Abstract
A three-dimensional shaping apparatus includes: a supplying unit configured to supply powder to a storage unit to form a layer of the powder; a discharging unit configured to discharge shaping liquid to solidify the powder onto the powder; and a controlling unit configured to generate a control signal for controlling the supplying unit and the discharging unit based on shaping data indicating a shape of a three-dimensional shaped object. The controlling unit is configured to generate the control signal for laminating at least one sacrificial layer separable from at least one shaping layer corresponding to the three-dimensional shaped object in such a position that the at least one sacrificial layer is under the at least one shaping layer, based on the shaping data and powder information stored in advance and indicating change in thickness of a layer of the powder caused by permeation of the shaping liquid.
