PRODUCTION OF SEAMLESS BELT

摘要

PROBLEM TO BE SOLVED: To obtain a seamless belt high in shaping accuracy within a short time by repeating a process irradiating a liquid photo-setting resin layer supplied to a housing container in a predetermined thickness to selectively cure the same and curing the resin layer on the basis of the cross section data of the three-dimensional shape of a seamless belt. SOLUTION: A liquid photo-setting resin material 12 is housed in a container 16 and selectively irradiated with a light having a pattern corresponding to the cross-sectional shape of a seamless belt to form a cured resin layer having a predetermined thickness. Next, the cured resin layer is moved in a vertical direction to newly supply the layer of the liquid photo-setting resin material 12 having a predetermined thickness on this resin layer. This new resin material layer is selectively irradiated with light having a pattern successively changed corresponding to the cross-sectional shape of the seam belt to form a new cured resin layer having a predetermined thickness on the cured resin layer. These processes are repeated to be continued until the three-dimensional shape of the seamless belt is shaped as a laminated type three-dimensional cured resin molded object 17.
