超疏滑薄膜雖然能解決現今之下照式光固化技術中，列印速度的提升總受限於列印層脫離樹脂槽底的拉應力問題，實現了光固化的連續列印，但此塗層的壽命會在實際列印中而有所損耗，其塗層的總壽命太短而不能有效地進入現有市場。本研究在此超疏滑薄膜的塗層列印下，加裝了超音波震盪子，利用超音波的震盪原理，找出最佳的超音波震盪子安裝位置、頻率對此塗層壽命的影響，最後在對列印樣本外觀、樹脂槽列印到極限之後的型態進行探討。
本研究最後發現，超音波震盪會使塗層中多孔性結構層中的全氟聚醚Perfluoropolyethers，PFPE）損耗降低，從而讓PFPE能更久的保護塗層，避免其受到破壞之外，也能協助破真空，使其達到提升超疏滑薄膜塗層壽命的效果。

Although the slippery film can solve the current bottom-up stereolithography
technology, the increase in printing speed is always limited by the tensile stress problem of
the printing layer leaving the bottom of the resin tank, and realizes the continuous printing
of Vat-polymerization, but the life of this surface will be lost in the actual printing, and the
total life of the coating is often too short to effectively enter the existing market. In this study,
under the coating printing of this ultraslipsible film, an ultrasonic oscillator is installed, and
the ultrasonic oscillator principle is used to find out the optimal installation position of the
ultrasonic oscillator and the influence of the frequency on the life of the coating, and finally
the appearance of the printed sample and the shape of the resin tank after printing to the limit
are discussed.
In this study, it was found that ultrasonic oscillation will reduce the loss of
perfluoropolyethers (PFPE) in the porous structural layer of the coating, so that PFPE can
protect the coating for a longer time, avoid damage, and also assist in breaking the vacuum,
so that it can achieve the effect of improving the life of the ultra-smooth film coating.
