An additive manufacturing device is provided with a beam irradiation unit irradiating a conductive powder disposed in a layered shape with a beam, a nondestructive inspection unit detecting a flaw in a surface layer of an additively manufactured article formed of the hardened conductive powder, and an energy control unit controlling energy of the beam. The energy control unit increases energy of a beam when a repairing region set in accordance with results of flaw detection by the nondestructive inspection unit is irradiated with the beam.
