In this paper, a novel continuous inkjet technology will be presented. The technology presented uses a pulsed application of asymmetric heat to a pressurized stream of ink emitted from a nozzle both to break up the stream into regularly sized printing drops and to deflect the drops onto a receiver while allowing the non-printing drops to be captured. Depending on the nozzle geometry, fluid properties and applied pressure arrays of small drop volumes (3 picoliters) can be jetted and deflected at high velocity (10 m/s). The printhead, fabricated in silicon, is produced by MEMS processing techniques that are CMOS compatible, allowing for direct integration of circuitry. The basic device geometry and operation will be described including some experimental results.

  • 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.
