The present disclosure relates to a system for making an electrically conductive battery component. The system uses a metal layer forming a planar metal substrate, and a powder deposition component for applying a powder to form a powder layer on the planar metal substrate. A laser is used and configured to generate a laser beam to selectively sinter portions, or all, of the powder layer using a predetermined beam scanning pattern. A subsystem is used to remove portions of the powder layer that are not sintered by the laser to leave a planar finished material layer.
