System for authenticating an additively manufactured object

DWPI Title: Method for authenticating an additively manufactured object, involves an authenticating of additively manufactured (AM) object, and measurement is obtained that indicatives of stochastic distribution of dopant and incorporated in AM object
Abstract: A method for authenticating an additively manufactured (AM) object is disclosed herein. A computing device obtains a measurement that is indicative of a stochastic distribution of dopant incorporated into the AM object. The computing device generates authentication data for the AM object based upon the measurement, and authenticates the AM object based upon the authentication data.
Use: Method for authenticating an additively manufactured object.
Advantage: The method offers design flexibility, which is not available with traditional machining approaches, and is empowered by software that contributes to properties of additively manufactured units.
Novelty: The method involves an authenticating of an additively manufactured object (102). The measurement is obtained that indicatives of a stochastic distribution of dopant and incorporated in the AM object. The measurement is generated by a measurement device (210) in communication with the computing device (202), where the stochastic distribution of dopant is incorporated in the AM object. The dopant is stochastically distributed in the feed stock material and used to generate the AM object. The dopant is stochastically distributed on a surface of the AM object. The test authentication data is generated for the AM object based on the measurement.
