Abstract

3D Additive Manufacturing is the heaven-sent child for Internet of Things (IoT) in the digital age, and is a process that can be used for customized design and production. In particular, metal Additive Manufacturing enables not only the fabrication of complex shapes but also the control of crystal orientation at the atomic level by locally melting and solidifying the metal materials, thereby realizing high functionality of the product through simultaneous design of shape and materials properties. Therefore, it is expected to be applied in various social infrastructure fields including medical, energy-related,aerospace, and automotive, and also as a means of adding high value. In this review article, the new manufacturing concept that can be realized by metal Additive Manufacturing is introduced.
