Abstract

Droplet jetting technology is widely used in 3D printing. In which process, the flow rate of material extrusion from the nozzle is one of the keys that affect the printing performance, such as the droplet size and its uniformity. In this paper, a model was developed to predict the jetting flow rate. First, by analyzing the dynamics of the power law fluid flowing in circular tube, a flow rate model of tube flow is obtained. Second, the dynamics of fluid flowing through a cone tube is obtained. Finally, a set of jetting flow rate model is developed by combining the results delivered in previous two steps. The model’s validity was verified by some numerical simulations, the results showed that the model developed in this paper can predict the jetting flow rate effectively.
