Performance of Fluids in a Silicon-based Continuous Inkjet Printhead Using Asymmetric Heating
Abstract:In this paper, we study the performance of a variety of fluids in a new continuous inkjet printhead that employs asymmetrical heating of a jet of fluid to cause it to deflect. The basic design and operation of the printhead is described in a companion paper in this same conference. We focus mainly on the performance of non-aqueous fluids, with some discussion of the performance of water mixed with common humectants.
By examining the performance of a variety of fluids, we try to understand the mechanism causing the deflection. We compare our experimental results to the output of a Computational Fluid Dynamics (CFD) model of the device that is solved using finite difference Volume of Fluid (VOF) code. With our choice of fluids, we focus on the role played by the temperature dependence of the fluid viscosity on magnitude of the jet deflection.

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.
