本論文將積層製造技術(Additive Manufacturing, AM)應用於製備壓電纖維的近場式靜電紡絲技術(Near-Field Electrospinning, NFES)，建構 3D 直寫式靜電紡絲積層製造設備，並以纖維之直徑調控作為技術原理，開發創新的金字塔式3D 結構堆疊方法。其中設備建構以可程式邏輯控制器(Programmable Logic Controller, PLC)作為控制核心，透過階梯圖程式、人機智能介面之開發與電路配置建構機電控制系統，控制 X、Y、Z 三軸平台執行連續路徑移動作為纖維收集機構，再搭配高壓電源供應器、注射泵浦及微孔針頭組成ㄧ靜電紡絲製程設備。製程開發的部分選用多分子聚合物聚偏氟乙烯(Polyvinylidene fluoride, PVDF)作為原料調配溶液，設計實驗逐次調整收集距離、電壓、收集速度等製程參數，將纖維收集結果以光學顯微鏡搭配工程量測軟體量測其直徑，分析出收集速度對纖維直徑具有決定性的影響。藉由收集平台路徑設計與纖維直徑的調控，開發金字塔式 3D 結構堆疊方法，並選用導電率良好的銅作為收集端，降低纖維因不穩定性而無法堆疊成 3D 結構的可能性。最後本論文以電子顯微鏡觀察纖維堆疊結果，證實纖維確實可藉由本論文技術堆疊出具有一定高度之3D 金字塔微型結構，未來可望應用於微奈米級 3D 結構之快速原型開發(Rapid Prototyping, RP)，拓展壓電式微機電系統(Microelectromechanical Systems, MEMS)的應用層面。

In this paper, we construct a direct-write near-field electrospinning equipment and propose a novel method to fabricate 3D nanoscale pyramid structure base on additive manufacturing (AM) process. For equipment construction, we apply high voltage power supply and injection pump system to produce fibers from polymer solutions and use programmable logic controller (PLC) to control the motion of three-axis linear stage, so the fibers can deposit on the substrate with different pattern. Also, an intelligent user-interface is built to monitor and manipulate the three-axis stage. For process development, we use polyvinylidene fluoride (PVDF) as the solutions. By adjusting different processing parameters we can measure different fiber diameter by the help of optical microscope (OM). Finally, we conclude that motion speed has the most influence on fiber diameter from the experiment results, so we fabricate 3D structures by adjusting the motion speed of each layer during the process and form a pyramid structure. The results show fibers stack on each other easier than stacking fibers layer-by-layer with the same diameter. This novel 3D printing scheme promises different fiber diameter in a same process, willing be applied to the development of 3D nanoscale objects.
