Abstract: A three-dimensional object printing method includes first operation of concurrently performing ejection of liquid toward a workpiece by a head, emission of energy toward the workpiece by an energy emitter, and movement of the head and the energy emitter with respect to the workpiece by a moving mechanism, and second operation of concurrently performing emission of energy toward the workpiece by the energy emitter and movement of the head and the energy emitter with respect to the workpiece by the moving mechanism, without performing ejection of liquid by the head. A first irradiation distance, which is a distance between the workpiece and an emission face during execution of the first operation, and a second irradiation distance, which is a distance between the workpiece and the emission face during execution of the second operation, are different from each other.

Abstract: A three-dimensional object printing apparatus includes a head unit and a robot. The head unit includes a head and an energy emission unit. The head has an ejecting surface on which a nozzle is provided. The head is configured to eject ink from the nozzle toward a three-dimensional workpiece. The energy emission unit has an emitting surface from which energy for curing the ink is emitted. The robot changes relative position and relative orientation of the workpiece and the head unit. When a direction in which the head ejects the ink is defined as an ejecting direction, the ejecting surface is located closer to an ejecting direction side, which is a side toward which the ejecting direction goes, than the emitting surface is.
