Abstract
A printing method includes controlling timing parameters for application of electrical pulses to a piezoelectric nozzle of an inkjet printing head so as to dispense droplets of a material from the nozzle. The timing parameters are controlled to introduce gas bubbles into the droplets of material so as to reduce the density of the material to a selected density value that is less than a natural density of the material.
