Abstract
A three-dimensional additive manufacturing device is configured to emit a beam to a powder bed formed by laying a powder on a base plate to harden the powder bed selectively. A sensor is configured to detect the shape or the temperature of a surface of the powder bed or a modeling surface. A defect in laying of the powder or a defect in emission of the beam is corrected based on the detection result, before completion of forming of the next layer.
