However, its widespread application is hindered by insufficient curing within the narrow light\u2010dose processing window, which ultimately compromises the fidelity and stability of the printed hydrogels. To address this challenge, we introduce a peptide self\u2010assembly\u2010mediated polymerization strategy to engineer mechanically reinforced hydrogels that exhibit steep curing immediately following the gelation threshold. In our approach, vinylated self\u2010assembling peptides (vSAPs) are conjugated to tetra\u2010arm polyethylene glycol macromers (vSAP\u2010macromers). The self\u2010assembly of vSAP\u2010macromers induces nanoscale spatial confinement of vinyl groups, which substantially shortens the diffusion distance for radical propagation. Consequently, vSAP\u2010macromers exhibit steep conversion and rapid network formation once the light dose exceeds the polymerization threshold. Moreover, the incorporation of vSAPs induces a potential nanoreinforced network, leading to substantial mechanical reinforcement. Owing to these features, vSAP\u2010macromers ensure the in\u2010process stability of hydrogel constructs under restricted light doses. Consequently, this leads to improvements in both the printing fidelity and mechanical performance of the final TVP\u2010fabricated hydrogels. Collectively, this work offers a generalizable design framework for tailoring high\u2010performance hydrogels for TVP and a solution to resolve the polymerization kinetic mismatch in hydrogel
