Horizontal cross-sectional data of the dimensional model 44 is input in advance. The horizontal cross-sectional data is the shape of the three-dimensional model 44 taken along the horizontal direction so as to be cut into rounds at each required thickness in the height direction (Z direction). The three-dimensional model 44 in FIG. 4 is a model of a car, and the shape of a cross section 45 having a required thickness near the roof of the car body is one piece of horizontal cross-sectional data. The three-dimensional model 44 as a car model is formed as a stack of many thin cross-sections, and the shape of all the cross-sections is determined by the computer.
3 is input. Based on the horizontal section data input to the computer 43, the computer 43 controls the pump 37 and the robot device 39. In FIG. 4, the lowest part of the tire 4 is first formed on the forming plate 46, and then the center and upper parts of the tire 47 and the bottom part of the vehicle body 48 are formed thereon, and the upper parts are stacked one after another. .

。The resin flowing out from the nozzle 38 is irradiated with light from a light projection part at the tip of the nozzle 38. As a result, the resin that flows out immediately starts to harden and is stacked on the cross section 45 of the model 44 that has already been laminated and hardened to the required hardness.
［発明が解決しようとする課題］
このように、硬化体を層状に積み重ねてゆく光学的造形
法により製造される造形体は、積み重ねられた硬化体の
各層の間に段差が生じるため、その表面が平滑面ではな
く凹凸面となる。[Problems to be Solved by the Invention] In this way, the shaped body manufactured by the optical modeling method in which cured bodies are stacked in layers has a difference in level between each layer of the stacked cured bodies, so that the surface of the shaped body is becomes an uneven surface instead of a smooth surface.
即ち、例えば第２図の１部の拡大図である第１図（ａ）
に示す如く、順次積み上げ位置をずらすように積層され
た硬化物２４ ａ、 ２４ ｂ、 ２４ ｃにおいては
、それぞれの硬化物間に段差状の隅角部がある。That is, for example, FIG. 1(a) is an enlarged view of a portion of FIG.
As shown in the figure, in the cured products 24 a, 24 b, and 24 c stacked one after another so that the stacking positions are shifted, there are stepped corner portions between the respective cured products.

化物の上面側が広くなる台形断面形状になり易い。Furthermore, the vertical cross-sectional shape of the cured product 24 is not completely rectangular, and the cross-sectional shape that is irradiated with light is often an expanding trapezoid or triangle. (In a modeled object produced by the apparatus shown in FIG. 2 in which light is irradiated from below, the cured material 24 of each layer has a trapezoidal cross-sectional shape that widens downward as shown in FIG. 1. In an optical shaping device (not shown) that irradiates light from above, the cured product tends to have a trapezoidal cross-sectional shape that is wider on the upper surface side.
このようなことから、硬化物２４を積層してなる造形体
は、その側面に多数の微細な凹凸（第１図の符号ａは凹
部を示す。）を有したものとなっていた。そして、従来
の光学的造形法で製造される造形体は、この凹凸表面で
の光の乱反射のためにスリ硝子の如く透明感の乏しい造
形体となっていた。For this reason, the shaped body formed by laminating the cured material 24 had a large number of fine irregularities (the symbol "a" in FIG. 1 indicates a concave part) on its side surface. The shaped bodies manufactured by conventional optical shaping methods have poor transparency, like ground glass, due to the diffuse reflection of light on the uneven surface.
このような凹凸の存在のために不透明体とされている造
形体を透明化する方法としては、造形体の表面を適当な
方法で研磨することにより段差Ａをなくし、平滑表面と
する方法も考えられるが、この方法は、研磨に多大な労
力を要し、工業的に有利な方法とはいえない。As a method of making a shaped object transparent due to the presence of such unevenness, it is also possible to polish the surface of the shaped object using an appropriate method to eliminate the step A and make it a smooth surface. However, this method requires a great deal of effort for polishing and cannot be said to be an industrially advantageous method.
本発明の目的は、このような従来の光学的造形法で製造
された不透明な造形体を容易に透明化することができる
方法を提供することにある。An object of the present invention is to provide a method that can easily make an opaque shaped object manufactured by such a conventional optical modeling method transparent.

