Hyperelastic “bone”

Hyperelastic “bone”: A highly versatile, growth factor–free, osteoregenerative, scalable, and surgically friendly biomaterial Adam EJ et al
What if we could create custom bone implants that would trigger their own replacement with real bone? Jakus and colleagues have done just this with a promising biomaterial that can be 3D-printed into many shapes and easily deployed in the operating room. Made mainly of hydroxyapatite and either polycaprolactone or poly(lactic-co-glycolic acid), this “hyperelastic bone” can be 3D-printed at up to 275 cm3/hour, the authors report.
