（照射装置）が設けられている。In FIG. 2, a photocurable resin 12 is housed in a container 11. As shown in FIG. A transparent window 13 made of a transparent plate such as quartz glass is provided on the bottom of the container 11.
The light emitting unit 15 containing a built-in lens, the optical fiber 16, and the light emitting unit 15 are moved in the X-Y direction (x and y are two orthogonal directions) in a horizontal plane so as to irradiate the light beam 14 toward 3. - An optical system (irradiation device) consisting of a yg motion device 17, a light source 20, etc. is provided.

われる。When producing a cured body using the above device, first the base 21
is positioned slightly above the transparent window 13, and the light beam 14 is scanned along the horizontal cross section of the target object. This scanning is performed by a computer controlled x-y movement device 17.

。After irradiating the entire horizontal cross section of the target shape (in this case, the part corresponding to the bottom or top surface), the base 2
1 is slightly raised to flow uncured photocurable resin between the cured material (cured layer) 24 and the light-transmitting window 21, and then the same light irradiation as above is performed, and this procedure is repeated. As a result, a cured product having the desired shape is obtained by binding a multilayer laminate.
［発明が解決しようとする課題］
上記光学的造形装置においてはベース２１を引き上げた
際に硬化物２４が透光窓１３から離反することが必要で
ある。即ち、硬化物２４がベース２・１から引き剥され
てしまったのでは造形工程を継続することがで台ない。[Problems to be Solved by the Invention] In the optical modeling apparatus described above, it is necessary that the cured product 24 separates from the transparent window 13 when the base 21 is pulled up. That is, if the cured product 24 is peeled off from the base 2.1, it will be impossible to continue the modeling process.

２４との付着性（なじみ）が低く、ベース２１を引き上
げると硬化物２４は透光窓１３から簡単に引き剥され、
硬化物２４はベース２１に常時、付着保持されるように
なる。For this reason, conventionally, a resin coating layer such as a fluororesin is formed on the surface of the light-transmitting window 13 on the inner surface of the container. This resin coating layer has low adhesion (compatibility) with the cured product 24 made of the photocurable resin, and when the base 21 is pulled up, the cured product 24 is easily peeled off from the transparent window 13.
The cured product 24 is always adhered to and held on the base 21.
ところが、この樹脂被覆層が光束１４に長時間暴露され

して長時間性なわれる場合に発生し易い。However, when this resin coating layer is exposed to the light beam 14 for a long time, the resin deteriorates or minute irregularities are formed on the surface of the resin, and the adhesion between the cured product 24 and the resin coating layer decreases. increase As a result, the cured material 24 may be peeled off from the base 21 when the base 21 moves upward. Such deterioration of the resin coating layer occurs when localized light beam irradiation is continued for a long time, such as when a long cylindrical member is grown in the longitudinal direction of the cylinder by laminating disk-shaped cured products. Easy to occur.

ものである。[Means for Solving the Problems] The present invention irradiates light from a light-transmitting window with a resin coating layer of a container and gradually moves the base away from the light-transmitting window, thereby producing a photocurable material corresponding to the cross section of the object shaped body. In an optical modeling method in which a desired shape is formed by laminating many cured layers of a transparent resin, when the cured layer (cured material) is separated from the light-transmitting window, the light-transmitting window is moved toward the window surface. It was moved to .
［作用］
かかる本発明方法にあっては、透光窓の同一箇所に集中
的に継続して光束が照射されることが回避される。[Function] According to the method of the present invention, it is possible to avoid irradiating the same portion of the light-transmitting window with the light beam in a concentrated and continuous manner.
この結果、樹脂被覆層の劣化が防止されるようになる。As a result, deterioration of the resin coating layer can be prevented.

A hardened layer 24 is formed. Next, after the base 21 is roughly moved away from the transparent window 13 by a predetermined distance by the elevator 22, the motor 36 is driven to rotate the container 11 around the axis A by a predetermined angle. Thereafter, light is irradiated again to form a second hardened layer 24.

Since the cured N24 of the n+1 layer is formed after rotating the base 21, even if the n+1 layer and the n+1 layer have the same shape and are formed at the same position with respect to the base 21, The light from the light emitting section 15 passes through different parts of the transparent window 13 when forming the nth layer and when forming the (n+1)th layer. (However, this excludes the case where the n-th layer and the n+1-th layer are circular layers of the same shape concentric with the axis A. In this case, the center of the XY moving device and the center of the container rotation axis are set to be different. ) Therefore, the resin coating layer of the transparent window 13 is prevented from being locally concentrated and irradiated with light.

的造形法。[Scope of Claims] A container having a light-transmitting window on the side or bottom surface, a base movable toward and away from the inner surface of the container of the light-transmitting window, and a light that irradiates light into the container through the light-transmitting window. Using an optical modeling device equipped with an irradiation device, light is irradiated through the transparent window and the base is gradually moved in a direction away from the window, so that a hardened layer corresponding to one cross section of the target shape is placed on the base. In an optical modeling method in which a target shape is formed by stacking the transparent window on the inner surface of the container, a resin coating layer is provided on the inner surface of the container, and when the cured layer is separated from the transparent window. An optical modeling method characterized by moving a translucent window in the direction of the window surface.
