一种可消除承印物影响的电流体动力喷墨打印技术

Electrohydrodynamic Jet Printing Capable of Removing Substrate Effects and Modulating Printing Characteristics

电流体动力喷墨打印技术(EHDP)已广泛应用于直接印刷。然而,现有的EHDP方法,其印刷特性受承印物的影响,且打印线宽由喷嘴的尺寸决定。本文提出的一种EHDP新方法能够消除承印物的影响,并且能够通过控制喷嘴阵列中每个喷嘴的开关来实现对打印线宽的控制。本文检验了EHDP系统的印刷特性,同时证明了喷嘴阵列开关控制的可行性。这种新型EHDP技术可以不受承印物的影响得到稳定的弯月形液面;即使使用同样的喷嘴也能得到不同的线宽。

Electrohydrodynamic jet printing （EHDP） technique is widely used for the direct writing. However, in the existing EHDP method, the printing characteristics are affected by the printing substrate used, and the printed line width is determined by the geometry of the nozzle. We propose an EHDP method which is capable of （1） removing the effect from the substrate, and （2） controlling the line width through the ON/OFF control of the each nozzle in the nozzle array. Printing characteristics of our EHDP system were examined and successful ON/OFF control of the nozzle array were demonstrated. By using the proposed EHDP, it is expected that stable meniscus regardless of the effect from substrate and different line widths even using the same nozzle can be achieved.
