Beschreibung
Zusammenfassung:	An additive manufacturing device that forms a shaped object on a base by using one material of a powdery material and a linear material includes an additive material supply unit, a light irradiation unit, and a control unit that controls supply of the one material, irradiation with a light beam, and relative movement of the light beam. The light irradiation unit includes a central light beam irradiation part and an outer-side light beam irradiation part. The control unit separately controls an output condition of the central light beam irradiation part and an output condition of the outer-side light beam irradiation part, and the control unit increases a peak in a distribution shape of power density of the central light beam to be larger than a peak in a distribution shape of power density of the outer-side light beam to form the shaped object.
