Abstract

Blockchain-enabled advanced shipment notice for additive manufacturing supply chain is disclosed herein. An example method includes generating a digital supply item associated with a product model for a part, encrypting the digital supply item, generating an additive manufacturing policy for the part, and adding the digital supply item and the additive manufacturing policy to a blockchain ledger. A supplier can authorize a print job for the part, decrypt the digital supply item from the blockchain ledger, and print the part using the digital supply item on a three-dimensional printer, according to the additive manufacturing policy.

First claim

What is claimed is:

1 . A method, comprising:
generating a digital supply item associated with a product model for a part; encrypting the digital supply item; generating an additive manufacturing policy for the part; and adding the digital supply item and the additive manufacturing policy to a blockchain ledger, wherein a supplier can authorize a print job for the part, decrypt the digital supply item from the blockchain ledger, and print the part using the digital supply item on a three-dimensional printer, according to the additive manufacturing policy.

2 . The method according to claim 1 , further comprising generating a digital license for the supplier with the additive manufacturing policy and a serial number format for the part.

3 . The method according to claim 2 , further comprising adding the digital license to the blockchain ledger.

4 . The method according to claim 1 , further comprising adding a machine log obtained from the three-dimensional printer to the blockchain ledger.

5 . The method according to claim 1 , further comprising adding quality control results to the blockchain ledger, the quality control results being indicative of whether the part passed or failed quality control parameters of the additive manufacturing policy.

6 . The method according to claim 1 , further comprising generating an advanced shipment notice smart contract and transmitting the advanced shipment notice smart contract to another party on a blockchain network.

7 . The method according to claim 6 , further comprising sending a shipment that includes the part to the another party along with the advanced shipment notice smart contract.

8 . The method according to claim 7 , further comprising:
receiving the shipment; and executing the advanced shipment notice smart contract to accept or reject the part.

9 . The method according to claim 8 , wherein the advanced shipment notice smart contract further determines if the part passed or failed a quality control check.

10 . The method according to claim 9 , further comprising executing the advanced shipment notice smart contract to perform a digital supply item revocation check to determine when the digital supply item is active or revoked.

11 . The method according to claim 10 , further comprising executing the advanced shipment notice smart contract to determine if the part is a super part as identified by a part serial number, the super part falling within a specific and narrow tolerance compared to another part that is used along with the part in an assembly, the super part being identified by a custom filter in the advanced shipment notice smart contract.

12 . The method according to claim 11 , wherein the custom filter is included in a private smart contract that is maintained separately from the advanced shipment notice smart contract.

13 . A system, comprising:
a first node comprising a processor and memory, the processor executing instructions stored in the memory to:
generate a digital supply item associated with a product model for a part;
encrypt the digital supply item;
generate an additive manufacturing policy for the part; and
add the digital supply item and the additive manufacturing policy to a blockchain ledger;
a second node comprising a processor and memory, the processor executing instructions stored in the memory to:
authorize a print job for the part;
decrypt the digital supply item from the blockchain ledger;
cause the part to be printed using the digital supply item on a three-dimensional printer, according to the additive manufacturing policy;
generate an advanced shipment notice smart contract that includes at least quality control data for the part; and
execute the advanced shipment notice smart contract; and
a third node comprising a processor and memory, the processor executing instructions stored in the memory to execute the advanced shipment notice smart contract to determine when the part is a super part or when the part is matched with another part based on a dimensional measurement.

14 . The system according to claim 13 , wherein the first node is configured to generate a digital license for the second node with the additive manufacturing policy and a serial number for the part.

15 . The system according to claim 14 , wherein the first node is configured to add the digital license to the blockchain ledger.

16 . The system according to claim 13 , wherein the second node is configured to add a machine log obtained from the three-dimensional printer to the blockchain ledger.

17 . A method, comprising:
receiving an advanced shipment notice smart contract and a part, the advanced shipment notice smart contract being executed; executing the advanced shipment notice smart contract to determine when the part is a super part as identified by a part serial number in a digital supply item, or when specific dimensions of the part fall within a specific and narrower than a primary tolerance compared another part that is used along with the part in an assembly, the part being identified as the super part by a custom filter in the advanced shipment notice smart contract; and accepting or rejecting the part based on whether the part is the super part and/or based on quality control data included in the advanced shipment notice smart contract.

18 . The method according to claim 17 , wherein the custom filter is included in a private smart contract that is maintained separately from the advanced shipment notice smart contract.

19 . The method according to claim 17 , further comprising:
executing the advanced shipment notice smart contract to perform a digital supply item revocation check to determine when the digital supply item for the part is active or revoked; and adding a digital license to a blockchain ledger along with the digital supply item for the part.

20 . The method according to claim 17 , further comprising feeding the custom filter into another algorithm which, dictates a specific order for the part to be shipped in, or arranged by, or otherwise sorted.
