Abstract: Selective laser melting (SLM) is an additive manufacturing technique,through which functional, complex parts can be created directly by selectively melting metal powders. The influence of the processing parameters on the forming characteristics of metallic powder fabricated by SLM was discussed. The surface features, density, micro-hardness and microstructure were investigated by stereomicroscope, light optical microscopy, scanning electron microscope(SEM), microhardness tester in order to evaluate the forming quality of Ti-6Al-4V alloy fabricated by SLM with different scanning power (P), scanning speed (V), scanning width (S). The results indicated that Ti-6Al-4V fabricated by SLM with the parameters of P=450 W, V=2 500 mm/s, S=0.07 mm could obtain good surface quality, the density could reach 97.8%, the average micro-hardness was 446HV.
