3D printing of polylactic acid/poly ethylene glycol/hydroxyapatite porous bone scaffolds and their biocompatibility

3D printing of polylactic acid/poly ethylene glycol/hydroxyapatite porous bone scaffolds and their biocompatibility

Polylactic acid (PLA) is a widely used biopolymer material. However, there are disadvantages such as poor toughness, poor hydrophilicity, and poor biological activity in the application process. It was modified with polyethylene glycol (PEG) and hydroxyapatite (HA).3D printing filaments of PLA/PEG/H...
