摘要:	雙光子吸收光致聚合微製造技術(Micro-manufacturing Technology of Two-photon Absorption Photopolymerization)是一個可以製作任意外形之三維立體微結構的技術，可運用領域廣泛，因而成為熱門之研究。TPP微製造因其製作材料與材料強度的問題，通常運用於微奈米級尺寸之製造，當要製作高深寬比或相對大尺寸物體之結構在以溶劑洗滌未被聚合的樹酯時，常會因為表面張力發生倒塌等結構破壞之現象，增加結構體的壁厚是一個可行的辦法，但製造時間將會呈倍數增加，且過密的曝光亦可能發生過度聚合產生尺寸不精確甚至發生微爆炸。因此本論文開發了螺旋路徑結構增強演算法在顧及製造效率之外又能達到加強結構強度之目的，並在生成雷射掃描路徑時，規劃在結構外表產生平順的螺旋過度線，以保持物體輪廓外觀完整。而在最後本文以幾個範例顯示此方法增強之結構。;Due to Two-Photon Polymerization(TPP) micro-fabrication technology, in any three-dimensional complex shape and structure can be made in micro/nano scale ,it can be used in a wide range of fields. There, TPP micro-fabrication has become a popular issue. Because of materials and its strength problems, TPP micro-fabrication is usually used to manufacture objects in micro-nano size. When the structure of the object has high aspect ratio or relative large size and being washed the unpolymerized resin with solvent, the surface tension will destroy the structure. Increasing the thick of wall is a feasible method but the time of manufacturing will increase exponentially. Due to the excessive exposure, the structure will be excessively polymeric. Lead to imprecise of the size of the structure and cause micro explosion. This paper developed an rotation path algorithm to increase its wall thickness and take into account the manufacturing efficiency to strengthen the structure . Furthermore, let the path smooth and maintain the appearance of a complete contours while planning its laser path. And in the end of this paper, this method of enhancing the structure will be demonstrated with a few examples.
