Abstract: A three-dimensional stereolithography apparatus includes a stage, a support mechanism to support a film so that the film is opposed to the stage, a pressing mechanism, a supply mechanism, an irradiation unit, a movement mechanism, and a control mechanism. The pressing mechanism presses at least a linear area of the film so that the linear area closest to the stage is formed in the film. The supply mechanism supplies a light-curing material into a slit area formed between the stage and the linear area. The irradiation unit irradiates the light-curing material supplied into the slit area with laser light through the pressing mechanism and the film. The movement mechanism moves the stage and the pressing mechanism relatively to the film, to form one cured layer of the light-curing material. The control mechanism controls a distance between the stage and the linear area of the film, to stack the cured layer.
