In a modeling apparatus, a stage includes a modeling surface on which a modeled object is formed. A regulation member includes a surface including an adjacent region, the regulation member is arranged with respect to the stage to form a holding region for holding a material between the adjacent region and the stage. An irradiation unit selectively radiates an energy ray to a region of the material via the adjacent region. A first moving mechanism moves the stage and the regulation member relative to each other in a direction along the modeling surface. A second moving mechanism moves the stage and the regulation member relative to each other in a lamination direction of the material. A control mechanism variably controls, based on the number of laminated layers of the material, an irradiation position of the energy ray to the material in the direction along the modeling surface.

Modeling apparatus and manufacturing method for a modeled object

[Solving Means] An information processing apparatus to be used for a modeling apparatus including a stage, a regulation member, an irradiation unit, and a moving mechanism and includes an acquisition unit, an irradiation position control unit, and a compensation unit. The acquisition unit is configured to acquire the plurality of slice image data items. The irradiation position control unit is configured to variably control, in accordance with the number of laminated layers of a material, an irradiation position of the energy ray to the material in a direction of relative movement of the stage and the regulation member within a modeling surface of the stage. The compensation unit is configured to compensate for a reference position of at least one slice image data item of the plurality of slice image data items in accordance with a change of the irradiation position.
