形状を直感的に把握し、充分に理解し得るには必ずしも
満足し得る技法とは言えない。As methods for displaying three-dimensional stereoscopic information, stereoscopic display using holography, perspective view display, projection view display, contour line display, etc. have been developed and are generally widely used. With the exception of holography, all of these methods can convert three-dimensional information into two
It includes a procedure for converting into dimensional information, and is not necessarily a satisfactory technique for intuitively grasping and fully understanding the displayed three-dimensional shape.

ことが困難で有る。In this respect, the holography is visually and intuitively more advantageous than the above techniques, but it requires a reproduction device to obtain a three-dimensional shape, and it is difficult to display non-existent virtual objects. .
このようなことから立体情報を直感的に把握し理解し易

模型形状を積層状に形成する方法が提案されている。For this reason, in order to grasp 3D information intuitively and display it in an easy-to-understand manner, it is best to create a 3D shape such as a model. A photocurable resin material is supplied into a container in stages, and each time the resin material is supplied, the photocurable resin material is selectively photocured using a laser beam irradiation means or the like to form a complex three-dimensional model shape in a layered manner. A method has been proposed.
しかしこのような従来の形成方法にあっては、光硬化型
樹脂材を段階的に供給するのに、オーバーフロ一方式を

望されている。However, in such conventional forming methods, an overflow method is used to supply the photocurable resin material in stages, which requires a long time for supplying and reduces the total forming process time. There are problems that greatly affect this, and there is a desire to shorten the resin supply time.

材４をオーバーフローさせることにより供給する。Conventionally, as a method of forming a model shape that displays three-dimensional stereoscopic information by using a photocurable resin material using a laser beam irradiation means, as shown in FIG. 7, a liquid photocurable resin material 3 is filled. The elevating support table 2 in the storage container 1 is lowered by a predetermined distance, and one portion of the photocurable resin material 4 is supplied by overflowing onto the elevating support table 2.

Beam 5 or photocurable resin material 4 side
, beam irradiation is performed by moving and scanning in the Y direction, and selectively exposing and curing to form the first cured resin Ff4a.

A new second layer of photocurable resin material 6 is supplied on top of a in the same manner as above, and the photocurable resin material 6 is similarly exposed to the laser beam 5 by the second information pattern signal as shown in FIG. is selectively exposed and cured to form a second cured resin layer 6.

いる。This three-dimensional cured resin image is taken out from the liquid photocurable resin material 3, and by washing away the liquid photocurable resin material 3 with a dilute alkaline cleaning solution, a desired three-dimensional solid is created as shown in FIG. A model shape 8 for displaying information is being created.

樹脂面を得るのに該液状光硬化型樹脂材３０粘度との関
係と相俟って、かなりの供給時間を必要としている。However, the method of supplying the liquid photocurable resin material 3 in the above-mentioned forming method is such that the liquid photocurable resin material 3 is supplied onto the elevating support 2 that has been lowered by a certain amount, or onto the cured resin layer 48 or 6a that has already been formed on the elevating support 2. As shown in FIGS. 8 and 10, the liquid photocurable resin material 4 or 6 is supplied by the so-called overflow method, in which it flows naturally. Coupled with the relationship with the viscosity of the photocurable resin material 30, a considerable supply time is required.
従って、上記のように立体形状を積層状に形成する場合
には、該液状光硬化型樹脂材３の全供給時間が、−要分
の樹脂材供給時間の層数倍となり、全形成工程時間に大
きく影響する問題がある。Therefore, when forming a three-dimensional shape in a layered manner as described above, the total supply time of the liquid photocurable resin material 3 is - the number of layers times the resin material supply time for the essential resin material, and the total forming process time is There is a problem that has a big impact on

成工程の高速化、高精度化に大きな障害となっている。In addition, as the viscosity of the liquid photocurable resin material 3 increases, not only does the supply time increase, but it also becomes difficult to control the thickness of each liquid photocurable resin layer, which slows down the formation process. This is a major obstacle to increasing speed and precision.

樹脂材供給時間が異なり、当該立体形状の全形成工程の
制御が容易でないといった欠点があった。Furthermore, when supplying the liquid photocurable resin material 3 onto the cured resin layers 4a and 6b that have already been exposed and cured, since the volume or surface area of each cured resin layer is not constant, the supply of the resin material every time each resin layer is formed. There were disadvantages in that the time required was different and that it was not easy to control the entire process of forming the three-dimensional shape.
