Abstract 3D‐printed polymer‐based composites are promising for various engineering applications due to high strength‐to‐weight ratios and design flexibility. However, conventional matrix materials, such as polylactic acid epoxy resin, often exhibit brittleness limited impact resistance (< 10 kJ m − 2 ). Herein, a universal strategy is reported enhancing the ductility energy absorption of by leveraging dynamic crosslinking B─O dative bonds. To validate its effectiveness, smart composite (PLA/SSG) comprising shear‐stiffening gel fillers embedded in designed rate‐dependent mechanical adjustability along with 3D printability evaluated. The resulting shows significant improvements resistance, ductility, strength‐ductility balance. Specifically, multiple crack localized plastic yielding induced enables PLA/SSG 40‐times increase ductility; “soft‐hard” phase transition bonds endows 330% improvement absorption. This bonds‐inspired provides approach printing impact‐resistant structures.
