Abstract
A system and method for manufacturing and authenticating an additively manufactured component are provided. The method includes forming a surface around a cross sectional layer and introducing localized surface variations to the surface. The localized surface variations are configured for generating a unique acoustic wave response that defines a component identifier of the component. The method further includes exciting the surface of the component at an excitation region using an excitation source and interrogating the surface at an excitation region of the component at an interrogation region using a vibration sensor. The acoustic wave response may be compared to a stored component identifier in a database for authenticating components.
