Abstract

As additive manufacturing (AM) moves towards industrial production in critical sectors such as aerospace and medical, the integrity of the fabricated AM parts need to be ensured in order for these parts to be certified. This requires quality controls, including non-destructive testing(NDT), to be implemented. AM enables fabricating very complex parts which are not possible to manufacture with conventional manufacturing methods. This can pose a great challenge for existing NDT technologies to perform their inspection. Thus, the existing NDT techniques need to be evaluated with complex AM parts. This paper presents the evaluation of two promising NDT methods for AM: a resonant acoustics method (RAM) and a phased array ultrasonic testing (PAUT) method involving a full matrix capture (FMC)acquisition procedure, and a total focused method (TFM) to post-process the data and reconstruct the images.
