The invention relates to a process for the production of a dental model (24). The invention furthermore relates to a dental model which can be produced in this way, optionally with a ceramic layer deposited thereon, a process for the production of a dental moulding, the use of a 3D printer and the use of a kit. According to the invention, the following steps are proposed for the process: (a) provision of one or more fluid, solidifiable materials and one or more electrically conductive substances and (b) production of the dental model (24) by rapid prototyping using the fluid, solidifiable material or materials and the one or more electrically conductive substances, so that the dental model produced is electrically conductive in one or more areas (26, 28, 30) of its surface.
