The operation unit includes a first part and a second part that cover a part of a supply region supplied with a powdery material and facing a first direction are aligned in a second direction, and includes a first opening extending between the first part and the second part in the first direction. The first face of the first part faces the second part, and is provided with a second opening. The mover moves the operation unit. The supply unit supplies an inert gas from the second opening to the first opening. The irradiator is spaced apart from the operation unit, and can emit an energy ray to the supply region through the first opening, and change a position with which the energy ray is irradiated.
