A device and production method, in which a workpiece is built up gradually in layers. To build up the workpiece, preformed layers, which are individually formed on a layer support using an electrophotographic printing process are transferred one at a time from the layer support to the workpiece. For this purpose, the layer is transferred to the workpiece in a printing operation, the layer being preferably laid on the workpiece by a die. In one embodiment, a plurality of workpieces are built up simultaneously and a plurality of preformed layers are transferred simultaneously to different respective workpieces. In another embodiment, the layer is formed on the layer support, which is preferably a film or paper, prior to being transferred.
