| Abstract Scope |
The combination of calcium phosphates (CaPs), such as hydroxyapatite (HA), with polylactic acid (PLA) represents an effective strategy for the development of composite biomaterials with applications in bone tissue engineering. While CaPs provide bioactivity and osteoconductivity, PLA offers good mechanical properties and processability. This synergy facilitates the fabrication of customized scaffolds by additive manufacturing. In this context, HA was synthesized from eggshells and biogenic sulfuric acid, proposing a sustainable and low-cost way to obtain bioactive materials. The HA-PLA blends were processed by extrusion and characterized morphologically (using SEM) and mechanically. Strength, stiffness and deformation properties were evaluated, and it was observed that the incorporation of HA significantly modified the mechanical behavior of PLA, suggesting an improvement in the bioactivity of the material without compromising its processability. These results demonstrate the potential of HA-PLA composite for applications in tissue engineering, especially in the fabrication of personal bone structures. |
