本研究為一新型光固化3D列印系統之開發，本系統使用行動裝置(如智慧型手機、平板電腦)取代傳統光固化技術之光源及圖像產生器；使用具撓性之時規皮帶搭配剛性之滑軌，取代需精密定位之螺桿與光軸，顛覆傳統光固化3D列印系統之框架。
此外，本研究為行動裝置式光固化3D列印系統之重要參數”曝光時間”建立一套調教之標準流程。以傅立葉轉換紅外光譜(Fourier Transform Infrared Spectrometer, FTIR)分析，量化光固化樹脂之固化程度；當系統更換光源時，可利用該量化之樹脂固化程度對曝光時間進行調教。如此一來，即使將系統之光源做更換，亦能按部就班調整製程參數，令系統發揮原有之效能。
最後，本系統將列印成品與市售光固化機種MiiCraft做尺寸精度上之比較，做為系統效能之評估。結果顯示，本系統以智慧型手機之面板做為光源，搭配市售之光固化樹脂NT-01，能夠將XY方向之尺寸偏差控制在260μm以下。將樹脂添加抑制劑後，則可控制在180μm以下，已達到與市售之光固化3D列印系統MiiCraft相當之性能；Z軸方向之尺寸偏差在60μm以下，已優於市售之3D列印系統MiiCraft (大於300μm)。

This study is about a mobile device vat photopolymerization 3D printing system. The system uses a mobile device instead of an expensive laser or a UV lamp to be the light source and pattern generator. Using a timing belt and a linear slide instead of a screw and a shaft to drive the Z-axis stage. This system allows larger positioning tolerance and has high z-axis resolution at the same time by virtue of the flexibility of timing belt.
Besides, this study established a standard operating procedure for adjusting the important parameter in the 3D printing process, the “exposure time”. This procedure can quantify the curing degree of the resin by using the Fourier Transform Infrared Spectrometer (FTIR). The quantified curing degree can be used to readjust the exposure time of the 3D printing system when the light source is changed (e.g., the light source is changed from a smartphone to a tablet or another smartphone), let the 3D printing system can operate like the light source is never changed.
Finally, measuring the dimensional deviation of the mobile device 3D printing system by printing some samples. The result shows that the dimensional deviation of the X-Y axis is under 260μm by using commercial resin “NT-01” and is under 180μm by adding inhibitor into the resin “NT-01”. The Z-axis dimensional deviation is under 60μm no matter adding inhibitor or not.
