Abstract

The present invention relates to a method for functionalizing a workpiece surface, comprising the following steps: a) providing a workpiece; b) providing a film; c) functionalizing at least one film side by the location-selective application of a functionalization composition comprising a polymer material onto part of the film side in one or more layers by means of a 3D printing process; d) creating an integrally bonded or interlocking connection between the workpiece surface and the film functionalized in step c) by bringing the film into contact with at least part of the workpiece surface, wherein the integrally bonded or interlocking connection to the workpiece surface is achieved with a functionalized film side. The invention further relates to workpieces having a surface functionalized according to the invention.
