碩士 === 國立臺灣大學 === 機械工程學研究所 === 102 === Abstract Two-Photon absorption Polymerization (TPP) can be used for micro-structures’ production, which allows accurate manufacturing of complicated three-dimensional structures at the micron or sub-micron levels. It has become well developed enough to offer a reliable fabrication method for micro electro-mechanical systems. Previous researches on TPP were mainly concentrated on the development of photosensitive resins, control of fabrication laser beams, capability of the fabrication of complicated structures and possible new applications (ex. Micro-fluidic chips and bio-scaffolds) of TPP. On the other hand, as to the mechanical properties of the micro-structures, few researches had been done. However, to design a practical machine component with reasonable structural integrity, reliability and functional operability, the mechanical properties must be known. For now, mechanical properties for the resins rely much on the data given by the factory which produces the resins. However, there are researches indicate that after the TPP process, the mechanical properties of the resins might change a lot. Because TPP fabrication has its limitation on the size of the structure, which makes the conventional mechanical testing methods impossible to be applied, and the lacking of the researches about the mechanical properties, the objective of this research is to measure the Young’s Modulus of the structure after the TPP process, and to understand the relationships between Young’s Modulus and some parameters during the production. Moreover, recently TPP is also used for manufacturing the bio-scaffold for the cell culture, but the researches on the mechanical properties of the bio-scaffold are also not enough. So the other half of this research is trying to understand and analyze some mechanical behavior and parameters of the bio-scaffold by Finite Element Method (FEM), and hope to give some ideas to later the production of the bio-scaffold.
