ABSTRACT:
A three-dimensional structure forming apparatus for forming an optical three-dimensional structure by sequentially laminating hard resin layers by repeating a hard resin layer forming cycle by irradiating the surface of a liquid photosetting resin with a light beam including a main resin tank which contains liquid photosetting resin and has a liquid level control so as to maintain the liquid level of the photosetting resin constant. A replenishing tank and a resin supply, supply resin to the main resin tank at a predetermined rate so that the resin continuously overflows the main resin tank.
