Abstract: The droplet dynamics in droplet-based printing and its relevance to additive manufacturing are studied using a finite volume/Volume-of-Fluid (VOF) method. The numerical results are reasonably compared with the experimental data from Kim and Chun [22] for a water and ink droplet shape evolution on the polycarbonate surface. A parametric study is conducted to study the shape and base diameter of the droplet during the printing process. It is found that the contact angle has a significant effect on the drop dynamics and resolution of the deposited droplet. The coalescence of two droplets is analyzed to simulate the continuous printing process, and the effect of traverse speed on the final resolution is also presented.
