Story summary

Researchers at Tampere University 3D-printed hydroxyapatite bone scaffolds with ~400 µm pores and ~45 % porosity.
The HAp2 scaffold showed the strongest collagen network, highest osteocalcin, and best bone formation.
Sintering at 1000 °C gave the best balance of strength and cell attachment, while 1300 °C blocked adhesion.
AI models can generate new metamaterial implant designs in minutes, including electrically expandable scaffolds, to meet demand from over 2 million bone-graft surgeries each year.
