The effective deployment of Additive Manufacturing (AM) in safety-critical applications is limited due to concerns around part integrity. Non-Destructive Evaluation (NDE) is required to provide assurance if AM is to progress into a mainstream manufacturing process in high-value industries such as aerospace. The non-contact and non-destructive nature of Laser Ultrasonics (LU) is well suited to the online inspection of AM. This paper discusses Laser Induced Phased Arrays (LIPA) as a NDE solution capable of detecting defects and/or features up to 26 mm deep and as small as 0.5 mm in diameter. It also discusses the capability of the system to be used as a quality control tool in terms of internal feature geometrical accuracy.
