Abstract
Methods and systems for fabricating a micro-structured biomaterial include printing a three-dimensional structure using polymerizing radiation modulated by a digital micromirror array to project microstructure patterns into a pre-polymer material to form one or more porous scaffold sheets. The microstructure patterns have a unit-cell geometry that exhibits a negative Poisson ratio that is tunable in magnitude.
