## Abstract

The invention relates to a device for producing products having individual geometries, comprising a substrate carrier device, a material application device for applying material, preferably above the substrate carrier device, which material application device can be moved relative to the substrate carrier device, and a control device which is coupled to the material application device for signaling. According to the invention, the material application device is coupled to an input interface for signaling and for selection of a first or a second application mode, the control device and the application device being designed such as to produce, in the first application mode, a three-dimensional product on the surface of a substrate plate by way of an additive production method, said substrate plate being connected to the substrate carrier device. According to the additive production method, a curable material is applied in consecutive layers, one or more predetermined regions are selectively cured after or during each application of a layer, the predetermined regions being bonded to one or more regions of the underlying layer. The predetermined region(s) is/are predetermined by a cross-section geometry of the product in the respective layer and is/are stored in the control device, and the curable material is applied in a plurality of consecutive layers to produce the three-dimensional product. The control device and the application device are further designed such that in the second mode of application one or more colors are applied to predetermined regions of a print substrate material connected to the substrate carrier device to produce a monochrome or polychrome print.
