Photocrosslinkable nanocomposite ink for printing strong, biodegradable and bioactive bone graft

3D printing is known as a cost-effective technique that shows huge potential in fabrication of graft substitutes for bone tissue regeneration. However, the tradeoff between 3D printability, mechanical strength and bioactivity of the printed materials (i.e., inks) remains a challenge. In this work, we present a novel photocrosslinkable nanocomposite ink composed of tri-block poly (lactide-co-propylene glycol-co-lactide) dimethacrylate (PmLnDMA, m...
