20090004381 | THREE-DIMENSIONAL MOLDING APPARATUS AND THREE-DIMENSIONAL MOLDING METHOD - A three-dimensional molding apparatus for binding powder with a binding liquid to mold a three-dimensional object. When the three-dimensional object is cut into cross-sectional layers, a cross-section data generating unit generates cross-section data for each of the layers.
