Abstract
A three-dimensional modeling apparatus includes a stage, a head, an adjustment mechanism, an ejection command means, and a control means. On the stage, a powder material is accumulated. The head ejects ink to the powder material on the stage. The adjustment mechanism adjusts a relative height of the stage and the head for each predetermined layer thickness so that a three-dimensional object is formed on the stage by the predetermined layer thickness. The ejection command means causes the ink to be ejected from the head so that the powder material is colored a plurality of colors corresponding to multilevel luminance information items in a multivalued image obtained by performing a multivalued processing of luminance with respect to a two-dimensional cross-sectional image data of a modeling target object. The control means controls the adjustment mechanism and the ejection command means so that the multivalued image is drawn for each layer thickness.
