Abstract: Some aspects of the invention may be directed to a system and a method of manufacturing a laminated three-dimensional (3D) metallic object. The method may include: providing a plurality of foils of metal; marking portions of some of the foils in the plurality of foils with a marking agent that may include a material having electrochemical potential higher than the metal; bonding the plurality of marked foils into a block; and selectively etching parts of the block not in proximity to the marking agent. Laminated 3D metallic objects are provided which comprise periodically diffused marking material into the metal layers, e.g., at low concentration.
