1. An optical molding process for obtaining a three-dimensional resin model comprising the steps of:
- providing a photocurable resin liquid tank having a supply of photocurable resin liquid therein and an elevator in the photocurable resin liquid tank;
scanning a surface of the photocurable resin liquid accommodated in the photocurable resin liquid tank with a light beam to cure a first three-dimensional layer of the photocurable resin liquid between the surface of the photocurable resin liquid and the elevator;
arranging an overflow tank in flow communication with said photocurable resin liquid tank;
blocking temporarily an overflow of the photocurable resin liquid from the photocurable resin liquid tank to said overflow tank;
making the elevator descend;
releasing blocking of the overflow of the photocurable resin liquid from the photocurable resin liquid tank to said overflow tank; and
molding a next three-dimensional constant-height section layer on said first three-dimensional layer after releasing said blocking of the overflow.

Abstract
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.
