本研究專注於利用數位光處理（Digital light processing, DLP）列印技術制備原子力顯微鏡（Atomic Force Microscopy, AFM）探針，以克服傳統製造方法昂貴且耗時的缺點。本團隊之前的工作已成功地證明使用DLP列印製造AFM探針的可行性，在此基礎上，本研究旨完善並優化前人提出的製造方法。
在優化過程中，本研究先以光圈作為變量來調整列印參數，以達到更好的列印效果。觀察到光電流和固化時間對不同尺度的物件大小精度產生影響。在樹脂配方方面，透過在純樹脂中添加黑色顏料和二氧化鈦（TiO2）進行了改良，以改變外觀和光起始劑的含量，從而減少列印時間並解決過固化問題。實驗結果顯示，加入黑色顏料可以增強列印清晰度，但會導致層狀結構更加明顯。而TiO2顏料會引起過固化問題，但有助於減少階梯狀特徵並縮短固化時間。另外，本研究也進一步修改了懸臂樑的設計，以提高列印成功率和改善懸臂樑的壽命，並且對修改後的設計進行了模擬，以計算彈性系數的變化和應力集中的改善。最後，本研究利用製作出來的探針進行掃描，以驗證所製備出之探針的可行性。
綜上所述，本研究探討了以DLP製造AFM探針的潛力，優化了列印參數、樹脂配方和懸臂樑設計等各個方面，以提高製造過程和改進探針性能。

This study focuses on the fabrication of Atomic Force Microscopy (AFM) probes using digital light processing (DLP) printing as a potential alternative to the expensive and time-consuming traditional fabrication methods. The previous work conducted by our team successfully demonstrated the feasibility of using DLP printing for AFM probe manufacturing. Building upon this prior experience, the current research aims to Improve the proposed fabrication method.
Regarding the printing parameters, an aperture variable was introduced during the Improvement process to achieve improved printing results. It was observed that the light current and curing time had an impact on the size accuracy of features at different scales.
In terms of resin formulation, modifications were made by adding resin pigment black ink and TiO2 to the pure resin. This was done to alter the appearance and amount of photoinitiator, aiming to reduce printing time and address overcuring issues. The inclusion of black ink was found to enhance the sharpness of printed features but led to more pronounced stair-step features. On the other hand, TiO2 pigment caused overcuring issues but helped reduce stair-step features and required less curing time.
The research also focused on modifying the cantilever design to increase the success rate of printing and improve the lifespan of the cantilever. Simulation was performed on the modified design to demonstrate the changes in the spring constant and the improvement of stress concentration. Finally, scanning was conducted to showcase the feasibility of applying the fabricated probes.
Overall, this study explores the potential of DLP printing as a method for fabricating AFM probes, optimizing various aspects including printing parameters, resin formulation, and cantilever design, to enhance the manufacturing process and improve the probe's performance.
