1. A method for producing a component of an electric motor, comprising:
forming, via alternate additive production, a layer assembly including first layers and second layers, wherein each first layer includes a filament containing plastic and metal, and each second layer includes a filament containing plastic and ceramic,
heating the layer assembly to a first temperature, at which the plastic is removed from the first layer, and
further heating the layer assembly to a second temperature, at which the metal of the first layer is sintered;
wherein, at the first temperature, the plastic remains in the second layer.
