This study investigated the effect of the processing parameters on the quality and mechanical properties of a biomedical titanium alloy (Ti-24Nb-4Zr-8Sn) scaffolds fabricated by selective laser melting. Optimal manufacturing parameters were then determined through analysing the pores distribution, geometrical accuracy and the mechanical properties of the produced components. The evaporation of tin during the process is thought to be the main cause of pore generation at higher incident energy densities. Using the optimal processing conditions, the strength of the scaffold reached 51 MPa at a scaffold density of <1 g/cm(3) and a high solid strut relative density of 99.3%. Fracture surface analysis found that the main reason for strut early failure was the weaknesses of struts caused by the presence of pores as well the thickness of strut and internal unmelted powders.
