製作隱形牙套所使用的牙模需求越來越高，傳統使用SLA技術會造成樹脂浪費以及速度較慢的問題。而下照式DLP技術能同時改善這兩個問題，但是一般DLP機台受限於分離力問題因此設計的較小台導致不利於量產。本研究的目的為使用抑制薄膜的高速列印技術，利用創造死區的方式降低分離力，結合大面積的DLP機台提升產量，將其應用於牙模的量產，並對列印的成功率及速度進行探討。
本研究搭建了DLP型大面積高速3D列印機台，於抑制薄膜上進行不同參數的列印測試，透過對3個不同區段的受力曲線分析，將參數對曲線的影響找出。過程中發現其失敗原因為樹脂排不出造成槽底形變導致平台與槽底間距不正確所造成，透過提升間距的校正方式可以有效改善樹脂排不出的問題，再搭配多孔板的使用可以更快的排出堆積的樹脂，使成功率由80%提升至接近100%。另外本研究透過對受力曲線的分析，制定出參數的修改策略，透過4個步驟即可找到穩定且快速的列印參數，利用不同層數對應不同參數的方式，將24個牙模的列印時間減少50%。

The demand for dental molds used to make invisible braces is increasing. The traditional use of SLA technology will cause resin waste and slower speed. The down-illuminated DLP technology can improve these two problems at the same time, but the general DLP machine is limited by the separation force problem, so the small design of the machine is not conducive to mass production. The purpose of this research is to use the high-speed printing technology , reduce the separation force by creating a dead zone, and combine it with a large-area DLP machine to increase the output, apply it to the mass production of dental molds, and to improve the printing success Rate and speed are discussed.
In this study, a DLP type large-area high-speed 3D printer was built, and the printing test of different parameters use the high-speed printing technology. Through the analysis of the force curve of 3 different sections, the influence of the parameters on the curve was found. During the process, it was discovered that the reason for the failure was that the resin could not be discharged and the groove bottom deformed and the distance between the platform and the groove bottom was incorrect. The correction method of increasing the distance can effectively improve the problem of resin not being discharged, and the use of a perforated plate can be more Quickly discharge the accumulated resin, which increases the success rate from 80% to nearly 100%. In addition, this research has worked out a parameter modification strategy through the analysis of the force curve. Stable and fast printing parameters can be found in 4 steps. Different layers correspond to different parameters, and the rows of 24 dental molds Printing time is reduced by 50%.
