 to assess the impact of specimen size on the tensile properties of additively manufactured T6ol for V components, various rectangular specimens ranging from miniaturized to ASTM standard are machined and tested. The results show that elongation is strongly related to sample size while yield an ultimate tensile strength exhibit an independent feature. Three factors, including poor location, size and segregation, as well as slimness ratio, have a synergic influence on elongation for different specimen sizes with varying cross-sectional area. Microscale tests may introduce uncertainties in measurement that must be considered when discriminating material behavior. The experimental results provided guideline for designing and testing non-standard specimens for AM components.
