Single-vat single-cure grayscale digital light processing 3D printing of materials with large property difference and high stretchability

Despite recent progress in additive manufacturing of organic materials, multimaterial additive manufacturing remains challenging. Here, the authors design a resin design that can be used for singlevat single-cure grayscale digital light processing 3D printing where light intensity can locally control the conversion of monomers to form from a highly stretchable soft organogel to a stiff thermoset within in a single layer of printing
