A review on non-destructive evaluation and characterization of additively manufactured components

One of the most promising manufacturing processes for producing complex geometries in a shorter amount of time is additive manufacturing. However, the majority of additively manufactured industrial components fail to meet their intended specifications. The surface quality achieved by additive manufacturing parts is one of the major concerns of the industries. Furthermore, the additively manufactured components are prone to a wide range of interior and exterior flaws. Non-destructive evaluation has been identified as one of the most effective methods for resolving this issue. This review paper provides an overview of the most common occurring defects in the additive manufactured components, as well as the various non-destructive evaluation methods applicable to additive manufacturing components and their capability to detect and control the defects formed during manufacturing and service of the components. The suitability and challenges of applying non-destructive techniques to various additive manufacturing processes and parts are also discussed in this paper.

Automated summary

Additive manufacturing is a promising process for complex geometries, but often fails to meet specifications due to surface quality issues and various flaws. Non-destructive evaluation is considered to be an effective method to detect and control these defects. This review discusses common defects in additive manufacturing components and the application of non-destructive evaluation methods to address them.
