A laminated, multi-substrate inkjet head that called “electrostatic inkjet head” has been designed, which consists of three parts: upper layer (Si), middle layer (Si), bottom layer (glass). Middle layer includes nozzles, ink cavity and diaphragms. Ink is jetted out of the ink cavity through the nozzle, and diaphragm defined as the bottom of ink cavity. Charging channels is used for supplying ink to...
The effects of electrohydrodynamical (EHD) drop-on-demand inkjet variables on the droplet diameter are presented in this paper. The EHD printer uses a high pulsed voltage to generate strong electric field in the vicinity of the apex of the dome-shaped liquid meniscus and thus micro-jetting ejection of droplet comes forth. And the liquid shaping processes are revealed through CCD. The droplets with...
