中文摘要：

基于EHD微纳尺度3D打印技术（电喷印）是最具应用前景的微纳尺度3D打印技术之一。通过实验研究了电喷印过程中导电银浆体积浓度、喷印距离、喷印电压及喷印头移动速度对成线性能的影响。实验结果表明：外加电压在一定范围内能形成泰勒锥,过大或过小都会影响泰勒锥的形成;在此范围内存在最佳值2 000 V,使线宽最小。随着喷印头移动速度的变化,线宽变化显著,速度过小或过大分别导致线宽过大或无法成线的现象。导电银浆体积浓度过小会导致线宽过大、体积浓度过大导致粘度过大无法喷印;存在最佳值6：1使线宽最小。在一定的喷印距离0.05-0.1 mm的范围内变化时,可以形成稳定喷印。距离过大或过小会导致无法成线现象。

英文摘要：

E -jet printing （EHD） is one of the most important can realize high precision patterning of sub micron and miero/nano scale 3D nano scale resolution printing technology, which without nozzle clogging. The effect of conductive silver paste volume concentration, spray printing distance, jet printing voltage and the jet head moving speed on line performance are studied through experiments in this paper. Results showed that, applied voltage within a certain range can form the Taylor cone, too big or too small will influence the formation of Taylor cone ; within the scope of the voltage is the best value is 2 000 V, minimize the line width. As the change of jet head moving speed, line width change significantly, too small or too big resulting in the phenomenon of line width is too big or not into line. Conductive silver paste volume concentration is too small to lead to the big line width, the volume concentration is too large to printing can not realize ; the optimal value is 6 ： 1 minimize the line width. In a certain range of spray printing distance （0. 05 -0. 1 mm） , can form stable spray print. Distance is too big or too little to lead to cant into line phenomenon.
