    Patent number: 5238614
    Abstract: A process of fabricating a three-dimensional object from a light curable liquid resin by radiating a light to a surface of the liquid resin to form successive cross-sectional layers of the cured resin superimposed on each other. The process makes it possible to rapidly form on a platform or on a previously cured layer a fresh stratum of a desired thickness to be subsequently cured into the corresponding layer.
