Abstract
An exemplary additive manufacturing method includes receiving a build file comprising instructions for controlling the manufacturing hardware to generate an object, receiving a material identifier indicating a particular lot of manufacturing media, validating the build file and the material identifier via a distributed ledger to verify both an author of the build file and an origin of the particular lot of manufacturing media, causing manufacturing hardware to generate the object using the build file and the particular lot of manufacturing media, generating an object manufactured transaction to the distributed ledger indicating a result of the validation of the origin of the at least one of the build file or the material identifier, and certifying the object in response to verifying the author of the build file and the origin of the particular lot of manufacturing media, and wherein the object manufactured transaction indicates that the object is certified.
