The aim is to improve the performance of DLP inks in bone tissue engineering by integrating calcium phosphate oligomers and optimizing crosslinking processes.
Replaced conventional calcium phosphate particles with highly water-soluble calcium phosphate oligomers (CPO) for better dispersion.
Developed a hybrid structure by concurrent GelMA crosslinking and CPO crystallization during printing.
Characterized the printability and mechanical properties of various ink formulations, particularly focusing on 20% CPO (GC-20).
Ink containing 20% CPO showed superior printability and mechanical properties compared to traditional formulations.
Scaffolds converted CPO to hydroxyapatite (HAp), achieving a significantly improved compressive modulus and toughness.
In vitro tests revealed that scaffolds promote cell proliferation, adhesion, and enhance osteogenic differentiation and mineralization.
