Abstract
A production device having wear and/or manipulation identification is provided. The production device is produced at least for the most part by additive production methods and has a surface. The production device may be constructed as an assembly device, in particular workpiece coordination device, shaping tool or auxiliary technical production device. According to the present disclosure there is provided at least in a region of the surface at least one signal layer which, in an initial state of the production device, is arranged at a predetermined depth below a surface termination layer of the surface and is covered externally by the surface termination layer of the surface. In this instance, the signal layer differs in a visually perceptible manner from the surface termination layer.
