Mixing distinct properties in a single part is essential to developing advanced materials. While additive manufacturing (3D printing) has emerged as a premier route for the creation of these ‘multi-material’ structures, conventional approaches are plagued by complexity, slow build rates, and limited properties. We are developing Solution Mask Liquid Lithography (SMaLL), a technique that takes advantage of different wavelengths (color) of light to define properties. For example, blue light gives a hard material while green light leads to flexible systems. Using this novel strategy we have demonstrated soft joints, brick-and-mortar structures, and tough bio-inspired materials. Further development of SMaLL includes incorporating porosity to expand the range of printable materials.
