The projection dynamic mask lithography system. Designed gray-scale patterns were controlled and displayed on DMD (Digital Micromirror Device) by computer. UV light was shined onto the DMD patterns and projected to the sample containing aECM-N3 precursor proteins. Gradient distribution of light intensity on the sample fabricated gradient proteins patterns in 2D or 3D
