| Summary: | 碩士 === 國立臺灣大學 === 機械工程學研究所 === 107 === 3D printing technology has developed rapidly, which can print from large objects to smaller and smaller microstructures. Now which can make nanostructure is TPP (Two-photon Polymerization). Our research is how to make the same effect as Two-photon Polymerization by using DLP (Digital Light Processing) Vat Polymerization. Two-photon Polymerization consumes more time than Digital Light Processing . And the equipment be used in Digital Light Processing are more cheaper than Two-photon Polymerization. We try to adjust the lens of DLP projector which can reduce the image, but we also meet the problem which is keeping the high resolution when reducing the image.
Design the model of octet-truss by Digital Light Processing Vat Polymerization printing. We try to make the micro-scale structure by adjusting the influence which contain structure size, DB composition, exposure time and cutting thickness. And we test the compressive strength of the octet-truss structure. In addition, we want to make our structure stronger. Therefore we use the Electroless Ni on our octet-truss structure. But our material is macromolecule so we should use surface treatment. Also the surface treatment has four different methods in our processing. Discuss the effect of the four surface treatment on Electroless Ni
