積層製造(Additive Manufacturing, AM)為一種新型加工型態，其概念為增材製造，能做出傳統減法加工所不能達成之設計與外型，但目前積層製造加工技術不能達成工業化之原因主要為加工速度慢與生產數量低兩缺點。
本實驗室致力於將光固化LCD製程技術往工業化發展，製作出全台灣第一台32″LCD光固化列印機，大幅提升光固化列印產量；本研究將致力於製作與分析大面積LCD光固化之背光模組，為達高光強度、高光均勻性與高光準直性等光固化列印需求，本實驗將不使用常見之陣列式透鏡模組，改用光學膜片式背光模組，經過多種搭配選用，大幅提升光均勻度與光準直性，並且比較各種光型所造成之列印影響，如軸向精度、物件銳利度與表面平整性。
且基於本實驗室開發之手機光固化列印系統之概念，並考量面板產業miniLED、microLED皆使用藍光燈源，為能順利與市場一同並進，將背光燈源由弱紫外405nm更改為可見光藍光460nm~470nm波長，且首次使用區域控光(local dimming)技術，大幅提升LCD對比度與LCD面板壽命。
本研究結果發現，光學膜片式模組非常適用於任何尺寸之光固化3D列印機，能提供一致性均勻化光源，並能將最小列印尺寸控制在大部分面板之Pixel size內，且搭配區域控光列印後，完全能抑制未預期固化殘渣、提升樹脂回收使用率、節省能源並大幅提升列印完整性。

Additive Manufacturing (AM) is a new type of processing. It can make designs and appearances that cannot be achieved by traditional subtractive processing. However, the main reason why the current additive manufacturing processing technology cannot achieve industrialization is there are two disadvantages: slow processing speed and low production quantity.
Our laboratory is committed to industrializing the light-curing LCD process technology, and produced the first 32" LCD light-curing printer in Taiwan, which greatly increases the output of light-curing printing; this research will focus on the production and analysis of large-area LCD light-curing backlight modules to achieve high light intensity, high light uniformity, and high light collimation. For printing requirements, this experiment will not use common lens array modules, instead use optical film backlight modules. After a variety of film matching options, the light uniformity and light collimation are greatly improved; and various light types are compared its printing influence, such as axial accuracy, object sharpness and surface smoothness.
And based on the concept of the mobile phone light curing printing system developed by our laboratory, and considering that the panel industry miniLED and microLED all use blue light sources, in order to smoothly advance with the market, the backlight source is changed from weak ultraviolet 405nm to visible light blue 460nm ~470nm wavelength, and the first use of local dimming technology, greatly improving LCD contrast and LCD panel life.
The results of this study found that the optical film module is very suitable for light-curing 3D printers of any size. It can provide a uniform light source, and can control the minimum print size within the pixel size of most panels. With local dimming technology printing, it can completely suppress unexpected curing residues, increase resin recycling, save energy, and greatly improve printing integrity.
