colorful microstructures

Caption

Printed 2D and 3D microstructures in different structural colors. (A) Logo of 2D Max Planck Society in different colors. The patterns are printed at different driving electric fields, yielding different structural colors. (B) 2D Taiji logo in various colors and combinations. The patterns of different sizes are printed to test the resin's printing resolution limit. A pattern can be printed in different colors by selectively printing certain parts at one driving electric field strength and other parts at a different driving electric field strength. (C) 3D microscale frames. The frames are printed in liquid crystal cells with a 65 μm gap at different driving electric field strengths.
