ADDITIVE MANUFACTURING DEVICE

WIPO Patent Application WO/2020/116609

A1

An additive manufacturing device that uses one material out of a powder material and a linear material and forms a molded article on a base. The additive manufacturing device comprises: an additive material supply unit; a light irradiation unit; and a control unit that controls the supply of the one material, the irradiation of a light beam, and the relative movement of the light beam. The light irradiation unit includes a central light beam irradiation unit and an outside light beam irradiation unit. The control unit independently controls the output conditions for the central light beam irradiation unit and the output conditions for the outside light beam irradiation unit. The control unit: increases the peak in a power density distribution shape for the central light beam to greater than the peak in the power density distribution shape for the outside light beam; and forms a molded article.
