PURPOSE: A rapid stereolithography apparatus is provided to remarkably reduce the lithography time by forming a resin in a required shape at once without using a separate negative mask. CONSTITUTION: A light is radiated into a photo-curable resin(10) so as to form an article. A rapid stereolithography apparatus includes a projector(11) for radiating a light into the photo-curable resin(10), a frame(12) for accommodating the photo-curable resin(10) therein, a stage for fixing the cured photo-curable resin(10), and a signal processing device for allowing the projector(11) to radiate the light in a required pattern. The stage(20) is installed at an upper portion of the frame(12). When the article is formed, the photo-curable resin(10) is lifted upward.
