The objective of this research is to examine the design, qualification, and performance of additive manufactured (AM) parts made using ABS-P430 polymer material. A group of tensile and fatigue coupons were designed and manufactured using two fused deposition additive manufacturing machines, Stratasys SST 1200es and Creality CR-10. The AM parts were built on flat and on edge side at different build orientations.The influence of the manufacturing parameters on the mechanical properties of AM components were investigated. This includes the variation in building orientations, layer thickness and the distribution of air gaps.Tensile tests were performed to ascertain the tensile properties of the AM polymer parts. Full field strain measurements were obtained using 2D digital image correlation (2D-DIC). The strain measurement results obtained from DIC were validated with the strain measurements measured by an extensometer. Excellent agreement was found when comparing the results of strain measurements obtained by extensometer to the strain measurements recorded by DIC system. In addition, it was found that the print layer thickness played a significant role in the tensile properties. ANOVA statistical results showed that building orientations influenced the ultimate tensile strength and Young's modulus. There is a slight difference in the tensile properties with the variation in building orientation that is probably not statistically significant. The uncertainty propagation in tensile properties associated with the measuring instruments was calculated using the Guide of Uncertainty Measurement (GUM).
