光固化列印系統目前仍在發展中，但大多數的光固化系統是使用DLP或者雷射作為光源，多數的多材料機為上照式，少有下照式的多色多材料3D列印系統，而本系統是使用行動裝置下照式3D列印系統，搭配可組裝數個材料槽的旋轉圓盤，便可達到多色以及多材料的成品。
本研究為改良多色光固化3D列印系統之研究，與原系統同樣是利用攜帶型裝置，搭配旋轉盤，而改良後使機台兼具列印多色以及列印多材料之功能，並且修正原先系統上所出現的問題。改良後旋轉盤的定位精度可提升50％以上，列印大物件時便不會直接撞上樹脂槽；而有關手機被轉盤拖動的問題，改良後會讓手機在轉盤要轉動前先遠離轉盤，當轉盤定位後再回歸至原先的位置，手機在列印中也不會被旋轉盤帶動，提高列印的成功率。

The DLP systems is still in development, but most of the systems use DLP or laser as the light source. Most multi-material machines are top-illuminated and there are few down-lit multi-color multi-material 3D printing. This multi-color multi-material 3D printing system used a mobile device, with a rotating disc that can be assembled with several material slots.
This study is to improve the multi-color light-curing 3D printing system and is the same as the original system, which uses a portable device and a rotating disk. The improved machine has the function of printing multi-color and printing Multi-materials, and corrects problems that occurred on the original system. The improved positioning accuracy of the rotating disc can be increased by more than 50%. When printing large objects, it will not directly hit the resin tank; and the problem that the Mobile phone is dragged by the turntable will also be sloved, the Mobile phone platform will keep away before the turntable turns away. When the dial is positioned and then returned to the original position, the mobile phone will not be driven by the rotating disc during printing, which improves the success rate of printing.
