Abstract

Methods for forming an electrode for use in forming a honeycomb extrusion die. The method includes forming, by means of an additive manufacturing process, an electrode includes a base having a web extending from the base. The web defines a matrix of cellular openings. The method further includes forming a secondary electrode having a plurality of pins. The plurality of pins are shaped and arranged so as to mate with the matrix of cellular openings defined by the web of the electrode. The method further includes machining the electrode using the secondary electrode to smooth surfaces of the electrode formed by the additive manufacturing process.
