Study the mechanical properties of the SLM fabricated titanium parts built in a horizontal direction, i.e. parallel to the substrate, in a real, as-built condition has always been a challenge because of parts distortion. For that reason, the mechanical performance of SLM fabricated titanium parts in their truly as-built condition has not been fully investigated. By developing a new design procedure that enables fabrication of straight horizontal parts, the mechanical properties of horizontal Ti-6Al-4V samples in their truly as-built condition has been reported and compared with their vertically built counterparts. In addition to the truly, as-built condition, the effect of machining was also studied to further highlight the effect of as-built surface removal on the mechanical properties of both vertically and horizontally deposited Ti-6Al-4V SLM parts. This study provides a better understanding of the effect of as-built surface on the mechanical properties of SLM fabricated parts in two build directions.
