Abstract
The disclosure provides a method of additive manufacturing a three-dimensional object, which can prevent a blade from being caught by a deformed part that is generated due to an unpredictable change of a sintering condition. In the method of additive manufacturing the three-dimensional object, if a deformed part having any height is generated on the upper surface of the nsintered layer, when the next n+1sintered layer is formed, the n+1powder layer is irradiated with laser by avoiding the region where the deformed part is generated. Then, after the n+2powder layer is formed, the unsintered part is sintered together with the n+2powder layer.
