本研究為結合光聚合反應（photopolymerization）以及精密電鑄（Precision Electroforming）之新型微金屬積層製造系統，利用投影機投射之UV光固化光固化樹脂（Stereolithography Resin）作為動態光罩，遮蔽待鑄區域以外金屬，而後進行精密電鑄製程，使未被樹脂遮蔽之金屬基材處以電化學反應沉積金屬，當金屬沉積厚度與固化樹脂厚度相同時，該層金屬則列印完成，將金屬逐層堆疊，直到金屬沉積完成後，即完成微金屬3D列印。
　　本研究重點為探討待鑄物之形狀及其參數對金屬沉積成果之影響與關係，實驗之架構透過機台軟體校正得到更好的樹脂成形精度。並且以不同的電流密度及外形等參數進行精密電鑄時，觀測其電流效率、沉積金屬厚度、表面性質與邊角成形狀況，最後進行分析並找出此製程中不同形狀與不同參數間相互關係。
　　此研究成功的改善微金屬進行精密電鑄時所遇到的問題，並且更穩定的使用在微金屬之3D列印製程以及微機電製程中，其成果可望在未來與產業結合，為產業創造更有價值之製程。

　　Purpose of this study is novel micro scale metal additive manufacturing system that combines photopolymerization and precision electroforming. The projector uses a UV light to cure Stereolithography Resin as a dynamic mask to shield the area to be electroformed. Then, a precision electroforming process is performed to stack metal by electrochemical reaction of the metal substrate not covered by the resin. When the metal deposition thickness is the same as the thickness of the cured resin, the layer of metal is printed. The metal is stacked layer by layer until the metal deposition is completed, then, the micro scale metal 3D printing is completed.
　　In this study, we will focus on the influence and relationship in different shape of the thing under electroforming and forming parameters of metal stack results. The experimental structure is corrected by the software to obtain better resin forming accuracy. Observe the current efficiency, thickness of deposited metal, surface properties and corner forming conditions when precision electroforming is performed with different current density and shape parameters. Finally, an analysis is performed to find out the relationship between different shapes and different parameters in the process.
　　This research has successfully improved the problems which encountered in precision electroforming of micro-metals and it has been used more stably in the 3D printing process of micro-metals and micro-electromechanical processes. The results are expected to be combined with industry in the future to create more valuable process.
