This study explores the fabrication of bone scaffolds using a composite ink poly-ε-caprolactone (PCL), polyhydroxybutyrate (PHB) and synthesized fluorapatite (FHAp) via response surface methodology optimization to achieve optimal Vickers hardness number (VHN). Characterization with X-ray diffraction confirms FHAp presence increased crystallinity post-sintering, while Fourier-transform infrared spectroscopy reveals fundamental material interactions. Results show PCL’s softening effect at higher concentrations, PHB’s contribution decreasing FHAp’s significant role in reinforcing composite. Contour plots demonstrate peak lower PCL PHB concentrations (<11% wt/v) 18% wt/v FHAp. The optimum values were found PCL, 9.754% wt/v, 9.473% 24.608% respectively, yielding 185.34 VHN.

Bone regeneration often fails due to implants/grafts lacking vascular supply, causing necrotic tissue and poor integration. Microsurgical techniques are used overcome this issue, allowing the graft anastomose. These have limitations, including severe patient morbidity current research focuses on stimulating angiogenesis in situ using growth factors, presenting such as a lack of control increased costs. Non-biological stimuli necessary promote for successful bone constructs.
