近年來因為積層製造技術的種種優勢，如縮短產品研發週期、高品質、客製化、低成本、低庫存量等。研究單位對於直接製造各種應用的物件及結構有很大的研究興趣，但因加工材料受限導致了應用範圍的侷限，這問題降低了積層製造本身的附加價值，阻礙其發展。
本研究主要是利用順向奈米碳管(Aligned Carbon Nanotube)，混成丙烯酸脂基材製成光固化樹脂/奈米碳管複合材料，當導電填充物添加量達到複合導電材料的滲透閾值時，導電率會急劇提升並達到電性穩定，最後成功製備出導電性高分子奈米複合材料，並利用光固化列印機製作出3D複雜結構。
為改善碳管的分散性，以自行設計之高分子型分散劑(SMA-amide)分散奈米碳管，分散劑以親油端的苯環和奈米碳管上的芳香族產生物理吸附及孤對電子對的相互作用，並藉由在奈米碳管周圍纏繞分子產生空間位阻，幫助穩定及分散溶劑中的碳管，並找出最佳分散劑種類及參數，提升奈米材料之分散性，隨後將分散劑、奈米碳管及光固化樹脂混合，製成光固化樹脂/奈米碳管奈米複合材料，探討了奈米碳管之添加量及列印參數，獲得最佳的導電性及成品質量。
最後成功的製備出感測人體碰觸的人機接口設備(HID)，複合導電材料本身具備導電性且能穩定感測觸碰訊號。搭配積層製造技術的種種優勢，在低成本的3D列印機上，生產者發揮創意自行設計感測元件的結構、樣式，甚至在未來生產各式傳感器且無須複雜的電路及生產設備，於眾多領域提供應用及發展。

In recent years, due to various advantages of Additive Manufacturing technology, such as shortening product development cycle, high quality, low cost, customization, and low inventory. 3D printing has gained significant research interest recently for directly manufacturing 3D components and structures for use in a variety of applications, but the limitation of the application range due to the limitation of processing materials, which reduces the added value of the laminated manufacturing itself and hinders its development.
This study mainly uses Aligned Carbon Nanotube material to form a photocurable resin/carbon nanotube composite material. When the amount of conductive filler added reaches the penetration threshold of the composite conductive material, the conductivity is sharply improved and electrically stable. Finally, the conductive polymer nanocomposite is successfully prepared, and the 3D complex structure is made by the photocuring printing mechanism. In order to improve the dispersibility of the carbon nanotube, the self-designed polymeric dispersant (SMA-amide) to enhance the dispersion of nanomaterials. The interaction of π bonds and lone pairs helps to stabilize and disperse carbon nanotubes in the solvent by winding molecules around the carbon nanotubes and creating steric hindrance. Find the best dispersant types and parameters, improve the dispersibility of nanomaterials, and then mix the dispersant, carbon nanotubes and photocurable resin to make photocurable resin/ carbon nanotube nanocomposite.
Finally, the composite materials were successfully used in capacitive Human-Interface-Devices (HID). In the future, this composite material can produce various high-tech technologies on low-cost photopolymerization curing printers. Sensors without the need for complex circuit and sensor production facilities, and provide applications and development in many areas.
