The Development of a Prototype Silicon Nozzle Array for Continuous Ink Jet Printers
A nozzle array with nine orifices (approximately 10*10μm) ejected jets at a velocity of approximately 45 m/s when a driving pressure of 18 bar was applied. The flow, for each of the nozzles, was measured to be around 0.22 ml/min. The nozzle array showed excellent droplet flight stability for all nozzles within the selected stimulation frequency range of 800 to 1200 kHz. The directivity error for the jets was measured in one dimension and the error was found to be below 4 mrad for all jets. It was possible to charge and deflect the jets individually

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.
