Abstract

A low cost print head suitable for use in an electrolytic printer is implemented by the use of a plastic molded jacket fitted on an electrode to allow interference fit into a conductive carrier assembly, metal or conductive plastics, see the figure (a). The carrier can be developed by various processes, e.g., dye casting, injection molding or sintering. The insulator on the electrode is chosen for low moisture permeability, mechanical strength (compressive) and wear behavior. The conductive carrier acts as the system cathode and is also chosen to have mechanical rigidity, wear characteristics that match with those of the insulator and electrode materials and sufficient conductivity to properly function as a cathode ground.
