PURPOSE:To precisely form a three-dimensional object not permitting a large quantity of non-cured resin to remain in the container in a way of forming a three-dimensional object by irradiating a beam of position-controlled light to liquid optical setting resin, and thus curing a desired part of the resin. CONSTITUTION:Into the surface of a supported liquid 3 that is contained in a glass vessel 1, not reacted with optical setting resin 4, and has a specific gravity larger than that of the optical setting resin 4, the optical setting resin 4 is poured from the injection inlet 2 of the optical setting resin in order to form a resin layer. Onto the resin layer, a light of laser 7 position-controlled by a deflector 6 is irradiated for curing the resin layer and forming a two-dimensional object. Next, the two dimensional object is lowered into the supported liquid 3 by means of a lowering jig 8. The surface of the supported liquid 3 is supplemented with a shortage of the optical setting resin 4, and a three- dimensional object 10 can be built up by repeating an operation of curing the resin layer and lowering the two-dimensional object. |
