A technique is described whereby wires, used as electrodes in electro- erosion printers, are fabricated in such a way so as to resist bending and breakage. The concept changes the grain structure of the wire, used as the electrodes in the printer, by applying radio frequency (RF) heating combined with chemical vapor deposition to produce extremely strong and stiff wire electrodes from small-diameter wire. The print resolution of the electro-erosion printer is dependent upon the diameter of the tungsten wires used as electrodes, typically .003" IN DIAMETER. SMALLER DIAMETER WIRES ARE NOT STIFF ENOUGH TO resist bending and breaking.
