| Abstract Scope |
Open-structured metallic scaffolds allow mechanical and biomedical properties to be tailored to specific needs. Although open architectures reduce strength relative to bulk material, they permit the infiltration of functional polymers that promote bone growth and limit inflammatory response. To assess the influence of metal ratio on mechanical behaviour and on polymer infiltration, Zn-0.1Li powder was used to produce round open scaffolds with varying mantle thickness and grit size. Zn-0.1Li was selected for its comparatively high strength and deformation capacity. The voids were filled with PCL composites containing 30 wt% and 80 wt% HA/β-TCP in order to quantify the reinforcing contribution of hydroxyapatite, with further options such as silver nano-crystals for antibacterial function. Mechanical properties decrease markedly depending on metal ratio, grid and void size, and filler constitution; these dependencies are discussed. |
