燈源裝置 以傾斜照射使光源強度不足、 整平裝置 調整方式過於複雜、
並且需要 新增自動剪切機構 改善過去人工剪線材之問題 。 各機構 在列
印前尚未有完整的 校 正方式 和列印參數 。
將
印頭模固定鎖點為 45 避免拆 裝時產生誤差、 改良 UV光源裝
置 為直照式 、設計含有荷重元以及僅有 Z軸調整的 整平裝置 、新增自
動剪切機構 改善過去人工剪線材之問題以及 制定列印模組以及列印
平台之校正標準。 透過熱重量分析儀 ( Thermogravimetric analysis, TGA )量測得知連續碳纖維材料之碳纖維含量為 60.5vol%。 透過光學
顯微鏡 ( Optical Microscope, OM )觀測列印後之疊層斷面以及尺寸，
得到最好之列印參數：列印間距 1.4 mm、層厚 0.8 mm、錨固 時間 5秒與列印速度 150mm/min。 本研究使用熱差式掃描分析 ( Differential scanning calorimetry, DSC )自行開發的光固化基材 固化溫度為 200 ℃

In recent years, the demand for carbon fiber composite materials has been increasing year by year, and 3D printing fiber composite material technology has gradually developed. In the past, our laboratory has developed 3D printing continuous carbon fiber composite material modules by itself, but the modules encountered many difficulties in printing: The fixed angle of the print head is relatively inaccurate, the light source device is tilted to illuminate the light source, the light source intensity is insufficient, the adjustment method of the leveling device is too complicated, and an automatic cutting mechanism needs to be added to improve the problem of manual wire cutting in the past. Each organization does not have a complete calibration method and printing parameters before printing.
The fixed locking point of the print head die is 45° to avoid errors during disassembly and assembly, the UV light source device is improved to be direct-illuminated, the design contains a load cell and a leveling device with only Z-axis adjustment, and an automatic cutting mechanism is added to improve the past labor The problem of cutting the wire and formulating the calibration standard of the printing module and printing platform. The carbon fiber content of the continuous carbon fiber material is 60.5vol% measured by thermogravimetric analysis (TGA). Observe the laminated section and size after printing through an optical microscope (OM) to get the best printing parameters: printing pitch 1.4 mm, layer thickness 0.8 mm, anchoring time 5 seconds, and printing speed 150 mm / min. In this study, we used differential scanning calorimetry (DSC) to develop a self-developed photo-curable substrate with a curing temperature of 200 ℃℃, which was used to formulate post-processing methods, and successfully printed flat plates, arc shells and hollow round tubes. .
