下照式光聚合固化技術,需要提高列印的速度,才能夠更廣泛的應用在批量生產,而高速列印技術目前基於DLP形式的較為容易實現,並且以Carbon3D的技術產生死區的方式為主,藉由死區降低其分離力,並提高列印速度。本實驗室提出使用抑制薄膜的技術,也可以產生死區提升列印速度。先前研究多為探討其功能性,尚未考慮到後續量產階段的需求,本研究目的為提升製備抑制薄膜的速度,以及改善薄膜本身的透光度、平整度,並探討薄膜列印壽命。
本研究透過使用濕膜塗佈機,改變原本直接倒入壓克力槽底製備的型式,且藉由使用一面矽壓感膠、一面壓克力壓感膠的雙面背膠PET薄膜,在不使用稀釋劑的情況下,將抑制薄膜的製程由48小時縮短為1小時,能快速地製造平整的抑制薄膜,並貼在壓克力板上。也探討了不同厚度抑制薄膜,其透光度與死區的差異,並針對抑制薄膜的使用壽命做探討,發現薄膜損壞的原因為抽吸力與熱的交互作用,同時提出增加列印壽命的方法,如增加抑制薄膜厚度、增加抬升高度、改變樹脂槽底板形式,結果顯示能有效的提升列印壽命。
Bottom-up mask projection stereolithography technique needs to increase the printing speed in order to be more widely used in mass production. Carbon 3D developed CLIP technology generates dead zones to reduces separation force and increases the printing speed. Our laboratory proposes of inhibition films technology, can also generate dead zone. Previous studies have mostly explored its functionality, and have not yet considered the needs of mass production. The purpose of this study is to increase the speed of preparing the inhibition films, improve the transmittance and flatness of the films, also discuss the printing life.
In this study, using wet film coater to change the original type prepared by pouring directly into the tank, and using a double-sided adhesive PET films with one side of silicon adhesive and the other side of acrylic adhesive, Without the use of thinner, the process of suppressing the film can be shortened from 48 hours to 1 hour, and a flat inhibition film can be quickly manufactured and attached to the acrylic plate. The difference in light transmittance and dead zone of different thickness films was also discussed, and the service life of the inhibition films as discussed. It was found that the cause of film damage was the interaction of suction and heat.Methods such as increasing the thickness of the inhibition film, increasing the lifting height, and changing the form of the resin tank bottom plate, the results show that the printing life can be effectively improved.
