PURPOSE: To realize the shaping of a complicatedly shaped matter, and control the thickness of one layer with favorable dimensional accuracy by a structure wherein a laser irradiation part equipped with a condensing device movable toward a bed part, an auxiliary material feeding part, a shaping material feeding part and an ultraviolet emitting part are provided for curing the auxiliary material and shaping material. CONSTITUTION: By reciprocating a hopper 28, into which auxiliary material 32 is charged by opening the faucet 33 of an auxiliary material tank 31, liquid layer having the same thickness as the height of a small projection 30 on a bed part 21 is formed and then solidified with an ultraviolet light irradiating lamp 41 in order to form the auxiliary material layer. Next, a laser emitter 27 is put into actuation so as to sublimatingly remove the predetermined portion of the auxiliary material layer by shifting a condensing device 24 and a reflecting mirror 25 in X- and Y-additions. Next, a hopper 35, into which shaping material 38 is charged by opening the faucet 39 of a shaping material tank 37, is reciprocated. At this time, the shaping material 38 is discharged only into the recessed portion, from which the auxiliary material layer is removed. After that, the shaping material 38 is hardened with the ultraviolet irradiating lamp 41. By repeating the above process, a laminate is obtained. |
