Abstract
A device for fabricating a three-dimensional fabrication object includes a fabrication part, a flattening member to place powder in the fabrication part to form an excessively thick powder layer and remove the powder on the top surface side of the excessively thick powder layer multiple times to obtain a powder layer while moving in a direction orthogonal to a lamination direction of the powder layer, and a fabrication unit to bind the powder in the powder layer to form a laminar fabrication object, (wherein the laminar fabrication object is formed repeatedly to fabricate the three-dimensional fabrication object), wherein the amount of a layer thickness of the powder removed for the last time is less than that for any other time.
