We are trying to develop a new inkjet printing head with the use of MEMS technology for the Printed Electronics applications. The newly developed print head consists of three layers; a nozzle plate, an intermediate plate, and an actuator. The actuator has an unimorph structure with piezo ceramic element. We investigated the effects of a nozzle-hole shape, structures of a pressure chamber and an ink inlet, and finally achieved to drive the actuator to displace small volume of ink with higher frequency by optimizing them.

We also investigated the effects of the nozzle-hole shape and ink repellency of the nozzle plate to minimize the angle deviation of jetted droplets.

  • 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.
