| Summary: | 碩士 === 國立臺北科技大學 === 製造科技研究所 === 102 === The aim of this paper is to study the feasibility of fabricating stainless components with high density by the slurry-based additive manufacturing technique. The metal slurry is easy sedimentation, so layer paving should accomplished by a paving mechanism with a capability of anti-sedimentation to build the green components. The initial study is the mechanism improvement, and then the process study follows.
Based on the existing the system, current study is to enhance the stability of the paving and realize the automation. The improvement of mechanism includes the replacing the main parts, simplifying the system, and installing the automation devices. At last, the optimal paving parmeters can be found through the experiments. In the previous studies, the density of the component built with coarse powder was poor. Current study included fabrication of components with slurry which were added two kinds of fine powder, and observation of component density.
The study reveals the improved paing system sloved the sedmimentation problem and realized the system automation. The slurry method can build the 2.5D components with sample geometry. The component built with fine powder possesses a higher density than that of the componet made of coarse powder.
