  • Patent number: 9827715
    Abstract: A three-dimensional formation apparatus includes a head unit which can discharge liquid in a first direction and a control unit which controls the head unit. The control unit forms a cross section object by discharging the liquid containing a second quantity which is smaller than the first quantity to a changed portion where an outline of the cross section object is simultaneously changed in the second direction and the third direction, in the first cross section object formation process, and executes a filling process of discharging the liquid containing a third quantity which exceeds the first quantity when the third quantity is added to the second quantity to a portion to which the liquid containing the second quantity is discharged, after the first cross section object formation process is executed and before the second cross section object formation process is executed.
