Together with a high level of stability, the magnetic efficiency, in particular, of rotor metal sheets is to be increased. For this purpose, an electric metal sheet is provided for an electric machine, the main body of which is an individual sheet made of a magnetizable material, the individual sheet having a plurality of cut-outs. At least one web is provided in one of the cut-outs, the web being printed by a 3-D printing method from a non-magnetizable material.
