Claim 1:
2. The three-dimensional object printing apparatus according to claim 1, wherein
the first linear motion mechanism changes the relative positions of the first head and the energy emitter in relation to the workpiece in a third direction opposite to the first direction during execution of a second scan,
the second scan is executed after the first scan,
the energy emitter emits the energy toward the workpiece during the execution of the second scan, and
the first up-and-down mechanism and the second up-and-down mechanism change the positions of the first nozzle face and the emission face, respectively, such that the distance between the emission face and the workpiece in the second direction along the third axis is shorter than the distance between the first nozzle face and the workpiece in the second direction during the execution of the second scan.
