The e-Jet printing process involves a conductive nozzle, a substrate, and an electric field. A high voltage is applied between the nozzle and the substrate, causing the liquid at the nozzle tip to form a cone, known as a Taylor cone. This cone emits a fine jet of ink, which breaks into tiny droplets that are directed towards the substrate. The size of these droplets can be controlled by adjusting the electric field, ink properties, and nozzle size.
