目前使用下照式DLP機台進行彈性體3D列印時,彈性體的高黏度與變形特性使得成型平台所需抬升距離較一般光敏樹脂還高,造成列印彈性體時所花費的時間比一般光敏樹脂還多,且溫度也影響彈性體的列印,因此,本研究的目的在於透過成型平台抬升速度、抬升距離、延遲曝光時間、樹脂種類進行列印比較,提出解決彈性體變形及溫度問題並提升列印速度與穩定性的列印策略。
本研究使用光聚合抑制薄膜進行彈性體列印時,彈性體的變形造成抬升距離的提高,影響列印的速度,此外彈性體還受到溫度的影響,導致過快的曝光間隔會造成溫度提高而導致列印失敗,因此本研究透過列印波形的型態分析與列印極限試驗,使用不同抬升速度、抬升距離、延遲曝光時間探討列印參數對變形與溫度之影響。本研究發現,加快抬升速度,提高抬升距離,並控制溫度,可解決彈性體溫度、回流及變形問題,並提升列印速度與穩定性。
At present, when using a bottom - up DLP 3D printing system to print elastomer, the high viscosity and deformation characteristics of the elastomer make the lifting distance of the platform higher than that of common resins, resulting in the time spent more than common resins, and temperature also affects the printing of elastomers. Therefore, the purpose of this research is to compare printing with the lifting speed of the platform, lifting distance of the platform, delayed exposure time, and resin type, and to propose a printing strategy that solves the elastic deformation and temperature problems and improves the printing speed and stability.
In this study, when the photopolymerization inhibitor film is used for elastomer printing, the deformation of the elastomer increases the lifting distance of the platform, which affects the printing speed. In addition, the elastomer is also affected by the temperature, resulting in an fast exposure will increase the temperature and causes the printing to fail. Therefore, the study uses different lifting speeds and distances of the platform and delayed exposure times to compare the influence of printing parameters on deformation and temperature through the analysis of the printing waveform and the printing limit test. Increasing the lifting speed and distance of the platform, and controlling the temperature can solve the problems of elastomer, and improve printing speed and stability.
