Abstract:

A system for secure 3D printing, the system comprising a server computer configured to transmit cryptographic key upon initiation of a print phase, each of the cryptographic keys being unique to individual 3-dimensional objects and unique to individual 3D printers. A 3D printer is configured to print 3-dimensional objects. The 3D printer comprises a network interface, print actuation devices, a processor, and a memory device coupled to the 3D printer containing encrypted printing instructions and computer code for receiving a plurality of cryptographic keys unique to the 3D printer and pertaining to a particular 3-dimensional object, decrypting encrypted printing instructions for printing the particular 3-dimensional object, and performing the decrypted printing instructions to print the particular 3-dimensional object.
