A composition for three-dimensional printing includes a precursor to a soft polymer block having a glass transition temperature (T g ) less than 50°C and a precursor to a rigid polymer block having a T g of at least 50°C. The precursor to the soft polymer block is a curable, cross-linkable monomer having an acrylic group, a vinyl group, or combinations thereof. The precursor to the rigid polymer block is a second curable, cross-linkable monomer selected from the group consisting of an acrylate monomer, a vinyl monomer, an acrylamide monomer, a urethane monomer, and an epoxy monomer. |
