積層製造光固化技術中，成品精度佳為此製程之主要優勢，但若要增加成品的導磁、導電應用，樹酯在混入顆粒後，必定會影響光固化成型，造成精度喪失與製程上的問題。目前積層製造技術的導磁與導電性材料，皆是把石墨烯與導磁粉末混入高分子線材後，利用熔融沉積成型的技術，加熱線材擠出成型。本研究使用四氧化三鐵粉末，混入生醫光聚合樹酯，並整理成型參數，做為未來導磁性的光聚合生醫材料的成型依據與生醫應用。
本研究利用DLP動態式光罩系統，在不改變生物及化學性質下，以物理快速攪拌方式，搭配兩種不同材料性質的生醫樹酯材料黏度，使奈米氧化鐵粉混入兩種材料系統成型，探討最大氧化鐵粉末濃度、光啟始劑比例與氧化鐵粉末濃度相互影響的列印時間關係，尋找較佳的列印參數。統整製程參數後，量測各個混入不同氧化鐵粉濃度試片之磁場大小，最後利用已使用於組織工程的可降解性生醫材料，列印出具有磁性的三維磁性結構。研究結果得到，在成型性方面，以較低的四氧化三鐵粉末濃度，搭配3%的光啟始劑，擁有較佳的精度；在考量磁場大小方面，若較無微小孔洞精度偏差的考量，可使用較高濃度的四氧化三鐵，達到更好的導磁應用。

Photo-curing process has the best accuracy in additive manufacturing. In order to make the workpieces have the applications on conduct electricity and magnet permeability, the particles mixed with resin must cause the accuracy and forming problem. Recently, many researches shows that they have mixed graphene and magnetic powder in polymers, using Fused-Deposition Modeling process to heat the materials and form the workpieces, achieving the requirements of conduct electricity and magnetic permeability. This research mix ferrite oxide powder in bio-resin, investigating the forming parameters and make the photo-curing biomaterials refer in the future.
Considering the biochemical issue, this research use physical rapid stirring method, collocating with the viscosity of two biomaterials to let the particles mixed and suspension in the resin. Then discuss the influence of manufacturing time between maximum concentration of ferrite oxide and different present of photoresist. After investigating the accuracy of forming parameters and forming features, arranging the better formula and analysis the magnetic permeability of all pieces made by two different type of biomaterials. Finally, use the biodegradable material to make complicated, multi-layer structure, which is used to form the bio-scaffolds. According to the experiment, the lower concentration of ferrite oxide powder with 3% of photoresist TPO, the better accuracy of workpiece. The requirement of higher magnetic permeability, the higher concentration, 3% ferrite oxide powder with acceptable accuracy, can results the better magnetic applications.
