Abstract:
1. A process for producing a spatially shaped carrier layer from hard brittle material, comprising: providing a basic mold having a spatially shaped surface; depositing a material which is in the gas or liquid phase on the spatially shaped surface; solidifying the material which has been deposited on the spatially shaped surface to form a hard brittle material layer; and separating the hard brittle material layer from the spatially shaped surface to obtain the carrier layer of hard brittle material; wherein depositing the material comprises depositing liquid phase material on the surface of the basic mold by melt spinning, wherein the basic mold comprises a rotating structured roller, and comprising applying the liquefied material to a cooled surface of the structured roller through a discharge nozzle in the form of a widened let sheet of material, the liquefied material cooling and solidifying and being peeled off the structured roller as a result of the rotation of the structured roller in the form of a solidified, structured carrier layer.
