Abstract
We have developed the latest inkjet head corresponding to 3D modeling printer. This head is positioned as successor head of GEN3 series head. It has inherited the applicability, high durability and high reliability to a wide range of ink. And, it was to improve the productivity and high-density nozzle. Furthermore, it has heater in the head. This made it possible to eject liquid droplets a high viscosity ink. In addition to this feature, we adopted a rigid structure to chamber of head. This improved droplet discharge rate per time, and realized variable drop size control by jetting successive droplets in very short time.
