Development and Evaluation of Applications Using Micro-stereolithography Technology

마이크로 광 조형기술을 이용한 3차원 형태의 응용제품 제작 및 이의 평가

The micro-stereolithography technology made it possible to fabricate a freeform 3D micro-structure. Using this technology, two kind of applications were fabricated and tested: micro-lens and micro-mixers. The focal length and f-number of the micro-lens were 5 mm and 2.5, respectively. The focusing ability of the micro-lens was verified by defocusing the He-Ne laser beam after passing the lens. Two mixers are Kenics micro-mixer and BEKM. BEKM is a modified Kenics micro-mixer by introducing barriers on the pipe walt periodically to enhance the mixing via the chaotic mechanism in the helical flow of Kenics micro-mixer. Experimental result shows good mixing performance of developed mixers. Especially, the BEKM shows better mixing performance then Kenics micro-mixer.
