PROBLEM TO BE SOLVED: To provide means for determining a support structure of a three-dimensional molded object.SOLUTION: A three-dimensional object molding apparatus includes: a head unit 3 capable of discharging a liquid; a curing unit 61 for curing the liquid discharged from the head unit 3 to form a dot; and a molding control part 6 for controlling an action of the head unit 3 to form dots in voxels determined as target voxels to form dots by a determining part in a set of voxels expressing a shape of a three-dimensional object to be molded, and thereby to mold the three-dimensional object as an assembly of dots. A determining part 95 determines target voxels where dots are to be formed, so as to form one or more support columns extending in a predetermined direction in accordance with a shape index value based on a probability of dots to be formed in the voxels. In the one or more support columns, the number of support columns having a cross section having a length in a first direction larger than a length in a second direction intersecting the first direction is greater than the number of support columns having a cross section having a length in the second direction larger than a length in the first direction.SELECTED DRAWING: Figure 1
