A process to fabricate 3D metal microstructure based on UV-LIGA and micro-EDM technology was researched. 2D metal microstructure was fabricated by UV-LIGA technology firstly
and then it was machined using micro-EDM to get 3D metal microstructure. The method takes advantages of high machining accuracy and fabricating 3D metal microstructure with free-form surfaces. 3D nickel mold with trapezium table and taper flute microstructures in part was fabricated. The influence of micro-EDM discharge parameter on surface roughness was analyzed
and the surface roughness was dropped through reducing the discharge voltage and catacitance.
