FINE-Printhead for Sub-picoliter Droplet

摘要

The inkjet printer has become very popular these days. Most of the printers used in homes and offices are capable of producing photo quality printouts. The droplet volume of these printers lies in the range of 1 to 5 picoliter. Although the inkjet technology has the ability to produce even smaller droplet, sub-picoliter droplet, the requirement for the stable ejection and the system design to meet those requirements was not studied in detail. The object of this study is to clarify the configuration requirements of the stable ejection of the fine sub-picoliter droplets and realize those requirements by building prototypes.
