N2 - Within this study, additively manufactured (AM) polyamide samples were locally reinforced with 1,5K endless carbon fiber to modify the achievable bending stress and the load bearing capability under temperature. Using non- destructive testing methods, it was shown that a void gradient exists within the manufactured samples not only within the build-plate plane, but also in build height direction. This gradient was detected using automated grey-scale analysis of section cuts generated using three-dimensional computational tomography. The interaction analysis of the performed coupon tests showed dependencies between the relative fiber content and the extrusion direction of the supporting thermoplastic polyamide matrix material.
