PhD Topic:

"Investigating the airflow instability in inkjet printer to understand the tiger striping print defect"

Research interests: CFD, microfluidics, inkjet systems, flow stability and external aerodynamics


The use of inkjet printers has been expanded to manufacturing electronics, solar panels, rapid prototypes, and reinforced composites. The expansion of the inkjet technology to other applications is yet limited by the restrictive print gaps (distance between media and printer head) that inkjet printers need to operate. Small print gaps prevent the printer from accommodating medias with variable thickness and increase the likelihood of the media striking the printer head and damaging the nozzles. At large print gaps, however, the print quality is likely to be compromised due to the misplacement of droplets that creates a printing defect commonly referred to as tiger-stripe. The goal of this project is to define, with the aid of CFD simulations and experiments, the airflow regimes where the tiger-striping problem occurs and characterize the flow features while relating them to the severity of problem.
