    Abstract: 本論文發展一套適合雙光子聚合技術(Two-photon Polymerization, TPP)之五軸雷射加工路徑生成法則。
    ;This paper studies the laser tool path generation for 5-axis micro-fabrication system by Two-photon Polymerization(TPP).
    At the beginning of this paper, there is an introduction about the laser scanning path by traditional TPP, slicing method and product properties by TPP. Second, we will go on to the introduction about the experimental equipment for 5-axis based on the TPP with laser, microscope, resin material and motion platform by 5-axis. Furthermore, the paper presents the development of the laser tool path generation for 5-axis micro-fabrication system.
    This paper will develop a laser tool path generation for fabricating structures with ultra-precision based on TPP micro-fabrication and 5-axis machining techniques. Laser tool path generation will be developed using the critical slicing angle to distinguish between two different area. Using the Patch concept were to produce two different area of the Sheet fabric and Sewing fabric. In this method, adaptive slicing process to generation the Sheet path and using the contour offset algorithm to generation the Sewing path. Finally, the contour will be tangential axis forming method to produce the final laser tool path for 5-axis micro-fabrication system. In this method, the laser focus moves along the vertical contour of a microstructure by 5-axis motion stage and polymerized at the perpendicular direction of the tangent. This can avoid the dimensional deformation which is usually caused by applying 3-axis stage in general. The 3D microstructure fabricated by proposed process has better structure strength and ultra-high dimensional accuracy, that can suit for a variety of applications.
    Finally, this paper will include 5 different models, using the development of the laser tool path generation for 5-axis micro-fabrication system in this paper to generate the laser scanning path. It can to verify the accuracy and efficiency of this paper.
