快速原型系統是以層層堆疊的方式製作出模型，此製造方式，不只可以有效地降低產品的開發時間與成本，也可以製作形狀複雜的產品，但也因為材料的機械性質與熱性質較低，因此也成為應用上的阻礙。在本次研究中，由於銅粉有較高的拉神強度與熱傳導性，因此其主要目的為使用光硬化樹酯/銅粉複合材料提升材料之機械性質和熱性質，使快速原型在工業應用上更為廣泛。此研究中所使用基材為PUA/HDDA光硬化樹脂，添加銅粉來提升機械性質與熱性質。 在實驗中，利用FTIR確定光硬化樹脂照光後硬化後是否完全反應，拉伸試驗機與Shore D標準硬度計測試機械性質，TGA與熱傳導機器測試熱性質。在研究結果中，機械性質中得到最大拉伸強度為32.56Mpa，增加了45%，熱性質中最大裂解溫度為410.41℃，增加了7%，最大熱傳導率為0.393(J/(m•K))，增加了65%。

Rapid prototyping (RP) system is the technology that fabricates model layer by layer. The technology not only can effectively reduce the development time and cost of product, but also can produce complicated product. However, the material of mechanical properties and thermal properties is poor, and become an obstacle to the application. So, in this research, the characteristic of copper powder have strong strength and high thermal properties, with adding copper to improve the material mechanical properties and thermal properties is become the propose in this research, and have wider range of rapid prototyping in the industrial applications. Test specimens were fabricated using polyurethane acrylate (PUA) and 1,6 hexanediol diacrylate (HDDA) photopolymer as matrix materials and copper powder as reinforce materials. Experiment was characterized by using FTIR to see the reaction before and after photopolymer curing, mechanical properties tested by tensile test and Shore D hardness tester, thermal properties tested by TGA and Hot Disk Thermal Constants Analyzer. As the result, in the mechanical properties the maximum of tensile strength is 32.56Mpa, improved up 45%, thermal properties of maximum degradation temperature is 410.41℃, improved up 7%, the maximum of thermal conductivity is 0.393(J/(m•K)), increased 65%.
