Transplantation of bone implants is currently recognized as one the most effective means treating defects. Biobased and biodegradable polyester composites combine good mechanical degradable properties polyester, thereby providing an alternative for implant materials. Bone tissue engineering (BTE) accelerates defect repair by simulating microenvironment. Composite scaffolds support formation further accelerate process repair. The introduction 3D printing technology enables preparation to be more precise, reproducible, flexible, which a very promising development. This review presents physical BTE summarizes strategies adopted domestic international scholars improve based on biobased polyester/ceramic in recent years. In addition, future development prospects field challenges expanding production clinical applications are presented.

Porous materials, owing to their unique pore networks, are expected positively influence the enhancement of mechanical properties and modulation degradation behavior. Herein, composite scaffolds were fabricated by a combination triply periodic minimal surfaces (TPMS) design, selective laser sintering (SLS), hot-pressing technology, in which iron foam (FFe) polycaprolactone (PCL) reinforcing phase matrix, respectively. Mechanical strengthening was achieved forming an interpenetrating structure between continuously porous FFe TPMS PCL. Regarding regulation, catalytic microcirculation system (CDMS) constructed through acid-base neutralization reactions PCL products. The results indicated that compressive tensile moduli increased astonishing 1758.8% 466.0% compared with scaffold, is attributed synergistic load sharing stress transmission efficiency structures. In addition, weight loss scaffold 3.6 times higher than indicating CDMS achieve regulation. Encouragingly, also exhibited good apatite induction ability during vitro culture. Therefore, realizes regulation properties, so it has potential applications bone tissue engineering.

Physical stimulations such as mechanical and electric stimulation can continuously work on bone defect locations to maintain enhance cell activity, it has become a hotspot for research in the field of repair. Herein, bifunctional porous composite scaffolds with shape memory piezoelectric functions were fabricated using thermoplastic polyurethane (TPU) poly(vinylidene fluoride) through triply periodic minimal surfaces design selective laser sintering technology. Thereinto, fixity ratio recovery scaffold reached 98.6% 81.2%, respectively, showing excellent functions. More importantly, its coefficient (d33 = 2.47 pC/N) is close constant tissue 0.7–2.3 pC/N), voltage released during compression process reach 0.5 V. Furthermore, cyclic experiments showed that strength was up 8.3 times compared TPU scaffold. Besides, cytocompatibility. In conclusion, expected generate due function, which provide an effective strategy
