This study aims to determine the mechanical properties and Vicker microhardness of a Ti- 6Al-4V alloy. This article presents all the experimental work from titanium alloy specimens manufacturing by Selective Laser Melting to the mechanical and Vicker microhardness tests. The additive manufacturing parameters were studied. It was concluded that the powder preparation and conditioning cycle in this process is crucial to obtaining the material. Elastic and plastic mechanical properties were obtained to fill the gap in the scientific community, particularly concerning values for the ductility exponent, strength coefficient, resilience, and toughness. From the microhardness study, it was concluded that the values obtained in the cross-section are 5.65% higher than in the longitudinal section.
