碩士 === 國立臺灣科技大學 === 機械工程系 === 104 === 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.
