碩士 / 國立臺灣科技大學 / 機械工程系 / 93 / Up to the present, the fabrication of the micropump generally used the MEMS processes were designed micropump for driving flow simply. This study focused on simple manufacture and inexpensive cost for the meso-scale underwater vehicle’s propulsion and direction auxiliary element. For the demands of the cheap cost, the piezo buzzer which was easily-obtained was the first choices for actuator and DC power supply and frequency controlled circuit were used as the driver. Most of the micro-scale manufacturing processes nowadays was unable to achieve the 3D geometry of vertical channel in our designed; therefore, this study chosed SDM (Shape Deposition Manufacturing) as the most suitable process.
This study designed micropump with three inlet channel and one outlet channel for the application of meso-scale underwater vehicle. The dimensions of micropump are 15mm×15mm×3mm and the channel opening angle is 10 degree. CAD/CAM software was applied to slice 3D model and map out the manufacturing plan appropriately. SDM process utilized casting polymer, wax, and 3-axis CNC processing machinery to make the principle part of the micropump. This study conquered the problem of the manufacture of 3D geometry of vertical channel and part material deformation of the high temperature with support material casting. Finally, this study fabricated the micropump and tested the back pressure and flow rate, and furthermore discussed the improvement of future work according to the results of this study.
