1. A three-dimensional formation apparatus which forms a three-dimensional object, the apparatus comprising:
a head unit which discharges liquid which is one material of the object in a first direction, among the first direction, a second direction, and a third direction orthogonal to each other; and a control unit which forms the object by laminating the plurality of cross section objects by executing a cross section object formation process of forming a cross section object for one layer of the object several times by discharging the liquid containing a quantity equal to or smaller than a first quantity to a designated coordinate among coordinates representing a position in the second direction and a position in the third direction, by controlling the head unit, wherein the control unit
forms a hollow on a changed portion where an outline of the cross section object is simultaneously changed in the second direction and the third direction towards the inside from the outline of the cross section object in the second direction or the third direction, in the first cross section object formation process among the cross section object formation processes executed several times, andexecutes a filling process of discharging the liquid containing a second quantity which is larger than the first quantity to the hollow so as to come in contact with the cross section object formed in the first cross section object formation process, to fill at least a part of the hollow with the liquid, after the first cross section object formation process is executed and before the second cross section object formation process is executed. |
