| Abstract Scope |
As additive manufacturing (AM) techniques are more frequently adopted for the fabrication of parts in load bearing applications, the understanding of how reproducible parts are is important for the acceptance of AM by industries. Similar machines having different serial numbers are expected to yield parts with the same mechanical properties however, this may not be the case if machines have not been adequately qualified and maintained, emphasizing the need for proper process qualification and quality control. This study aims to assess the effects of machine-to-machine variability on the tensile behavior of Ti-6Al-4V fabricated on two Velo 3D Sapphire machines at different locations. Results showed that tensile properties were comparable across both builds. The most noticeable differences were observed in the ductility of the material which showed some location dependence. The location dependence, however, was the same for both machines. |
