A newly developed ion head architecture for high resolution ionographic printing, with a spot size capability of ∼100 μm, utilizes a dielectric barrier discharge (DBD) to produce an atmospheric pressure plasma that is the source of the charge. The DBD is produced using a radio frequency (rf) voltage and extracted with biased electrodes having designs which focus the charge. To aid in the development of the ion head and interpretation of experiments, a first principles program of multi-dimensional computer modeling of the ion head devices has been conducted. Results from the model will be discussed showing the dependence of the magnitude and shape of extracted charge from the ion head and current waveforms as a function of driving voltage and frequencies of the rf excitation, dielectric materials and geometry of the head.

More about this publication?
  • 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.
