Abstract

We propose a single-exposure generation of free-standing 3D microstructure by vertically rotating photo-patterned top-view with the capillary force of liquid. Instead of expensive direct writing for cross-sectional patterning, we pattern the top-view of the structure using projection lithography and rotate the plane 90 degrees to stand vertically. As a result, high throughput fabrication of 3D polymeric microstructures is achieved in a cost-effective way.
