Abstract
A starter may be used to facilitate fabrication of objects from an automated fabrication device, such as a 3-D printer. In one implementation, the starter may include a starter memory storing encrypted fabrication instructions and feedstock material that encodes the cryptographic key suitable for decrypting the encrypted fabrication instructions. The cryptographic key is accessed and used to generate decrypted fabrication instructions from the encrypted fabrication instructions. Subsequent fabrication consumes or changes the feedstock material such that the data stored thereon is destroyed or otherwise inaccessible.
Claims20
A system comprising:
- a starter comprising:
- a build platform;
- a non-transitory computer-readable storage medium (CRSM) storing encrypted fabrication instructions for automated fabrication of an object, wherein the encrypted fabrication instructions are encrypted using a cryptographic key;
- and
- feedstock material for fabrication of the object, wherein the feedstock material stores the cryptographic key;
- an additive three-dimensional printer comprising:
- a mount configured to retain the build platform during operation;
- an extruder configured to use the feedstock material to fabricate the object;
- and
- a sensor configured to retrieve the cryptographic key stored in the feedstock material prior to extrusion by the extruder;
- and
- a device to:
- access the encrypted fabrication instructions stored by the CRSM of the starter;
- retrieve the cryptographic key;
- decrypt the encrypted fabrication instructions to produce decrypted fabrication instructions;
- and
- direct, using the decrypted fabrication instructions, the extruder to fabricate the object on the build platform from the feedstock material, wherein use of the feedstock material destroys the cryptographic key stored therein.
A system comprising:
- a starter, the starter comprising:
- a memory storing computer-executable encrypted instructions for fabricating at least a portion of an object using an automated fabrication device;
- and
- feedstock material that stores encoded data that is used to decrypt encrypted computer-executable instructions, and wherein the feedstock material is used by the automated fabrication device to fabricate the at least portion of the object.
A device comprising:
- a memory storing encrypted fabrication instructions for automated fabrication of an object, wherein the encrypted fabrication instructions are encrypted using a cryptographic key;
- an automated fabrication device, the automated fabrication device comprising:
- a fabrication assembly to use feedstock material to fabricate at least a portion of the object;
- a sensor to read encoded data stored by the feedstock material;
- and
- a hardware processor to:
- access the cryptographic key stored on the feedstock material;
- access the encrypted fabrication instructions;
- generate decrypted fabrication instructions from the encrypted fabrication instructions using the cryptographic key;
- and
- fabricate, using the automated fabrication device, at least a portion of a three-dimensional object using the decrypted fabrication instructions.
