Abstract Dynamic cross‐linking waterborne polyurethanes (DCWPU) are gaining increasing attention for their great potential in soft materials, flexible sensors, robotics, and bioelectronic devices. However, achieving a facile straightforward design of strong yet tough, multifunctional, printable DCWPU customizable smart devices is still challenging this field. Here, simple versatile visible‐light‐mediate situ metal‐ligand coordination (VSMC) strategy reported to fabricate high‐performance DCWPU. This photochemical enables the rapid controllable release metal ions from ethylenediaminetetraacetic acid salts, orthogonally triggering classical radical polymerization. The resulting homogeneous metal‐coordinated network significantly enhances stretching strain, stress, toughness reversibility further imparts excellent shape memory, shape‐reconfigurable self‐healing features when exposed heat stimuli. Moreover, efficient VSMC greatly reduces gelation time under 5 s, which improves its printability structural design. Leveraging these advanced performances, application demonstrated. work expected open new avenues
