Piezoelectric inkjet print heads have dominated in drop-ondemand (DOD) industrial and commercial market for last two decades, because they offer high jetting frequency, long life expectancy, and the ability to jet a wide range of fluids under harsh working conditions.

Emerging market opportunities will require precise fluidic dispensing with tight dimensional and positional accuracy. Uniformity of orifice diameter, orifice plate thickness, and chamber dimensions across the entire print head helps achieve this goal. This paper focuses on some recent developments and discusses the principle of print head operation, modeling and simulation as well as some unique features such as accurate orifice manufacture, replaceable orifice - chamber plates, inert print head bodies, individual orifice jetting performance calibration, 4- inch print width, and a highly flexible design to adapt to a wide range of drop volumes and jetting fluids. Trident's 256 Jet has currently been developed to meet these applications.

  • 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.
