Description

The present invention relates to a shaped object and a method for manufacturing a shaped object.

Conventionally, for example, a figure's facial expression (eyes, eyelashes, etc.) has been a very important part in determining the value of the figure as well as influencing its facial expression. For example, Patent Document 1 describes a method of manufacturing eyeballs for dolls, in which a contact body such as an elastic silicone resin is pressed against a coating film that simulates the iris of an eyeball by printing, and the attached coating film is removed from the eyeball. A technique for transferring the image onto a spherical surface imitating the spherical surface is described. In this way, the iris pattern formed by printing can be formed on the eyeball surface by transfer of the coating film, and the iris can be expressed with high precision.

JP2012-24382A

However, if an attempt is made to represent the eye by printing, there is a risk that the print will be misaligned with respect to the eyeball surface. In products such as the face of a figurine, where even the slightest misalignment of the face-expressing members causes a sense of discomfort, misaligned eyeballs can impair the value of the product.

Furthermore, in the case of plastic model figures that require the user to partially assemble, the eyes and face of the figures have traditionally been expressed using stickers. However, it takes time for the user to apply the sticker, and the sticker may be misaligned, and it is difficult for the user to achieve a satisfactory finished product because it requires skill to apply the sticker in a way that does not feel strange.

The present invention provides a shaped object that can easily form an eye expression with high precision.
