Design And Evaluation Of A Silicon Based Multi-nozzle For Addressable Jetting Using A Controlled Flow Rate In Electrohydrodynamic Jet Printing

摘要

This letter reports on the development and evaluation of a electrohydrodynamic jet printing that uses an addressable multinozzle. To reduce the interference and distortion in the electric field, a multinozzle was fabricated from a silicon wafer. The experimental conditions were optimized to prevent the jet from bending at the end of the multinozzle and to allow for independent control of each nozzle. To better evaluate this technique, simulations were performed and compared with the experimental results. We observed a strong correlation between the simulated and experimental results. In addition, each nozzle in this multinozzle could be individually controlled.
