THREE-DIMENSIONAL ADDITIVE MANUFACTURING DEVICE, THREE-DIMENSIONAL ADDITIVE MANUFACTURING METHOD, AND THREE-DIMENSIONAL ADDITIVE MANUFACTURED PRODUCT

A three-dimensional additive manufacturing device emits a beam to a powder bed formed by laying a powder on a base plate to harden the powder bed selectively. A sensor detects 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 def...

Beschreibung
Zusammenfassung:	A three-dimensional additive manufacturing device emits a beam to a powder bed formed by laying a powder on a base plate to harden the powder bed selectively. A sensor detects 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 on the basis of the detection result, before completion of forming of the next layer.
