The INTRAPID project aims to develop three NDT techniques for inspection of parts and components manufactured by additive manufacturing processes, in particular laser metal deposition (LMD).

LMD is a technology that has been maturing over the last 20 years and has found application in repair, coatings, hybrid build and 3D near net shape manufacture of small intricate parts that can be used in aero and automobile engines to improve efficiency.

Currently this technology cannot be used to supply some of these parts because absence of flaws that might be left in the component during manufacture cannot be guaranteed. Today, quality is assessed by sample destructive testing, which gives slow feedback and is expensive. Some form of non-contact NDT would be the desired solution so that parts can be made right first time and with reduced cost; however conventional NDT is generally used for mush simpler and larger structures and cannot be adapted easily for these components.
