Abstract: A three-dimensional deposition device includes a deposition head provided with a powder jetting port from which powder is jetted, a light beam irradiation port from which a light beam is emitted, and a fiber connection port connected to a fiber guiding the light beam; a head moving part that moves the deposition head along a vertical direction; a base part to which the powder is jetted and the light beam is emitted from the deposition head; a base moving part that moves the base part along a first direction orthogonal to the vertical direction and a second direction orthogonal to the vertical direction and the first direction; and a rotation mechanism that is connected to the deposition head and rotates the deposition head about a rotation axis crossing the vertical direction to switch, by rotating the deposition head, between a first state and a second state.

Abstract: A three-dimensional deposition device includes a deposition head provided with a powder jetting port and a light beam irradiation port to form a deposited body by the powder being melted and solidified; a shape measurement unit that measures a shape of the deposited body; a deposited body cooling unit that jets cooling gas to the deposited body to cool the deposited body; and a control unit. The control unit causes the shape measurement unit to measure the shape of the deposited body, determines whether to cool the deposited body based on a result of measuring the shape of the deposited body, and causes the deposited body cooling unit to jet the cooling gas to the deposited body to cool the deposited body in a case in which the cooling determination unit determines to cool the deposited body.
