目前3D列印連續碳纖維熱固型複合材料的應用尚未普及，因此本實驗室開發雙固型環氧樹脂搭配連續纖維進行列印的製程，並分為連續碳纖維線材製備系統與連續纖維列印模組，而在製備系統方面雖可製備線材但還無法連續製備成捲，並且製備過程中由於樹脂的高黏度很容易造成塑型孔的阻塞或使纖維斷裂，本研究主要以改善線材製備系統所遭遇的問題，讓樹脂和纖維有更好的結合並將線材製備成捲，最後透過列印整平模組列印線材並有良好的堆疊。
本研究透過加熱樹脂槽與塑形孔解決製備過程線材容易斷裂與塑形孔阻塞的問題，使用孔型刮板來改善人工塗佈樹脂的方式，除去線材多餘樹脂並回流於樹脂槽，讓線材可以製備成捲，搭配連續纖維線材列印模組與整平刮板模組，修整單根斷面形狀找出較好堆疊的列印參數，由實驗結果得到製備線材纖維比例由原本的52.49%上升到了 67.07%，孔隙率的部分從7.09%減至3.61%整體下降了49%，標準差也從2.05%減至1.10%，而在列印的部分，透過整平列印讓線材斷面有較平整的矩形，在單根線材尺寸寬度與厚度的標準差，比未整平的線材分別下降了60%與45%。

At present, the application of continuous carbon fiber thermosetting composite materials in 3D printing are not yet widely implemented. Therefore, our laboratory has developed a printing process that involves the combination of dual-cure epoxy resin and continuous fiber, which is divided into a continuous carbon fiber filament preparation system, and a continuous fiber 3D printing module. For the preparation system, although the filaments can be prepared, it cannot be continuously prepared into rolls. Moreover, the high viscosity of the resin can easily block the molding nozzle or even break fibers during the preparation process. This research mainly aims to improve the problems encountered by the filament preparation system, to support better combination of the resin and fiber, and then the preparation of filament into rolls, as well as leveling of the module filaments through 3D printing and ensure good stacking.
By heating the resin tank and the molding nozzle, the research solves the problem of easy breakage in filaments and blockage of the molding nozzle during the preparation process. A hole-shaped scraper is used to improve the manual application method of resin, removing excess resin from the filament and reflow it back into the resin tank, so that the filament can be prepared into rolls. With the continuous fiber filament printing module and the leveling scraper module, the single cross-section can be trimmed to find out the printing parameters for better stacking. According to the experimental results, the proportion of prepared filament fibers has increased from 55.58% to 69.33%, the porosity has been reduced from 7.46% to 3.87%, overall decrease is 48%, with standard deviation reduced from 2.03% to 1.09%. As for printing, a leveled rectangle is produced for the cross-section of the filament through flattening printing. The standard deviation for the width and thickness of a single filament is 60% and 45% lower than that of the unleveled filament, respectively.
