STEREOLITHOGRAPHY APPARATUS

PROBLEM TO BE SOLVED: To provide a stereolithography apparatus which quickly hardens a curable resin in forming a three-dimensional resin model and does not cause damages on the model being in the forming process. SOLUTION: The stereolithography apparatus produces the three-dimensional model by repeating to form an uncured resin layer with a specific thickness by coating a resin on a photocured layer and to photocure the uncured resin layer so as to stack cured layers one after another. The stereolithography apparatus has: a sweeping device which is provided with a sweeper 23 which is arranged to be movable in parallel with the liquid surface of a photocurable resin, and moves on the liquid surface of the photocurable resin by the sweeper 23; and a bow 25 which forms a shape of an isosceles triangle protruding toward the moving direction; an edge 26 which protrudes toward the moving direction of the sweeping device and is formed at the bottom edge of the bow and second edge 27 which is smaller than the edge and arranged at the edge on the opposite side of the edge.
