Optical molding process and optical molding apparatus.

摘要

An optical molding process for obtaining a three-dimensional resin model by scanning a surface of a photocurable resin liquid held in a photocurable resin liquid tank by a light beam to cure the same and successively building up the scanned and cured layers on an elevator. When the molding of one constant-height section layer is ended and the elevator is made to descend, the overflow of the photocurable resin liquid from the photocurable resin liquid tank to an overflow tank is temporarily blocked and then after the blocking of the overflow is lifted, the next constant-height section layer is molded. <IMAGE>
