1. A method for forming a multi-material electromagnetic shield comprising:
providing at least one powderized feedstock of a magnetic alloy;
determining at least one printing parameter for an additive manufacturing process;
depositing the at least one powderized feedstock in a vertical orientation using the determined at least one printing parameter to additively manufacture an electromagnetic shield with at least one shield wall; and
post-processing the electromagnetic shield by at least one of stress relief anneal, hot isostatic pressing, full anneal, and surface finishing;
wherein the at least one powderized feedstock is delivered by at least one powder feeder;
wherein the additive manufacturing process uses a laser as a power source;
wherein the deposition is in a chamber filled with an inert gas; and
wherein the thickness of the at least one shield wall is controlled by a spot size of the laser.
