Thermoplastics, a kind of polymer that undergoes reversible solid-to-liquid like transitions triggered by solvents and/or heat, are a commonly utilized feedstock for DIW . However, most thermoplastics are inherently stiff with Young's modulus greater than 10 6 Pa , which restricts the range of applications for 3D printable elastomers. To overcome this limitation, leveraging the selfassembly of responsive bottlebrush-based triblock copolymers, we previously developed a class of soft elastomers suitable for DIW printing . However, making these elastomers suitable for DIW requires dissolving the polymers into solvent. After deposition, the solvent evaporates, leading to volumetric shrinkage and warping in the printed structures and ultimately reducing print fidelity.
