Titanium and its alloy, especially Ti6Al4V is one of the most widely used metal due to its excellent properties. Selective laser melting, which is known as additive manufacturing is considered as a suitable method to manufacture Ti6Al4V parts. To print a more analogous Ti6Al4V artificial bone, laser power was changed by taking volume porosity, corrosion resistance and wear resistance into consideration. The testing results showed that sample printed using 200 W showed a relative optimal corrosion resistance and volume porosity in all these five samples (the value of corrosion voltage is - 0.352 V), while it showed the best bio-tribological behavior, and its wear volume is as low as 5.90 mu m(3). Summarize the 5 sets of experimental samples, the Ti6Al4V part printed using 180-200 W were the most prominent in the test, its overall performance was, indeed, best fit to print artificial Ti6Al4V bone, because it is similar to bone, there are a large number of microporous structures.
