Abstract: A piezoelectric ink jet printhead is formed from two rectangular blocks of PZT material each having interdigitated series of grooves and ribs formed on one side thereof. The blocks are relatively positioned to precisely align the outer sides of their rib portions in a facing relationship to form a printhead body having therein a spaced series of ink receiving channels defined by the facing groove portions of the two blocks and laterally bounded by internal sidewalls defined by the aligned rib portions of the blocks. The channels open outwardly through front and rear end portions of the body. An orifice plate is operatively secured over the front ends of the channels, and the rear ends of the channels are appropriately sealed.
