Abstract:
A method of making an ink jet printer channel member for use in ink delivery comprising the steps of:(a) molding piezoelectric ceramic powders into a slab in the green state having top and bottom surfaces;(b) machining the top and bottom surfaces of the green state slab to form alternating grooves on the top and bottom surfaces of the green state slab which provide peaks and valleys in opposite sides of the green state slab, wherein the valleys in the top surface are aligned with the peaks in the bottom surface;(c) sintering and poling the grooved green state slab;(d) forming electrically conductive surfaces on the exposed top and bottom surfaces of the sintered green state slab;(e) cutting a slot through each of the valleys in the top surface of grooved sintered green state slab; and(f) positioning an orifice plate over the conductive surface on the top peak surfaces of the slotted sintered slab and a substrate on the conductive surface on the bottom peak surfaces to produce the ink jet printer channel member.
