The Numerical Study on Size Effects of the Inkjet Print Head
Abstract:Increasing printing speed is one of the most-demanding needs for printer users. To achieve this, one should accelerate the ink refill after ink was jetted out. This depends on the proper design of the ink feed path of the print head. The ink feed path consists of nozzle plate, ink chamber, ink feed channel etc. All the shapes and sizes of these parts are important in design process. Nozzle diameter, nozzle plate height, chamber size, feed channel length and height are the key parameters for design. This work used computational-fluid-dynamics (CFD) method to study the size effect of these parts. The numerical schemes, the volume-of-fluid (VOF) method has been used due to its capability to deal with the interface between gas and liquid. Finite volume method is used as basic numerical scheme. The simulation can help engineer to find an better performance of the structure, which is consistent with the experiments.

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.
