High-resolution 3D printing of modified pullulan elastic hydrogels via solvent-induced shrinkage.
3D-printable hydrogels confront two core bottlenecks: the trade-off among high printing resolution, fabrication efficiency, and structural fidelity, as well as the inherently poor mechanical performance of conventional hydrogel materials. Herein, we fabricated a dual-network photo-crosslinkable pullulan-based hydrogel...
