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.
