摘要： A method for producing a workpiece, includes providing a substrate having a predetermined surface structure; coating the surface structure with a coating material, wherein the coating material is resistant to a production temperature of an additive production method; the additive production of a material for the workpiece on the coated surface structure using the additive production method such that the coated surface structure defines a base surface of the workpiece to be produced, and the detachment of the substrate. A workpiece is produced by the described method.
