Summary:A new triply periodic minimal surface (TPMS) structure mimicking the microstructure of Great Spotted Woodpecker's cranial bone was designed, fabricated and tested in this study. It was found that the designed structures acquired better mechanical performance compared to the unit structures applied in heterogeneous porous scaffolds. The wall thickness mimicking the woodpecker's spongy bone and the TPMS surface structure were two contributors to the good mechanical performance of new designed bionic structures.
