現今快速原型技術(Rapid Prototyping, RP)已在製造業得到了廣泛的應用，由於RP系統簡單、省時、成本低的優點，有效縮短開發週期進而提高市場競爭力。然而，RP 成型物件之強度的缺陷成為工業應用上的阻礙。本研究針對快速原型系統所使用的材料物性做改善，利用Halloysite 具有高的比表面積、高剛性、化學穩定性等，添加在光硬化樹脂中，並使用 3-氨基丙基三乙氧基矽烷表面處理來增加與光硬化樹脂的界面結合性。在此研究中，我們探討添加Halloysite 以及矽烷處理之 Halloysite 奈米複合材料的各項性能。矽烷處理之Halloysite 使用 X-ray繞射光譜、熱重量分析儀以及核磁共振光譜儀鑑定。奈米複合材料的機械性質及熱性質測定使用萬能試驗拉伸機、硬度計、熱重量分析儀及熱示差掃描卡計。並以掃描式電子顯微鏡對表面形態、分散性以及對光硬化樹脂的界面接合性做探討。Halloysite 奈米複合材料分析結果顯示：材料之拉伸強度隨著增加 Halloysite 含量增加而逐漸下降，而添加矽烷處理 Halloysite 之奈米複合材料，在 2phr 時性質為最佳；添加 Halloysite 之奈米複合材料硬度有提升，在添加矽烷處理之 Halloysite奈米複合材料上更為明顯；此外，材料拉伸斷裂面可以明顯觀察到矽烷界面的接合以及添加含量增加時分散性不佳的結果。

Nowadays, RP technology has gained great interest in manufacturing applications due to its advantages such as simplicity, low cost production, short manufacturing cycle time and increasing competitiveness. However, the physical properties of material is main problem for RP and become an obstacle to the application on industrial.
In this research, we investigate the effect of the addition of HNT in mechanical properties. Halloysite nanotube (HNT) has high specific surface area, chemical stability and other characteristics. The specimens were fabricated using photopolymer as matrix materials and HNT as reinforce materials. The surface adhesion was improved by using silane treatment. We proposed the addition of HNT as reinforcement in polymer matrix composites and improved the properties produced by RP. As the result, compared with neat photopolymer, tensile strength is decreased because the HNT had poor interfacial adhesion. Silane treatment of HNT using 3-Aminopropyl triethoxysilane has succeeded to improved tensile strength of lower phr.
