A novel operation mode for piezo inkjet printheads has been invented to close the gap of current commercial printheads in meeting the requirements for advanced additive manufacturing. Subsequently, a printhead using the new technology has been developed along with the necessary sub-systems for integration in a printer. The new inkjet technology brings a combination of advantages, the most relevant being the capability to jet extremely high viscosity fluids, combined with very high productivity per nozzle, very wide drop size control and the capability to jet fluids with high particle load and large particle sizes.
