で、造型体を自動的に成形する。Problems to be Solved by the Invention Development of resource-saving and efficient production technology of the so-called optical molding method Means for solving the problems A photocurable fluid material is spread on a liquid with a higher specific gravity,
Effect of photo-curing operation When a photo-curable fluid substance is in a fluid state, it is spread out on the liquid, but when it is cured, the photo-curing effect starts due to laser light, etc., and when it is cured, the specific gravity increases due to the polymerization effect and the liquid becomes liquid. As it sinks inside, the molded object is automatically formed.

ー光４を照射し、光硬化性流動物質２を硬化させる。Example Container 1 contains a photocurable fluid material 2, specifically, modified urethane methacrylate, epoxy acrylate, photosensitive polyimide, etc.
No. 247515, the container is not directly stored in the container, but
Inside, a substance with a higher specific gravity than the photocurable fluid material 2 is contained in advance,
For example, on liquids 3 with high specific gravity such as glycerin, fluorocarbon-based liquids, and bromine-based liquids! lll11. At this time, there are cases where the difference in specific gravity between the glycerin and the photocurable fluid material to be developed is small, but in such cases, a soluble film such as polyvinyl alcohol, wafer, etc., or a 0. A low-density polyethylene film of O1am or less is developed, and a photocurable fluid material is poured onto it.
The photocurable fluid material 2 is cured by irradiating it with laser light 4 at the required locations in order so as to develop it into a desired shape.
光硬化性流動物質２は硬化とともに比重が増大し、比重
の大きい液体３中に沈下する。As the photocurable fluid material 2 hardens, its specific gravity increases, and it sinks into the liquid 3 having a high specific gravity.
この沈下に従い、光硬化性流動物質２を順次、容器１内
に追加し、所望の形状の物質を得るものである。According to this settling, the photocurable fluid material 2 is sequentially added into the container 1 to obtain a material having a desired shape.
発明の効果
容器内に、光硬化性流動物質より比重の大きい液体が、
予め収容されており、光硬化性物質は、その時点で成形
に必要な量だけを容器内に収容すれば良く、省資源効果
があり、さらに自動沈下するので成形の精密化が連続す
るとともに、比重の大きい液体を、加温することにより
成形能率が向上できる。Effect of the invention In the container, a liquid having a higher specific gravity than the photocurable fluid substance,
Since the photocurable material is stored in advance, only the amount required for molding at that time needs to be stored in the container, which has a resource saving effect.Furthermore, since it sinks automatically, the precision of molding can be continuously improved. Molding efficiency can be improved by heating a liquid with a high specific gravity.
