Abstract
A liquid discharge apparatus to form a three-dimensional object with a plurality of layers of ink laminated includes a stage; a discharge head to discharge photocurable ink, toward the stage, for each layer in a height direction of the three-dimensional object; a driver to move the discharge head or the stage relative to the other; an irradiation device to cure the ink, for each layer, with curing light irradiation; and circuitry. The circuitry causes the discharge head to discharge the ink, according to slice data indicating a printing region and a non-printing region in each layer generated by sliding in the height direction of the three-dimensional object, corresponding to movement of the discharge head; and change, in each layer, illuminance of the curing light in the printing region and the non-printing region in accordance with a state of the printing region and the non-printing region indicated by the slice data.
