摘要

在軟性顯示器或半導體製程領域的應用潛能很大。噴墨頭是噴墨技術中重要的關鍵零主件，如何設計出符合噴墨要求的噴墨頭成為成敗的重要關鍵。本研究是結合流體動力分析軟體FLOW-3D與微分演化演算法建構一套噴墨頭形狀最佳化的設計程式。在研究中針對噴墨頭外型及尺寸對噴射液滴之影響來改變設計，目標是利用形狀最佳化程式使噴射液滴增加集中性，減少衛星液滴的濺射，讓液滴噴射速度達到最快，噴射液滴體積達到最小，尋找到壓電式噴墨頭的最佳形狀設計。由研究結果顯示利用FLOW-3D與微分演化演算法所建構的外型最佳化設計程式，能依設計需求找到噴墨頭的最佳形狀。

Inject printing has high potential in the applications of flexible display and semiconductor manufacturing. The micro-droplet nozzle is key component of inject printing. The design of micro-droplet nozzle becomes the key for success of inject printing fitting application requirements. The fluid dynamic program FLOW-3D was integrated with differential evolution algorithm to construct a program for shape optimization of piezoelectric micro-droplet nozzle in this thesis. The shape and dimension of nozzle are used as design variables to encounter the different effects on the droplet. The objective of this study is to find out the optimum shape of nozzle including the effects of centralization、velocity、volume and satellite droplet. It is shown from the results of this study that the developed can find the optimum shape of nozzle for droplet requirement constraints
