System and method for authenticating an additively manufactured component

Abstract:

A system and method for authenticating an additively manufactured component is provided. The method includes locating an identifying region of the component that includes localized density variations that define a component identifier. The method further includes interrogating the identifying region of the component using a scanning device such as an x-ray computed tomography device to obtain the component identifier. The method further includes obtaining a reference identifier from a database, comparing the component identifier to the reference identifier, and determining that the component is authentic if the component identifier matches the reference identifier.
