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

In this paper, recent trend and applications on additive manufacturing with metal 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. 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 to fabricate the metal parts are explained. And also, the specification of the 3D printer for metal parts and the mechanical properties of various alloys are described. Finally, the importance of the additive manufacturing is described in the future manufacturing
