Abstract:

Periodic behaviors in a piezoelectric line ink jet printhead are studied. The printhead is composed of a monolithic structure having resolution of 600dpi in 4.25 inch effective print width. The structure is made up of plural metal foil layers, in which parts of channels are formed respectively, and actuator units mounted on top of them. The nozzles opened in the bottom layer are lead from cavities underneath of the actuator units through a descendant conduit named descender. Analyses on experiments suggest that a descender, cavity and unimorph actuator could make an individual acoustic element, of which acoustic period is much shorter than that oft the discharging unit.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
