快速原型(Rapid prototyping)技術為現在產業界熱門的生產技術，其優點為電腦控制全自動化、生產過程快速便利及能大幅度降低成本，但製作出來的物件強度差，不能應用在高強度的工件加工，故本研究針對快速原型系統所使用的材料物性做改善，利用奈米無機黏土使聚合物具有更高的強度、模量、耐熱性、尺寸穩定性及阻隔性，添加到光硬化樹脂中，提升其性能。此研究選擇凹土棒土、蒙脫土及人工合成鋰皂石分別以不同比例添加到光硬化樹脂中，探討無機黏土(clays)/光硬化樹脂奈米複合材料各項性能，並進行一系列檢測與討論。由傅立葉紅外線光譜儀(FT-IR) 及X-ray繞射分析儀探討Clays於光硬化樹脂基材中官能基與結構之變化。熱性質部分以熱重量損失分析儀(TGA)、熱示差掃描卡計(DSC)及動態機械黏彈分析儀(DMA)分別探討熱裂解溫度(Td)、玻璃轉移溫度(Tg)及動態玻璃轉移溫度(Tgd)，結果發現添加Clays的光硬化樹脂的熱裂解溫度皆有提升。機械性質部分則使用萬能試驗拉伸機及硬度計進行分析，結果顯示添加Clays的光硬化樹脂的拉伸強度與硬度皆有提升，且蒙脫土(MMT)/光硬化樹脂拉伸強度與硬度分別提升74.4%及8.4%。最後由掃描式電子顯微鏡(SEM)進行Clays/光硬化樹脂拉伸斷裂面分析，結果發現隨著Clays添加量增加使Clays/光硬化樹脂奈米複合材料的拉伸斷裂面其作用力痕跡越皺褶。

Rapid Prototyping (RP) can produce objects within a short time without the technical requirements, the process is fully automated, and there is no large amount of scrap. But the physical properties of material are the main problem for RP and become an obstacle to the application.
In this research, the physical properties of the materials utilized in the rapid prototyping system are improved. The nano-clay makes the polymer have higher strength, modulus, heat resistance, dimensional stability and barrier properties. The effects of attapulgite nanocomposites, montmorillonite nanocomposites and laponite nanocomposite materials are discussed.
The results showed that thermal properties are slightly improved. The tensile strength of attapulgite and montmorillonite increased with the increase of the content. The hardness of nanocomposites with attapulgite, montmorillonite and laponite increased. In addition, the tensile cross-section can see that the increase in the stress traces and more wrinkled.
