Zusammenfassung:	Provided are a manufacturing apparatus and method for a three-dimensional object, and a material supply unit to be used in the manufacturing apparatus for a three-dimensional object which make it possible to obtain an intended three-dimensional object formed by accumulating a shaping material and to hardly form an unnecessary portion on the surface of the three-dimensional object. A nozzle part (4) for ejecting a shaping material (81) is provided with a shut-off pin (5) for opening/closing a channel end part (41) from inside E1. When closing the channel end part (41), a stop position x(mm) of a tip (501) of the shut-off pin (5) with respect to the position of a tip (411) of the channel end part (41) satisfies a relation of -3D¦x¦6D wherein an equivalent diameter of the channel end part (41) of the nozzle part 4 is represented as D(mm) .
