Abstract
A layer forming apparatus includes a loading unit including a stage onto which powder is supplied, a rotator that flattens the powder on the stage to form a powder layer, and circuitry. The circuitry causes the rotator to move in a first direction parallel to a surface of the stage and rotate while contacting the powder on the stage to form the powder layer. Further, the circuitry causes the rotator to move in a second direction opposite to the first direction and rotate while contacting surplus powder not on the stage.
