To maintain shape-fidelity of the printed constructs, it is vital for the ink to regain its original properties following extrusion. Immediate flow discontinuation and buildup of internal resistance after deposition is crucial to prevent undesirable flows and loss of form prior to secondary photocrosslinking. The time required for returning to the equilibrium state is referred to as the recovery or the self-healing time . Post-printing viscosity recovery (i.e., transition from fluidlike flow to elastic shape retention) of 22 °C GelMA and 37 °C GelMA/bPE inks was studied by applying a high shear rate on the inks, immediately followed by a low shear rate, to simulate the dispensing process (Figure ). GelMA inks exhibited slow recovery kinetics (≥ 8 min) at 22 °C, owing to the long recovery timescale of the triple helix microstructure. In typical printing setups, the print bed is therefore cooled to temperatures below the gelling point of gelatin (17 °C) to accelerate gelation upon deposition. In contrast, both GelMA/DbPE and GelMA/TbPE inks displayed near-instant viscosity recovery at 37 °C (80% recovery within 20 s), resulting from the rapid recovery of the PEC self-assemblies.
