The invention relates to a device and a method for producing three-dimensional objects, in particular at least parts of dental prosthetic fixtures, in that a scraping device scrapes off into a collecting container plastics projecting over and above a container and forms a projection surface. In particular, a scraping device and a light source are simultaneously guided at a defined distance over the liquid, light-curable plastics, the scraping device being moved at a defined distance from the light source, directly before it, and forming the projection surface for the irradiation field of the light source.