It is characterized by applying a transparent resin liquid and curing it.

を透明化することが可能とされる。[Function] According to the method of the present invention, the unevenness on the surface of the shaped body manufactured by the optical shaping method is filled with the cured product of the resin liquid, resulting in a smooth surface. Therefore, according to the present invention, it is possible to make a shaped object transparent.
［実施例］ 以下、本発明につき詳細に説明する。[Example] Hereinafter, the present invention will be explained in detail.

。In the present invention, for example, after a shaped body manufactured by the optical modeling method shown in FIGS. 2 to 4 is cleaned by spraying or pouring a solvent as necessary, a transparent layer is applied to the surface of the shaped body. Apply resin liquid. As a method for applying the transparent resin liquid, in addition to coating methods such as spraying and brush coating, a method of immersing the shaped body in the resin liquid can be adopted.
なお、造形体を上記の如く洗浄する場合において透明樹

液の付着とを同時に行なうことができる。Note that when cleaning the shaped object as described above, when the viscosity of the transparent resin liquid is low, the transparent resin liquid may be used as the cleaning liquid. In this way, cleaning and adhesion of the transparent resin liquid can be performed at the same time.

化させることができる。The amount of the transparent resin liquid may be such that the recesses a on the surface of the shaped object are filled with the resin liquid and a smooth surface is obtained. If an excessively large amount of resin liquid adheres to the surface of the shaped object, the dimensions and shape of the shaped object may change. (However, if the resin liquid can be applied in a uniform thickness like paint, the transparent resin liquid may be applied thickly.) In the present invention, the resin liquid attached to the surface of the modeled object as described above can be applied thickly. Let it harden. If the resin liquid used is a photocurable resin liquid, the resin liquid is cured by irradiating it with light. Furthermore, when the resin liquid is a thermosetting resin liquid, it can be heated and cured using a suitable heating device such as an oven.
このようにして、付着させた樹脂液を硬化させることに
より、第１図（ｂ）に示す如く、造形体表面の凹部が樹
脂液の硬化物すにより埋められ、滑らかな表面となるの
で、造形体が透明となる。By curing the attached resin liquid in this way, the recesses on the surface of the object are filled with the hardened resin liquid, resulting in a smooth surface, as shown in Figure 1(b). The body becomes transparent.
本発明では、この硬化物すの屈折率が硬化物２４とほぼ
等しい値となるような透明樹脂液を用いると、造形体の
透明度が一層高いものとなる。In the present invention, when a transparent resin liquid is used such that the refractive index of the cured product is approximately the same as that of the cured product 24, the transparency of the shaped object becomes even higher.

溶剤で希釈した液を用いるのが有利である。即ち、造形
に用いる光硬化性樹脂は高粘性であるため、これを適当
な粘度に希釈して用いる。As the transparent resin liquid to be applied to the cured body of such a photocurable resin, liquids such as photocurable resins and thermosetting resins can be used. As mentioned above, this transparent resin liquid is preferably one whose cured product has approximately the same refractive index as the cured product of the curable resin. Since the refractive index of the photocurable resin is usually about 1.4 to 1.6, a transparent resin having a refractive index of approximately 1.4 to 1.6 is appropriately selected. Generally, it is advantageous to use a solution obtained by diluting the photocurable resin used for modeling with an appropriate solvent. That is, since the photocurable resin used for modeling has a high viscosity, it is diluted to an appropriate viscosity before use.
なお、造形に用いる光硬化性樹脂が低粘性のものであれ
ば、これをそのまま使用することもできる。Note that if the photocurable resin used for modeling has low viscosity, it can be used as is.
本発明では、造形体表面に付着させる樹脂は無職透明で
