摘要： A three-dimensional printing device includes a printing tank to accommodate a powder material and including an opening in at least a portion thereof, and an ejector facing the opening of the printing tank to eject a curing liquid to cure the powder material toward the opening. The ejector includes nozzle strings each including nozzles side by side in a first direction. The nozzles each eject the curing liquid and are located in each of the nozzle strings at a density of about 1200 dpi or lower in the first direction. The nozzle strings are spaced away from each other by a distance of about 5 mm or longer in a second direction perpendicular to the first direction.
