- Here we demonstrate the generation of droplets that are much smaller than the nozzle they emerge from. By exploiting the violent collapse of a liquid cavity, we generate drops up to 80 times smaller than the nozzle. A combination of experiments, simulations and theory led to the developed of a model to predict the size of the droplets based on the fluid properties and driving pressure used to create and collapse the cavity. The technique can be used to print highly viscous fluids and fluids with high particulate concentrations for a variety of applications such as bioprinting or printed electronics.
