［発明が解決しようとする課題］
上記の如く、この種の光学的造形法においては、第ｎ層
目（ｎは１以上の整数）の硬化層を形成した後、ベース
を所定ピッチ２分だけ移動させ、第ｎ層目の硬化層を未
硬化の光硬化性樹脂で被う必要がある。[Problems to be Solved by the Invention] As described above, in this type of optical modeling method, after forming the n-th layer (n is an integer of 1 or more) hardened layer, the base is formed at a predetermined pitch of 2 minutes. It is necessary to move the n-th cured layer with uncured photocurable resin.
ところで、上記のとッチｐは形成される硬化層の厚さと

光学的造形法においては、硬化物２４の上に未硬化の光
硬化性樹脂１２が流れ込んできて均一厚さに硬化物２４
を被うようになるのに極めて長い時間を要していた。By the way, the above thickness p corresponds to the thickness of the hardened layer to be formed, and is usually 1 mm or less, especially 0.5 mm.
This is an extremely small value of less than mm. Therefore, in the optical modeling method shown in FIG.
It took a very long time for the patient to become covered with the .

１３との間には液面高さ分だけ液圧がかかるから、第３
図の方法に比べると光硬化性樹脂は硬化物２４と透光窓
１３との間隙に流入し易いが、上記ピッチｐが特に狭い
場合にはやはり該間隙間に流入し終るのにある程度の時
間がかかる。In the optical modeling method shown in FIG. 2, a liquid pressure corresponding to the liquid level height is applied between the cured material 24 and the light-transmitting window 13.
Compared to the method shown in the figure, the photocurable resin flows into the gap between the cured material 24 and the transparent window 13 more easily, but if the pitch p is particularly narrow, it still takes a certain amount of time for the photocurable resin to finish flowing into the gap. It takes.
このようなことから、従来法では、ベースを所定ピッチ
移動させた後、光照射を開始するまでの待ち時間が長く
なっており、製造工程の時間も全体として長いものとな
っていた。For this reason, in the conventional method, the waiting time until starting light irradiation after moving the base by a predetermined pitch is long, and the manufacturing process time is also long as a whole.
［課題を解決するための手段］
本発明は、ベースを所定ピッチ移動させた後、光照射を

形法において、前記ベースをピッチ２分だけ移動さ廿る
に際し、まずｐよりも大きなｐ＋１分だけ移動させ、次
にベースを１分だけ戻すようにしたものである。[Means for Solving the Problems] The present invention provides an optical modeling method in which the base is moved by a predetermined pitch and then the cured layers are successively laminated by light irradiation. When moving, the base is first moved by p+1, which is larger than p, and then the base is moved back by one minute.

短かくなる。[Operation] According to the method of the present invention, when the base is moved by p+J2, the photocurable resin quickly flows onto the cured product or between the cured product and the light-transmitting window. Since the base itself can be quickly moved by a drive device, according to the present invention, after forming the n-th layer, the base is moved by a predetermined pitch of 2 minutes to form the (n+1)-th layer.
The time required to start light irradiation for layer formation is extremely short.
［実施例］ 以下、図面を用いて実施例について説明する。[Example] Examples will be described below with reference to the drawings.

あることが認められた。If you move the base 21 in the order of ■ to ■ in this way,
When the lower surface of the base 21 is raised to ■, a gap of a significantly large distance is opened between the cured material 24 attached to the base 21 and the transparent window 13. Therefore, uncured photocurable resin 1
Even if 2 has a considerably high viscosity, the cured product 24
and the transparent window 13. f! As a result of various experiments, in this example, the pitch p was set to 0.1 to 1 m.
When the distance is approximately m, it has been found that it is suitable to set the distance 1 to be at least 1 times the pitch p, particularly 5 to 30 times, especially approximately 10 to 20 times.

も本発明方法を適用できる。Although this embodiment relates to the case where the base 21 is moved when forming the second layer, the base moving method when forming the third layer and subsequent layers can be performed in the same manner. Also, when the lower surface 21a of the base 21 is first brought into close contact or nearly so with the transparent window 13, and the air bubbles attached to the lower surface 21a and the surface of the transparent window 13 are expelled, the base 21 is raised for only 2 minutes. The method of the present invention can be applied.

Light may also be irradiated from. In this case, the base may be gradually moved laterally during the molding process.

のものであっても迅速に硬化物２４ａ上に流入する。FIG. 4 is a base movement diagram when the present invention is applied to the optical modeling method shown in FIG. 3. FIG. 4 shows a state where the sixth layer is about to be formed after a total of five layers of cured material 24 have been formed. In FIG. 4, the upper surface 21b of the base 21
is located at the level of ■ in the figure, and the fifth layer of cured material 24
After (24a) is formed, the base 21 is lowered by 10 degrees p so that the upper surface 21b is at the level of ■, and then the distance ! It is raised by 11 minutes, and the pitch is raised by 2 minutes so that the upper surface 21b is at the level of ■. In the state (■) during this movement, the liquid level 12a of the photocurable resin 12 is
Since there is an extremely wide distance of 1191 minutes between the photocurable resin 12 and the cured product 24a, even if the photocurable resin 12 has a considerably high viscosity, it quickly flows onto the cured product 24a.

Also, when forming the first layer of cured material 24 on the base 21, the upper surface 21b is first made flush with the liquid level 12a, and then the base 21 is lowered by p+j2 minutes, and then raised by 1 minute. You can also do it. If you do this, base 2
It is possible to extremely quickly make the uncured photocurable resin 12 liquid have a uniform thickness on the surface of the photocurable resin 12.

。[Claims] A movable base is provided in a container, a cured product is formed on or under the base by irradiating the photocurable resin contained in the container with light, and then the base is moved to a predetermined position. In an optical modeling method in which the cured product is covered with a photocurable resin by moving at a pitch, the base is irradiated with light, and this process is repeated to stack the cured product to form a target shape. An optical modeling method characterized in that when moving, the base is first moved by a distance p+1 greater than the target movement pitch p, and then returned by an excess movement distance l, thereby moving the base by the target pitch p.
