下照式光聚合技術流程中，分離力的問題一直是直深入探討的問題，因為這個問題大幅度影響了DLP列印技術之印速度以及限制了列印物件尺寸及特徵的設計。直至2015年CLIP技術的問世，此問題才出現了重大性的突破，「Dead zone」概念的出現為也為光固化高速列印建立了重要的里程碑。
本研究以抑制原理作為出發點，提出一物理結合化學之解決方案，實驗上將建立一可進行物理透析之環境，以去離子水(DI Water)作為透析液之基底進行測試，並加以進行材料調配改質，後續再將調配好之透析液中加入維他命C(Vitamin C)作為抑制劑，使產生化學抑制作用，來解決分離力之產生。
研究分析結果顯示，透析液藉由透析作用有效對於樹脂產生影響，並獲得相較於鐵氟龍膜更低之分離力結果。希望後續研究能使本研究更加完善，並為下照式光聚合技術分離力問題提供一新的優化方案。

In the buttom-up-type photopolymerization process, the problem of separation force has been a direct and in-depth discussion because it greatly affects the printing speed of DLP printing technology and limits the design of the size and features of printed objects. Until the advent of CLIP in 2015, a major breakthrough occurred. The emergence of the "Dead Zone" concept has also established an important milestone for high-speed printing of photocuring.
In this study, the inhibitory effect is taken as a starting point, and a physical and chemical solution was proposed. An experimental environment for physical dialysis was established, and DI Water will be used as the base of the dialysate for testing. The addition of Vitamin C in the dialysate produces a chemical inhibition to resolve the separation force.
The results of the study showed that the dialysate can effectively affect the photopolymerization of the resin and result in a lower separation force result than the Teflon film. It is hoped that the follow-up research will further improve this research and provide a new optimization scheme for the buttom-up-type photopolymerization technology.
