• -based biomaterials are widely used in bone tissue engineering due to their superior biocompatibility and cell proliferation ability. In addition, biodegradability and higher mechanical strength make them more versatile to be used as a synthetic bone implant. In addition, silica-based tailored materials

• biocompatibility with osteoblast stem cells. Chitosan with hydroxyapatite were used to 3D print the scaffolds used to improve the mechanical strength of the bone implant. These dense and cylindrical structures of Ø 10 × 10 mm were 3D printed and 40 wt % lactic acid was used as the binder solution. The results show
