METHOD OF PHOTOFABRICATION

An object of the present invention is to provide an optical molding method that is capable of taking out the model shape of an optically-molded object with high accuracy, and capable of performing molding with high accuracy even when a shape having a fine structure or a microstructure is molded. An optical molding method to form a three-dimension shape object in which cured resin layers are laminated and integrated includes forming a cured resin layer of a photo-curable composition by irradiating a photo-curable composition layer with light, forming the photo-curable composition layer again above the cured resin layer, forming further a cured resin layer of the photo-curable composition by radiating a light, and repeating these steps, wherein the photo-curable composition layer is formed by applying a photo-curable resin composition containing resin, an ethylenic unsaturated compound, and an organic solvent above a base material or above the cured resin layer formed above the base material, and removing the organic solvent contained in the photo-curable resin composition, and wherein the three-dimension shape object is formed by removing the photo-curable composition that is not cured in the cured resin layers after the formation of all the cured resin layers is completed.
