Abstract
A method of manufacturing an ink jet printing module can include forming a piezoelectric element having a stiffened surface.
Claims36
A method of manufacturing an ink jet printing module comprising:
- injection molding a precursor into a mold to form a stiffened piezoelectric element;
- and
- positioning the piezoelectric element over an ink chamber to subject ink within the chamber to a jetting pressure upon applying a jetting voltage.
A method of depositing ink comprising:
- delivering ink to an ink chamber;
- and
- applying a jetting voltage across a first electrode and a second electrode on a face of a stiffened piezoelectric element to subject ink within the chamber to a jetting pressure, thereby depositing ink from an exit orifice of the ink chamber.
An ink jet printing module comprising:
- an ink chamber;
- a stiffened piezoelectric element having a region exposed to the ink chamber, the piezoelectric element being positioned over the ink chamber to subject ink within the chamber to jetting pressure;
- and
- electrical contacts arranged on a surface of the piezoelectric element for activation of the piezoelectric element.
