PIV Measurements of Airflow and Ink Mist Motion around Ink Jet Nozzles
Abstract:Dispersed ink mist occurs around ink jet nozzles and contaminates the inside of a thermal ink jet printer. It is required to clarify the fine droplet motion in order to prevent the contamination effectively. First, ink mist was visualized and airflow around ink jet nozzles was measured by Particle Image Velocimetry (PIV), when an ink jet carriage was scanned. Dispersed ink mist was observed at an upstream side of nozzles in scan direction, and it was confirmed that ink mist was blown up by the airflow. In addition, it was clarified that the airflow between a carriage and a paper varied depending on the carriage speed. Secondly, fundamental characteristics of ink droplets in the vicinity of ink jet nozzles were measured. The results reveal that PIV measurement is effective to gain an understanding of ink jet performance. Finally, airflow around ink jet nozzles was calculated numerically by Computational Fluid Dynamics (CFD). The results agree qualitatively with the experiments. Valuable design information to reduce mist contamination was obtained by the investigation.

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.
