下照式光聚合技術因為分離力而限制了製造的速度，而基於DLP形式的技術以Carbon3D 的技術產生死區的方式為主，藉由死區降低其分離力，提升整體列印速度。本實驗室所提出使用抑制薄膜的技術，也可以產生死區提升列印速度。藉由死區可以進行主軸只有抬升的連續列印，除了能夠加快列印速度，也可以使用較低的切層厚度進行列印，得到光滑的表面。先前研究對於抑制膜還停留在高速列印，尚未對連續列印的部分進行探討，本研究目的為藉由抑制薄膜技術進行連續列印，並達到表面粗糙度的改善。
本研究先將抑制薄膜進行連續列印限制的測試，得知連續列印的面積限制，藉由受力分析得知連續列印參數對於曲線的影響，發現在穩定列印狀況下並不會有曲線變化。使用4 µm之層厚進行不同應用端的驗證，成功列印出具有-15°逆拔膜角設計之LED封裝透鏡，並在切層厚度4 µm的限制下，得到表面粗糙度為0.19 µm的隱形眼鏡，在使用相同切層厚度的情況下，連續列印與微上下列印的表面粗糙度相差3倍，最後藉由性質差異較大的樹脂成功列印出具有光滑表面的微針貼片。

The bottom-up photopolymerization technology have limitation in the manufacturing speed due to the separation force. In contrast, Carbon3D technology generate a dead zone, which reduces the separation force and increases the overall printing speed. This laboratory uses the suppression film to generate dead zones. The dead zone can be used to carry out continuous printing. On previous research, the high-speed printing only discusses about the inhibition film, and the continuous printing part has yet to be discussed. The purpose of this research is to carry out continuous printing by inhibiting thin film technology and to achieve the improvement of surface roughness.
The inhibition film was first tested to know the area limit of continuous printing. Furthermore, through force analysis, we know the influence of continuous printing parameters on the separation force curve. Using a 4 μm layer thickness, we successfully printed an LED package lens with an -15°undercut design and obtained a contact lens with a surface roughness of 0.19 μm. With the same slice thickness, the surface roughness of continuous printing is three times better than micro printing. Finally, a microneedle patch with a smooth surface was successfully printed using a resin with a large property difference.
