　　縮短產品開發週期和減少成本，成為現代製造業賴以生存的關鍵，快速將多樣化的產品推向市場求得市場先機，因此發展出快速模具技術。本研究運用快速模具技術製造菲涅爾透鏡之模具，係利用矽膠當作中介模具，再使用金屬樹脂製作熱壓印模具，但傳統快速模具為全金屬樹脂製造，價格甚高。故本研究為節省成本和提升表面形狀精度，以快速模具結合中介模具與背襯模板，提出混合快速模具技術。
　　由研究結果得知，運用快速模具技術製造菲涅爾透鏡熱壓印模具，其總轉寫率為97.12 %，熱壓印成品表面粗糙度比原型件高8.95 %。且結合背襯模板來開發混合快速模具降低成本78.77 %，表面之形狀精度改善77.77 %，熱壓印之殘留應力比射出成形低，表面自由能僅為29.1 mN/ m，極適合脫模。因此本研究所提出之混合快速模具之優點涵蓋製作方法簡單、低製作成本、低殘留應力、高表面形狀精度，以及優良尺寸精度。

　　The key to survival in the modern manufacturing industry is to shorten product development period and reduce cost in order to quickly push diversified products to the market and seize opportunities. As a result, the rapid tooling (RT) technology has been developed. In this study the RT technology has been utilized to make the mold of Fresnel lens, where the silicone is used as the intermediate mold, and the epoxy resin is used to make hot embossing mold. However, the traditional RT mold is made of epoxy resin with a rather high cost. Therefore, for cost saving and enhancement of geometry accuracy, in this study the hybrid mold technology has been proposed based on the integration of RT mold and backing material.
　　The results of this study have indicated a transcription rate of 97.12% of hot embossing mold of Fresnel lens made by RT technology, while the surface roughness of the hot embossing finished product is 8.95% higher than the prototype. The hybrid mold technology developed based on the integration with backing material has led to 78.77% of cost reduction and a 77.77% improvement on geometry accuracy. The residual stress of hot embossing is lower than injection molding, and the surface energy is only 29.1 mN/m, which is very suitable for stripping. Therefore, the hybrid mold technology proposed in this study has led to the advantages of simple fabrication method, low fabrication cost, low residual stress, high geometry accuracy and superior dimension accuracy.
