Furthermore,there are many process parameters that affect the printing accuracy and quality,among which each parameter is coupling and interacting.This paper proposed a method of controlling the accuracy and quality of printed patterns based on the regulation of the shape and size of the Taylor cone by varying the process parameters.A theoretical model was then derived and established that de- scribes the relationship between the line width printed with process parameters,printed material,and used substrate.Through the sys- tematic experimental study,the influences and rules of the printing process parameters on the Taylor cone and printed patterns were re- vealed:Furthermore,the ideal jet printing window for the same nozzle was optimized.Finally,the feasibility and validity of the experi- mental results were demonstrated by the typical engineering cases,and a pattern of minimum line width of 3 um was achieved with the nozzle diameter of 60 um.The proposed method and experimental results provide a basis for further improving the accuracy,quality, 收稿日期：201705-31 基金项目：国家自然科学基金资助项目(51775288,51375250)：青岛市创新领军人才资助项目(13-CX一18)工程科学学报，第 40 卷，第 3 期: 373--380，2018 年 3 月 Chinese Journal of Engineering，Vol． 40，No． 3: 373--380，March 2018 DOI: 10． 13374 /j． issn2095--9389． 2018． 03． 014; http: / /journals． ustb． edu． cn 电流体动力喷射 3D 打印工艺参数对泰勒锥和打印图 形的影响和规律 邹淑亭，兰红波，钱 垒，赵佳伟，周贺飞，朱晓阳，张广明，彭子龙 青岛理工大学青岛市 3D 打印工程研究中心，青岛 266520 通信作者，E-mail: hblan99@ 126． com 摘 要 电流体动力喷射 3D 打印是一种新型微纳增材制造技术，它具有成本低、结构简单、精度高、打印材料广泛等突出特 点和优势． 但是，由于电流体动力喷射 3D 打印的打印速度快、喷嘴和基底打印距离小，特别是对于微尺度特征图形的打印，其 实际图形及打印质量难以直接观测，而且影响打印图形精度和质量的工艺参数较多，各个工艺参数相互耦合和相应作用． 因 而直接有效的控制打印图形的精度( 线宽) 和质量( 线边缘粗糙度) 是其面临的一个挑战性难题． 本文提出一种通过调整打印 工艺参数间接控制泰勒锥形状和尺寸，进而实现对于打印图形精度和质量有效控制的新方法． 建立了线宽与工艺参数、材料 性能和基底关系的理论模型; 通过实验，系统研究并揭示了电流体动力喷射 3D 打印工艺参数对泰勒锥和打印图形的影响及 其规律; 优化出针对同一喷嘴较为理想的喷印工艺窗口; 并通过典型实验工程案例研究，采用内径 60 μm 喷嘴实现了最小线宽 3 μm 打印，验证了实验研究结果的正确性和有效性． 本文提出的方法和实验研究结果为电流体动力喷射 3D 打印的打印精 度、图形质量和打印稳定性改进及提高奠定了基础，并为简化和易于操作提供了一种切实可行的方法． 关键词 电流体动力喷射 3D 打印; 泰勒锥; 锥射流; 微纳增材制造; 工艺优化 分类号 TH164 收稿日期: 2017--05--31 基金项目: 国家自然科学基金资助项目( 51775288，51375250) ; 青岛市创新领军人才资助项目( 13--CX--18) Effects and rules of E-jet 3D printing process parameters on Taylor cone and printed patterns ZOU Shu-ting，LAN Hong-bo ，QIAN Lei，ZHAO Jia-wei，ZHOU He-fei，ZHU Xiao-yang，ZHANG Guang-ming，PENG Zi-long Qingdao Engineering Ｒesearch Center for 3D Printing，Qingdao University of Technology，Qingdao 266520，China Corresponding author，E-mail: hblan99@ 126． com ABSTＲACT Electrohydrodynamic jet 3D printing is an emerging and promising technology of micro- and nano-scale additive manu￾facturing with a low cost and high resolution，as well as a wide range of printed materials． However，due to the high printing speed and small standoff height between the nozzle and the substrate，it is especially difficult to directly observe and measure the printed patterns． Furthermore，there are many process parameters that affect the printing accuracy and quality，among which each parameter is coupling and interacting． This paper proposed a method of controlling the accuracy and quality of printed patterns based on the regulation of the shape and size of the Taylor cone by varying the process parameters． A theoretical model was then derived and established that de￾scribes the relationship between the line width printed with process parameters，printed material，and used substrate． Through the sys￾tematic experimental study，the influences and rules of the printing process parameters on the Taylor cone and printed patterns were re￾vealed; Furthermore，the ideal jet printing window for the same nozzle was optimized． Finally，the feasibility and validity of the experi￾mental results were demonstrated by the typical engineering cases，and a pattern of minimum line width of 3 μm was achieved with the nozzle diameter of 60 μm． The proposed method and experimental results provide a basis for further improving the accuracy，quality
