Abstract
An additive manufacturing apparatus includes a base, a layer forming portion configured to form a powder layer having a predetermined thickness by moving in a space above the base, an irradiation portion configured to irradiate the powder layer with an energy beam, a detection portion configured to detect a projecting portion formed on a solidified portion and a position of the projecting portion, and a control unit. The solidified portion is formed by irradiating the powder layer with the energy beam from the irradiation portion. A height of the projecting portion is larger than the predetermined thickness. The layer forming portion includes a high-rigidity thickness-determining portion and a low-rigidity thickness-determining portion. The control unit is configured to control operation of the high-rigidity thickness-determining portion and the low-rigidity thickness-determining portion, depending on a detection result by the detection portion.
