文摘
- •
PLA/15%HA scaffolds with recovery stress of 3.0 MPa were obtained by 3D-printing.
- •
HA particles act as nucleation centers and form an additional rigid fixed phase.
- •
HA particles inhibit growth of cracks during compression-heating-compression cycles.
- •
SME results in “self-healing” by narrowing the cracks with shape recovery of 98%.
- •
PLA/15%HA porous scaffolds may be used as self-fitting bone implants.
