A method is provided for producing a composite body made of at least one self-supporting surface and at least one element connected to the surface in a coating process. The method includes providing a negative mold including the at least one element of the composite body, selectively ablating a surface of the negative mold to be coated with the at least one self-supporting surface by a defined first thickness so that the at least one element stands out from the surface as a projection at least in areas, depositing one or more layers for forming the at least one self-supporting surface having a defined second thickness, wherein an elevation forms in the area of the projection of the at least one element, leveling the coated surface, wherein the elevation is removed, and selectively removing at least parts of the negative mold. |

1. Method for producing a composite body from at least one self-supporting first surface and at least one element connected to the at least one self-supporting first surface in a coating process, wherein a negative mold is provided having a diameter with an oversize relative to a diameter of a final dimension of the negative mold, and comprising the at least one element of the composite body, the method comprising:
(a) smoothing the negative mold on an outer second surface as a whole prior to a selective ablation in order to set the at least one element in the negative mold to a required dimension, wherein the outer second surface is adapted to be coated; (b) selectively ablating the outer second surface of the negative mold to be coated with the at least one self-supporting first surface by a defined first thickness such that the at least one element stands out from the outer second surface as a defined projection at least in some areas, wherein the first thickness is between 5 μm and 25 μm; (c) depositing one or more layers for forming the at least one self-supporting first surface having a defined second thickness, wherein an elevation forms in the area of the projection of the at least one element and the projection of the at least one element is embedded in the at least one self-supporting first surface, wherein the at least one self-supporting first surface is formed from a first layer and a second layer, the first layer having a smaller thickness than the second layer, a thickness of the first layer being between around 5-15 μm and a thickness of the second layer being between around 30-50 μm, and wherein a thickness of the at least one self-supporting first surface is less than a sum of the thickness of the first layer and the second layer; (d) leveling of a coated, outer, third surface of the at least one self-supporting first surface, wherein the elevation is removed and the coated, outer, third surface is formed having a homogeneous appearance, (e) selectively removing at least parts of the negative mold.
