied tofabricate the metal parts are explained. And also, the specification of the 3D printer for metalparts and the mechanical properties of various alloys are described. Finally, the importance of
the additive manufacturing is described in the future manufacturing.
