Abstract: A three-dimensional laminated product forming apparatus and method for forming a three-dimensional laminated product from a photo-curable liquid by progressively superposing solid laminae one on top of another by photo-curing a surface layer of the photo-curable liquid and converting it to a solid lamina. A product table is provided on which a three-dimensional solid product is built up in progressive steps and which is incrementally advanced into the photo-curable liquid by a specified depth each step. A liquid surface leveling device works as a capillary to draw up a photo-curable liquid by capillary action while it is in contact with the surface of the photo-curable liquid contained in the container.

Abstract: A photo-curable resin composition for use in optical molding for building up a three-dimensional product by scanning a surface of a liquid photo-curable resin with a beam of radiant energy of suitable intensity and wavelength so as thereby to cure and solidify a liquid layer of the liquid photo-curable resin and forming stacked integrated laminae of cured resin as the three-dimensional product comprises a photo-curable resin material curable, a photo-initiator capable of inducing said photo-curable resin to cause a curing reaction with radiant energy and a fluorescent brightener.
