摘要： A three-dimensional shaping method that allows defects in three-dimensional shaped products to be avoided by rapidly detecting sintering defects, wherein the sintering step comprises the following operations:
a. measuring the reflection intensity of the laser beam or electron beam irradiated in each sintering step, or the reflection intensity of light other than the laser beam,
b. commanding to continue sintering within the next time unit, or the next powder layer forming step is given, when it has been detected that the reflection intensity of the process a is within a standard range for a given time unit, and then,
c. judging that a sintering defect has been produced, and commanding to cancel sintering in the next time unit, or the next powder layer forming step is given, when it has been detected that a condition has occurred in which the reflection intensity of the process a deviates from the standard range for a given time unit.
Further, the cause of the sintering defect is determined as the control system of the beam or the powder layer surface, based on the speed of change of a spectral image or reflection intensities.
