Secure and traceable manufactured parts

A method for the verification and authentication of additive manufactured product using a plurality of computing devices, a plurality of 3D additive printers, and a distributed transaction register, wherein the distributed transaction register comprises a blockchain, a plurality of nodes at different locations each with a copy of a ledger, comprising the steps of:

• receiving, by a first computing device of the plurality of the computing devices, at least one customer requirement for a product;
• developing, by said first computing device, from said at least one customer requirement, at least one manufacturing requirement for said product;
• generating, by said first computing device, from said manufacturing requirement, a product geometry file and at least one printer parameter;
• recording, by said first computing device, a transaction based on said at least one manufacturing requirement to the distributed transaction register, wherein recording said transaction to the distributed transaction register further comprises recording said transaction to a first block of said blockchain;
• obtaining, by said first computing device, an output from said distributed transaction register in response to said recording said transaction on said distributed transaction register;
• recording, by said first computing device, a first transaction based on said product geometry file to the distributed transaction register;
• obtaining, by said first computing device, a first output from said distributed transaction register in response to said recording said first transaction on the distributed transaction register;
• generating, by said first computing device, a unique code based on said first output;
• receiving, by a 3D additive printer of the plurality of the 3D additive printers, said product geometry file and said unique code;
• printing, by said 3D additive printer, a product using the product geometry file;
• embedding, by said 3D additive printer, within or affixing to said product said unique code;
• receiving, by a second computing device of the plurality of the computing devices, an indication that said product has been printed by said 3D additive printer, wherein the indication comprises said output and said first output;
• recording, by said second computing device, to said distributed transaction register, a second transaction based on said printing of said product and said first output;
• obtaining, by said second computing device, a second output from said distributed transaction register that is associated with said second transaction;
• verifying, by said second computing device and using said unique code, said output, said first output and said second output, that said product was printed according to the at least one manufacturing requirement;
• and
• authenticating, by said second computing device, said product based on the verifying.
