光性樹脂液９の硬化を行う。First, the personal computer 11 calculates a group of slice graphic data equally spaced in the height direction based on the input three-dimensional graphic CAD data. Next, move the Z axis of the 3D NC table 12,
The base plate 14 fixed to the support rod 13 is attached to the container 19
The photosensitive resin liquid 9 is installed directly below the upper surface of the photosensitive resin liquid 9 inside. and,
Using the contour figure data of the bottom surface calculated by the personal computer 11, the three-dimensional NC table 12 is moved in the x and y axis directions to cure the photosensitive resin liquid 9.

薄膜状のモデル１０しか形成されない。このため厚みの
ある外壁などを生成する場合、必要な領域を塗りつぶす
必要がある。Laser light used for curing is output from an ultraviolet laser 15 and turned on and off by an optical shutter 16. Further, the light is bent downward by 90 degrees by a mirror 17 and condensed by a lens 18 . Since the diameter of the focused laser beam is on the order of microns, only a thin film model 10 is formed in the traveling direction of the laser beam in one scan. 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
レート１４を１層分下降して次層の硬化を行う、この操
作を繰り返してモデルＩＯの形成を行う。The bottom layer is cured as described above, and then the base plate 14 is lowered by one layer to cure the next layer. This operation is repeated to form the model IO.

必要とするという欠点があった。The conventional three-dimensional model molding machine described above focuses the ultraviolet laser beam with a lens and makes it have a diameter on the micron order, so only a thin film-like cured product is formed in 14 scans, and thick outer walls etc. 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
厚くなり、なめらがな曲線を形成することができないと
いった欠点があった。In addition, because conventional three-dimensional model molding machines focus the laser light using lenses, they have the disadvantage that it is difficult to control the thickness of each layer, making it thicker, and making it impossible to form a smooth curve. was there.

う欠点があった。In addition, the conventional three-dimensional model molding machine, after curing the -layer,
It is necessary to add the next layer of photosensitive resin, and it is necessary to wait until the top surface of the photosensitive resin is stabilized.Furthermore, if there is vibration, the top surface will ripple and the model cannot be cured properly.

プ８の紫外線を透過させ感光性樹脂液９を硬化させる。First, a group of slice graphic data equally spaced in the height direction is calculated using the three-dimensional graphic CAD data held by the control unit 5. Next, a photosensitive resin liquid 9 is put into the container. Next, the Z-axis moving table 2 is moved to align the plane light from the lens 3 with the innermost bottom surface of the container 6. Then, as shown in FIG. 2, a voltage is applied to the liquid crystal panel 7 to transmit the ultraviolet rays from the ultraviolet lamp 8 to form the photosensitive resin liquid 9 so that the figure is similar to the surface data of the bottom surface calculated by the control unit 5. Let it harden.

Subsequently, the Z-axis moving table 2 is raised by one layer and the next surface is cured. By repeating this operation, a model 10 as shown in FIG. 3 is finally formed.

るという効果がある。The three-dimensional model molding machine of the present invention does not need to add photosensitive resin after curing one layer, so it can be cured continuously and has the advantage of being able to form in a shorter time than conventional methods. Furthermore, since the layer thickness can be made thinner and it can be cured continuously, it has the effect of making it possible to form a model with a smoother curve than before.
