Additive Manufacturing technology is facing implementation challenges for airframe production. This is mainly due to lack of generic economic quality control methods to detect defects that compromise fatigue strength. The study done by an experimental campaign with Micro-CT inspections & SEM/Fractographic failure analyses, presents defect characteristics to be detected, for Ti-6AL-4V PBF via SLM.
