Abstract

An additive manufacturing apparatus includes a powder-layer forming portion, an energy beam source, a shielding portion, and/or a removal portion. The powder-layer forming portion is configured to form a powder layer by moving between a waiting position and a forming area and supplying powder to the forming area. The energy beam source is configured to irradiate the powder layer with an energy beam. The shielding portion is disposed outside the forming area and between the forming area and the waiting position and configured to reduce powder reaching the powder-layer forming portion, the powder being scattered from the powder layer when the powder layer is irradiated with the energy beam by the energy beam source. The removal portion is configured to remove the powder scattered from the powder layer and having adhered to the powder-layer forming portion.
