Abstract

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.

However, in the above method, there is a limitation on the shape of a modeled object that can be modeled, and it may be impossible to model a complicated shape, in particular, one having a concave portion inside. In other words, the shape of the recess that can be modeled by this method is limited to a simple shape such that the opening side becomes wider and becomes narrower as it goes inside, and modeling of a molded object having a recess with a complicated shape or a recess with a narrow opening side is equivalent to the recess. There is a problem in that it is not possible to remove the unnecessary portion that does not work.

Further, even in the case of modeling a modeled object having a shape capable of being modeled, there is a problem that removal of a portion corresponding to the concave portion is troublesome or difficult. Furthermore, when the cured portion 6 and the uncured portion 7 of the adhesive are formed by irradiation of the exposed portion 5 with respect to the outer portion other than the concave portion,
There is a problem that it is difficult to accurately draw the boundary line, necessary parts cannot be sufficiently adhered to each other, or unnecessary parts are adhered to the necessary parts, making it difficult to remove the unnecessary parts in the final step. .

Depending on the modeled object, the same sectional shape such as a rod shape or a cylindrical shape may be partially continuous,
In such a case, according to the method as described above, it is impossible to perform modeling while adjusting the thickness of one layer to an arbitrary thickness because the films having a constant thickness are laminated to perform modeling. For this reason,
There is a problem that the work is troublesome because layers having exactly the same shape must be formed many times. Further, since the films coated with the adhesive are stacked, there is a problem that unevenness is likely to occur due to uneven coating of the adhesive and the dimensional accuracy is deteriorated.

As described above, in the above embodiment, the auxiliary material layer 3 is used.
Since 2a is composed of the water-soluble auxiliary material 32 and the modeling material layer 38a is composed of the modeling material 38 insoluble in water, only the auxiliary material layer 32a is melted by washing the obtained laminated body 45 with water. Can be easily removed. As a result, it is possible to form a modeled object having a recess 44 of any shape as long as it has an opening. Further, the work of removing the unnecessary portion corresponding to the recess 44 becomes extremely easy.
