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 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
