| Summary: | 碩士 === 國立交通大學 === 機械工程系所 === 105 === In this paper, we combine selective laser sintering with real-time 3D NURBS curve interpolator. Using the characteristic of silver nanoparticle has a great absorption rate at a specific wavelength. Choosing the 532 nm laser system to explore how to sintering the silver nanoparticle that coating on the flexible substrate. Utilizing the NURBS curve interpolator to replace the linear approximation curve as the laser sin-tering path. To avoid the linear approximation curve cause the speed change greatly and lead to destroy flexible substrate by local heat accumulation. It will bring the poor sintering result.
Aim the laser power from 300 mW to 1000 mW and the laser scanning speed from 100 mm/min to 600 mm/min respectively to test the appropriate laser parameters for silver nanoparticle sintering. Verify after sintering, the optimum sheet resistance can reduce from 670 mΩ/□ to 209 mΩ/□. Then combine the 3D NURBS curve interpolator as the laser sintering path to enhance the conductivity of silver nanoparti-cle after sintering and implement this concept in 3D. Finally, a spatial spiral curve is demonstrated.
