To meet the increasing demand for bone scaffolds, advancements in 3D printing have significantly impacted bone tissue engineering. However, the materials used must closely mimic the biological components and structural characteristics of natural bone tissue. Additionally, constructing complex, oblique structures presents considerable challenges. To address these issues, we explored 3D bioceramic printing using a sanitizer-based hydrogel. Collagen, a primary component of the bone extracellular matrix (ECM), was combined with alpha-tricalcium phosphate (
