Designing and Optimizing New Microchannel Architectures to Approach High Frequency Inkjet
Abstract:This work develops several new designs of micro-channel architectures (arches) and promotes successfully the jetting frequency from commercial 6 kHz to 12 kHz in a large drop weight of 70 ng. These printheads with different arches of ink micro-channel were fabricated to be investigated by the tests and analyses including dot size, circularity, drop appearance, and frequency response of mass-jetted. These arches mainly comprise two stages of channels and provide with various specific features. The results show most of these designs are able to successfully jet weighty drops of 65∼75 ng and keep low change of drop weight while frequency increases over 10 kHz. The characteristics of different features are also evaluated for jetting performance. These new micro-channel designs indicate a new way to approach much higher speed for inkjet printing.

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.
