DOD Piezoelectric Inkjet application:
A drop-on-demand (DOD) inkjet printer only releases droplets when being triggered, either by thermal or piezoelectric effect piezo ceramics rings. In thermal DOD printing (Thermal Inkjet) a heating piezo element inside the print head induces the formation of a small vapor bubble; thereby, piezoceramic rings generated pressure forces the droplet out of the nozzle. In commercial applications the thermal DOD printing is often referred to as bubble jet printing. They include a limited ink variety, as thermally sensitive materials cannot be processed and a lower durability of the print heads. Piezo inkjet printers (Piezoelectric ceramics Inkjet) exploit the inverse piezoelectric effect, namely by alternating the voltage a piezoelectric membrane is deformed and squeezes the drop through the nozzle. DOD inkjet printers are mostly designed in multi-nozzle configuration,
