Abstract Scope Tensile samples are often used to qualify builds and materials, however, there is currently no single standard sample geometry for additive manufacturing that is widely adopted to achieve this. While there is already work demonstrating the difference in measured properties between tensile samples produced in different build orientations, this does not extend to different sample geometries. To study the extent of geometry on product qualities for tensile samples, a selection of standard coupon types across the range provided in ASTM E8 and E8M was prepared using an Arcam A2X EBM machine and Ti-6Al-4V as the representative material. These coupons were characterized to observe any porosity defects, dimensional deviations, and surface topography that could impact part performance. This study presents the results of the tensile testing and evaluations of any systematic correlations of mechanical performance with respect to the various sample geometries and sample properties.
