Title	4D printing of metallic metamaterials for bone implants via biodegradation
Description	4D printing, integrating the temporal dimension into 3D printing, offers transformative potential for bone implants. Yet its application to metallic materials is constrained by the scarcity of suitable alloys and the requirement for harsh external stimuli to trigger shape change. Here, we introduce 4D printed metallic metamaterials (4DMM) driven by controlled biodegradation. The 4DMM combine biodegradable constraints (e.g., Mg or Zn) with biometals of higher corrosion potential (e.g., Ti). Upon electrochemical degradation of the constraint, the metamaterials recover their original geometry—via stretching, bending, or expansion—generating programmable recoil forces tuned through structural design parameters. When developed as scaffolds for bone implants, 4DMM exhibit excellent cytocompatibility and, in vivo, promote superior bone regeneration through the synergistic effects of bioactivity and mechanical stimulation. This strategy establishes a new paradigm in 4D metal printing via metamaterial design, enabling bioactive, self-restoring implants with broad applicability across biomedical engineering.
