A method for producing a molding, the shape of which is adapted to an initial mold, in which method a plurality of layers are deformably placed on top of one another such that the layers can be joined to each other by heat. The layers are deformed by being pressed onto the initial mold and in order to join the layers. Heat is applied in the deformed state. In the arrangement made of layers, at least one converter element is introduced that transforms supplied energy into heat energy and with which at least parts of the layers are heated to join the layers.
