パソコン13で計算した最下面の輪郭図形データを用い
、3次元NCテーブル1.5をx、y軸方向に動かし、
感光性樹脂液18の硬化を行う。First, the personal computer 13 calculates a group of slice graphic data equally spaced in the height direction based on the input three-dimensional graphic CAD data 14. Next, the two axes of the three-dimensional NC chiffle 15 are moved, and the base plate 17 fixed to the support rod 16 is installed directly below the two sides of the photosensitive resin liquid column 8. and,
Using the contour figure data of the bottom surface calculated on the computer 13, move the three-dimensional NC table 1.5 in the x and y axis directions,
The photosensitive resin liquid 18 is cured.

要がある。The laser light used for curing is output from the ultraviolet laser 19, the optical shutter 20 is turned off, and the mirror 2 is turned off.
1, the light is bent downward by 90° and condensed by a lens 22. Since the diameter of the focused laser beam is on the order of microns, only a thin film model 23 is formed in the traveling direction of the laser beam in one operation. For this reason, when creating a thick outer wall, etc., it is necessary to fill in the necessary areas.
以上のようにして最下層の硬化を行い、続いてベースプ
レー1〜]7を1層分加工して次層の硬化を行う。この
操作を繰り返してモデル23の形成を行う。The bottom layer is cured as described above, and then one layer of base plays 1 to 7 is processed and the next layer is cured. This operation is repeated to form the model 23.

要とするといった欠点があった。The conventional three-dimensional model molding machine described above focuses ultraviolet laser light with a lens to create a diameter on the micron order, and only a thin film-like cured product is formed in one operation, making it difficult to create thick outer walls. When producing a cured product, it is necessary to fill in the required area, which has the disadvantage of requiring a long time to form a cured product.
また、従来の3次元モデル成形機はレーザ光をレンズで
集光させているので、−層分の厚さの制御が困難なため
層が厚くなり、なめらかな曲線を形成することかてきな
いといった欠点があった。In addition, since conventional 3D model molding machines focus the laser beam with a lens, it is difficult to control the thickness of each layer, which results in thicker layers and makes it difficult to form smooth curves. There were drawbacks.

次に、どのように3次元モデルを形成するかを説明する
。まず、制御部2か持っている3次元図形CADデータ
により、高さ方向に等間隔のスライス図形データ群を計
算する。次に容器3の中に感光性樹脂液11を入れる。Next, how to form a three-dimensional model will be explained. First, a group of slice graphic data equally spaced in the height direction is calculated using the three-dimensional graphic CAD data that the control unit 2 has. Next, the photosensitive resin liquid 11 is put into the container 3.
次にZ軸移動テーブル4を動かし、レンズ5で集光され
た平面光を容器3内側の最下面と一致させる。そして、
第2図に示すように、制御部2で計算した最下面データ
と同様の図形になるように、液晶パネル9に電圧を与え
、硬化させたい場所に紫外線ランプ10の光を透過させ
、感光性樹脂液11を硬化させる。Next, the Z-axis moving table 4 is moved to align the plane light focused by the lens 5 with the lowermost surface inside the container 3. and,
As shown in FIG. 2, a voltage is applied to the liquid crystal panel 9, and the light from the ultraviolet lamp 10 is transmitted through the area to be cured so that the figure is similar to the bottom surface data calculated by the control unit 2. The resin liquid 11 is cured.
感光性樹脂液11は、液晶パネル9を透過した光とレン
ズ5により平面集光された光とが当った所のみ感光する
ものを用いる。The photosensitive resin liquid 11 used is one that is sensitive only to the areas where the light transmitted through the liquid crystal panel 9 and the light focused on a plane by the lens 5 hit.

。また、硬化する面と液晶パネル面の距離が一定なので
、硬化が安定するという効果がある。Subsequently, the Z-axis moving table 4 is raised by one layer, and the next surface is cured. By repeating this operation, a model 12 as shown in FIG. 3 is formed. Note that in the three-dimensional model molding machine of this example, the liquid crystal panel is placed in a photosensitive resin liquid, but only the areas where the light transmitted through the liquid crystal panel and the light focused on the plane by the lens hit are exposed to light. Therefore, it will not harden on the liquid crystal panel surface (bottom surface of the glass case). Furthermore, since the distance between the surface to be cured and the liquid crystal panel surface is constant, there is an effect that the curing is stable.
