Title: THREE-DIMENSIONAL SHAPING DEVICE
Abstract:
Provided is a three-dimensional shaping device by which a streak in a shaping direction is hardly formed on a surface of a product shaped article in a boundary region of a projected region of an exposure image. A container retains photocuring liquid resin material. A first projector causes a first exposure image to be incident on an incident surface to be projected into the resin material. A second projector causes a second exposure image continuing to the first exposure image to be incident on the incident surface to be projected into the resin material. A control unit adjusts a boundary region on a projected surface of a first projection image obtained by projecting the first exposure image with the first projector and a second projection image obtained by projecting the second exposure image with the second projector.
