| dc.description.abstract | 本研究是以上照式光固化成型技術為基礎進行積層製造，主要架構是以 DLP 投影機作為光源，並在列印原料的光敏樹脂中摻入奈米碳管使其具備導電性，但在光敏樹脂中添加奈米碳管會使樹脂之黏稠度及不透明度增加，除流動性變差外，散步在光敏樹脂中的奈米碳管會阻擋光線穿透，導致使用上照式列印系統會遇到一定的困難。因此本研究開發出用於控制單層厚度的內缸機構，有效克服列印過程樹脂無法回填列印平台的問題，並成功印製出具備導電性之成品，同時探討列印樹脂之固化前後之電阻差異。
在能穩定印製出具導電性的成品後，便嘗試探討列印參數如切層厚度、列印層數，同時比較各參數下之成品電阻。最後發展出列印成品的應用性，將其作為應變計使用，同時設計出一套懸臂樑實驗架構用於檢驗本實驗之列印成品應用的可行性。 | zh_TW |
| dc.description.abstract | This study is based on top-down photo-curing additive manufacturing. The main framework utilizes a DLP projector as the light source, incorporating carbon nanotubes into the photosensitive resin used as printing material to impart conductivity. However, adding carbon nanotubes to the photosensitive resin increases its viscosity and opacity, leading to decreased flowability and the dispersion of carbon nanotubes in the resin obstructing light penetration. This creates certain difficulties when using a top-down 3D-printing system.
Therefore, this study developed an inner vat mechanism to control the single-layer thickness, successfully overcoming these challenges and producing conductive products. Additionally, the study examines the resistance differences in the resin before and after curing. After stabilizing the production of conductive products, the study explored various printing parameters such as layer thickness and the number of layers, comparing the resistance of products under different parameters. Finally, the application of the printed products was developed, using them as strain gauges, and designing a cantilever beam experiment framework to test the feasibility of applying the printed products in this experiment. | en |
