PURPOSE:To make it possible to prevent occurrence of deformation when a cured part is formed by irradiating it with light by forming a solid while a shape-holding part for reinforcement is simultaneously cured and formed and removing the shape-holding part if necessary after forming it. CONSTITUTION:When a cured part is formed by irradiating it with light, a tongue piece 4' is most easily deformed. Therefore, a shape-holding part 5 for reinforcement over the tongue piece 4' and a neighboring part of another end part of a base 2 is prepd. at the same time when a side wall part 3 is cured and formed and then, an upper part 4 being continuously extended to the upper end is cured and formed. Therefore, when the tongue piece 4' is formed, the shape-holding part 5 extended from the base 2 reinforces and holds the tongue piece 4' and prevents the occurrence of deformation of the tongue piece 4' to make an upper part 4 without deformation. It is possible to obtain a solid having a required shape without any deformation by removing the shape- holding part 5 from the thus formed solid 7 by means of a proper method such as cutting. |
