Abstract
A mold having a desired print head shape includes a cover in which a plurality of rods or ductile fibers are attached, the cover being positioned with the rods extending into the mold and to the side opposite the cover. A hardenable synthetic material is introduced through a hole in the cover and after hardening of the material to form the print head, the rods are withdrawn from the mold to leave bores or apertures in the print head which serve as passageways for the droplets of ink.
