Solid object shaping apparatus, control method for solid object shaping apparatus, and control program for solid object shaping apparatus

A solid object shaping apparatus comprising:

• a head unit that ejects a liquid containing a colorant component;
• a curing unit that cures the liquid ejected from the head unit so as to form a dot;
• and
• a control portion that controls the head unit so that a unit shaping body formed by a single dot or a plurality of dots is formed in a voxel, and a solid object is shaped by using the plurality of unit shaping bodies, when supplied with designation data which is data regarding a model indicating a shape and a color of the solid object to be shaped as a set of the voxels each having a predetermined rectangular parallelepiped shape and which designates the single dot or the plurality of dots to be formed in the voxel,
• wherein the plurality of unit shaping bodies constituting the solid object include
• a first unit shaping body having an amount of colorant components required to represent the color indicated by the model;
• and
• a second unit shaping body having an amount of the colorant components which is smaller than the amount required to represent the color indicated by the model, and
• wherein, in the second unit shaping body,
• two or more faces of six faces forming a surface of the second unit shaping body correspond to a surface of the solid object, and
• a proportion of an inner portion of the model of the second unit shaping body to the entire second unit shaping body is equal to or less than a first reference value.
