碩士 === 國立臺灣科技大學 === 高分子工程系 === 92 === The study of major is advancing the applications of the resin that using in Rapid Prototyping system. It　was focused on disadvantages of over curing, not precise, shrinkage, and mechanical strength. Due to the advantage of nano-powder (SiO2, Carbon Black) with high surface area and high activation, it’s can be easy to combine with the resin. Add nano-powder (SiO2, Carbon black) to the resin Tetrafunction Polyester Acrylate (TPA) / 1,6-Hexanediol Diacrylate (HDDA), to solve question of the defect. The result point to add dispers to the resin could disperse the nano-powder in TPA/HDDA be Nano-composites. TPA/HDDA Nano-composites could increase the mechanical strength to 50%. TPA/HDDA Nano-composites can decrease shrinkage to 20%. When Disperse rate at 1:10~1:15 can effective in control the depth.
