Abstract: In an example, a method is described. The method includes determining a cryptographically-derived content for a marking based on a blockchain ledger. The blockchain ledger comprises a record authorizing a manufacturing apparatus to create an object. The method further includes determining object creation instructions to create a modified version of the object comprising the marking. The manufacturing apparatus may create the modified version of the object according to the determined object creation instructions.

Abstract: A method comprises: receiving, at a secondary printer module, an attestation challenge generated by a primary printer module; deriving, from a set of executable instructions encoded on a non-transitory machine-readable storage medium of the secondary printer module, a private key: generating, from the attestation challenge and the private key, a response to the attestation challenge; and communicating the response to the primary printer module.

Abstract: An example method for use in additive manufacturing comprises operating, by a processor, on object model data, the object model data describing an object to be generated in an additive manufacturing process. The example method comprises determining, by a processor, based on the object model data, whether a portion of the object to be generated is identified as an object of interest. In response to a determination that a portion of the object to be generated is identified as an object of interest, then the method comprises determining, by a processor, whether a policy-based action is associated with the object of interest. In response to a determination that a policy-based action is associated with the object of interest, then the method comprises executing, by a processor, the policy-based action, and generating, by a processor, the object according to the policy-based action.

Abstract: In an example, a method includes acquiring, at a processor, object generation source data representing a three-dimensional object to be generated in additive manufacturing. A dataset which is representative of an aspect of the three-dimensional object may be determined from the object generation source data. Digital security may be applied to the object generation source data and the dataset. The digital security applied to the object generation source data may be different from that which is applied to the dataset.

Abstract: A system for protecting a printing capability may include sprinting consumable, and a data element associated with the printing consumable, the data element defining an assigned association between the printing consumable and a printing capability. Also, a method of protecting a printing capability via consumables may include assigning an association between a printing consumable and a printing capability, the association protecting the printing capability based on availability of the printing consumable, determining whether the printing consumable is installed in a 3D printing device to allow for the execution of the printing capability in forming a 3D object, and in response to a determination that the printing consumable is installed in the 3D printing device to allow for the execution of the printing capability, permitting the printing of the 3D object using the printing capability and consuming of the printing consumable.
