Abstract

A system includes at least one electronic controller configured to generate machine code based on a predetermined component geometry associated with a component and at least one printing device. The system includes a comparison system comprising at least one recording device configured to record a geometry of the component using one of a strip projection routine and a white-light interferometry routine and at least one comparison controller configured to compare the geometry of the component with the predetermined component geometry. When a deviation exceeds a predetermined limit value, the at least one comparison controller is configured to generate modification information and deliver the modification information to the at least one electronic controller. The at least one electronic controller is configured to modify the machine code based on the modification information and to deliver the modified machine code to the printing device.
