Abstract
An additive manufacturing apparatus includes a powder layer forming portion, an energy beam source, and a contact detection sensor including a plate-like probe. The powder layer forming portion is configured to form a powder layer in a predetermined region. The energy beam source is configured to radiate an energy beam to the powder layer formed by the powder layer forming portion to fuse or sinter the powder layer so that a solidified layer is formed. Presence or absence of a projection portion on a surface of the solidified layer is detected by using the contact detection sensor.
