The design of inject printing system is the key for successful applications. In this study optimization of shape of piezoelectric micro-droplet nozzle in consideration of cycle setting of pressure source is investigated by integration of commercial program FLOW-3D with self-adaptive differential evolution (SADE) algorithm. The objective is to apply the optimization technique in designing the shape of nozzle and cycle of pressure source for obtaining the droplet fitting the desired properties such as centralization、 velocity、 volume、 short pressure cycle and no satellite droplet. From of results of this study, the developed program combining Flow-3D simulation and SADE optimization can find optimum shape of nozzle and pressure source cycle setting with desired droplet behavior under the constraints of design requirements.
