A fin block is provided for a calibrating device for the calibrating of an extruded plastic profile, wherein the fin block includes a back structure and a fin structure having a plurality of fins. The fins are spaced apart from one another and arranged on the back structure in longitudinal direction (L) of the back structure. The back structure of the fin block has a plurality of apertures, the shape and/or arrangement of which within the back structure depends on a predetermined mechanical load capacity for the back structure. Furthermore, a method for the production of the above-mentioned fin block and a calibrating device, which includes a plurality of the above-mentioned fin blocks, is provided. Furthermore, a system for the additive manufacture of the above-mentioned fin block, a corresponding computer program and a corresponding data set is provided.

A lamella block is provided for a calibrating device for calibrating an extruded profile. The lamella block includes a lamella structure, which has a plurality of lamellae that are spaced apart from each other by grooves and arranged in the longitudinal direction of the lamella block. The lamella structure has two lamella sets, wherein the lamellae of the first lamella set are arranged offset in relation to the lamellae of the second lamella set in the longitudinal direction of the lamella block. Further provided is a method for manufacturing the lamella block mentioned above as well as a calibrating device, which includes a plurality of the lamella blocks mentioned above. Also provided is a system for additively manufacturing the lamella block mentioned above, a corresponding computer program and a corresponding dataset.
