Abstract: One embodiment of the invention may relate to a print surface for a three-dimensional object printer. The print surface may comprise an elastic first layer, a binding layer for securing the printing surface to the three-dimensional object printer; and an adhesive layer for adhering the first layer to the binding layer. Three-dimensional objects are printed onto the first layer by controlled extrusion of molten material. Printed objects can be obtained by decoupling the binding layer from the three-dimensional object printer and detaching the object from the first layer by applying bending moments.

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.
