The invention relates to a process for producing products having a specific geometry, in particular dental prostheses or auxiliary dental parts, comprising the steps of producing a plurality of products on the surface of a substrate plate by selective curing, in particular by selective sintering or melting, wherein the material is applied in successive layers, one or a plurality of predetermined regions are selectively cured by means of high-energy radiation and joined to one or a plurality of regions of the subjacent layer after each application of a layer, wherein the predetermined regions are predetermined according to a cross-sectional geometry of the product in the respective layer. According to the invention, a substrate plate is provided which is subdivided into a first substrate plate segment and at least one further substrate plate segment that are detachably joined to each other or to a base carrier, a first product is produced on the first substrate plate segment by applying successive layers of material onto the first substrate plate segment and selectively curing predetermined regions of each applied layer of material after it has been applied, and at least one further product is produced on the at least one further substrate plate segment by applying successive layers of material onto the further substrate plate segment and selectively curing predetermined regions of each applied layer of material after it has been applied. The invention also relates to an apparatus for conducting such a process.
