Abstract

A three-dimensional deposition device and a three-dimensional deposition method used to highly accurately manufacture a three-dimensional object are provided. A three-dimensional deposition device for forming a three-dimensional shape by depositing a formed layer on a base unit includes: a powder supply unit which supplies a powder material; a light irradiation unit which irradiates the powder material with a light beam so that at least a part of the powder material irradiated with the light beam is sintered or melted and solidified to form the formed layer; a heating unit which selectively heats an area having passed through a position irradiated with the light beam in the base unit or the formed layer or an area not having passed through the position irradiated with the light beam; and a control device which controls operations of the powder supply unit, the light irradiation unit, and the heating unit.
