ABSTRACT:
A method of manufacturing electrically conductive elements such as electrodes for EDM, ECM or other electromachining processes comprises the steps of designing a digital representation of the element, making a three-dimensional replica of the element from an intermediate material, e.g. a polymer, based on the digital representation, and coating the replica with a layer of a good electrical conductor. The replica is made using a tool-less prototyping process. The method is faster and less expensive than conventional machining of copper or graphite EDM or ECM electrodes, especially those having an intricate shape.
