Abstract
A system and method for manufacturing and authenticating an additively manufactured component are provided. The method includes additively manufacturing the component including a first component identifier. A second component identifier is generated using the first component identifier and an encryption key. The second component identifier is additively manufactured onto the component and the first and second component identifiers are stored in a database as an authenticating pair. An end user may determine that a component is authentic if it contains a first component identifier and a second component identifier that match an authenticating pair from the database.
Claims20
A method of additively manufacturing a component, the method comprising:
- additively manufacturing the component comprising a first component identifier;
- obtaining data indicative of the first component identifier;
- generating, using the first component identifier and an encryption key, a second component identifier;
- and
- additively manufacturing the second component identifier onto the component.
A system for authenticating an additively manufactured component, the system comprising:
- one or more processors;
- and
- one or more memory devices, the one or more memory devices storing computer-readable instructions that when executed by the one or more processors cause the one or more processors to perform operations, the operations comprising:
- obtaining data indicative of a first component identifier of the component;
- generating, using the first component identifier and an encryption key, a second component identifier;
- and
- additively manufacturing the second component identifier onto the component.
The system of claim 14, wherein the operations further comprise recording the first component identifier and the second component identifier as an authenticating pair in a database.
The system of claim 15, wherein the operations further comprise:
- receiving a validation identifier including data indicative of the first component identifier and the second component identifier;
- and
- determining that the component is authentic if the validation identifier corresponds to the authenticating pair from the database.
A method of authenticating an additively manufactured component, the method comprising:
- obtaining a first component identifier and a second component identifier of the component;
- and
- determining that the component is authentic if the first component identifier and the second component identifier correspond to an authenticating pair from a database.
