Optimization of TCP/HAP ratio for better properties of calcium phosphate scaffold via selective laser sintering

► Porous ceramic scaffolds with different ratios of TCP/HAP were fabricated by SLS. ► BCP scaffolds exhibit better mechanical properties than HAP or TCP scaffolds. ► The bioactivity of scaffolds can be controlled by adjusting the TCP/HAP ratio. ► TCP/HAP(30/70) exhibit optimal comprehensive properties.
