1. A method for producing an electrical power device from subsequently manufactured parts by an additive manufacturing technique, the method comprising:
determining a target spatial distribution for a plurality of physical properties of the electrical power device, the physical properties being at least one of an electrical property and a mechanical property;
forming a part of the electrical power device;
selecting physical properties of at least one subsequent part of the electrical power device corresponding to the determined spatial distribution of the plurality of physical properties; and
forming the at least one subsequent part using the additive manufacturing technique such that the at least one subsequent part is at least partially in contact with the part;
wherein the at least one subsequent part includes an elastic relaxation part that is configured to transfer an externally applied stress into a plastic deformation of the elastic relaxation part.
