Abstract

The invention relates to a device and a method for the production of three-dimensional objects, in particular of at least parts of dental prosthetic restorations, by a stripping device wiping off plastic material, which protrudes vertically beyond a container, into a collecting container and forms a projection surface. According to the invention, a stripping device and a light source are coupled and simultaneously guided, at a defined distance, across the liquid light-curing plastic material, whereby the stripping device is guided at a defined distance right ahead of the light source and forms the projection surface for the illuminated field of the light source.
