摘要

A new direct-laser-writing (DLW) approach was developed in this study, incorporating the following design theories to refine the initial design idea: the theory of inventive problem solving (TRIZ), axiomatic design, SWOT analysis (strengths, weaknesses, opportunities, and threats), and system diagrams. These theories were selected to maximize the efficiency and creativity of DLW, and their integrated application aided in establishing the new process in a rapid, economical manner. Overall, the present study explored the ways in which these design theories could be exploited to develop a creative, practical DLW system. From the several design theories, the new concept of DLW, a hybrid of two-photon lithography and the multidirectional ablation process, was proposed. The 3D microstructure is fabricated by TPL, and the multidirectional ablation process is used for the post-processing to enhance the fabrication ability of various 3D microstructures. The proposed DLW is expected to overcome the limitations of existing fabrication processes in terms of flexibility and enable increased diversity in fabrication.
