摘要：The melt electrowriting (MEW) has broad applications in regenerative medicine and micro-nano electronics. It is an efficient micro-nano scale additive manufacturing technology; however, the fiber jet lag effect of MEW limits the deposition precision and resolution of fiber shape. In this study, the principle of the jet lag effect is studied to overcome the defect of printed structure distortion and improve the ability to print complex structures. A mathematical model of trailing fiber trajectory is established. The study covers jet lag and liquid rope coiling analysis at different speeds. A strategy is adopted by introducing a buffer zone at the corner of the printing structure. The printing path is subdivided and optimized to suppress the influence of jet lag. The results show that the deposited fibers' corner radius is around 63.81 & PLUSMN;5.66 & mu;m, which is significantly smaller than that of unoptimized groups. Finally, by utilizing the improved printing paths, the high-precision and complex structures are printed, which demonstrates the feasibility of optimizing the buffer zone for the MEW.
