摘要

A control device 10 is provided that drives a horizontal driving device after ejection and curing of shaping material in one slice with a shaping material ejection device, controls a vertical driving device to move an ejection position to a slice after curing, and ejects and cures shaping material in a subsequent layer and thereby successively laminates slices. A hollow portion ES is provided in the slice corresponding to the boundary surface between different types of shaping material at which there is a change of the model material MA and the supporting material SA in the lamination direction of the shaped object from one to the other of the shaping materials. The control device 10 performs control to not eject shaping material or to reduce the ejection amount from the shaping material ejection device to a position corresponding to the hollow portion ES.
