Secure management of 3D print media

摘要

A system for printing 3D objects protects a 3D object file from being copied by separating the file into a series of instructions for printing the 3D object and sends those instructions piecemeal to a printing facility. The system enforces a methodology that forces the print facility to delete a previous set of instructions before the print facility can receive the next set of instructions to print a 3D object. By using such a system, the print facility never has the entire 3D print file in memory, preserving the rights of the creator of the 3D print file.

1. A method of printing a 3D object, comprising:
receiving a first subset of instructions for printing the 3D object; printing a first part the 3D object in accordance with the first subset of instructions; receiving a second subset of instructions; deleting the first subset of instructions; and printing a second part of the 3D object in accordance with the second subset of instructions, wherein the step of deleting the first subset of instructions occurs prior to the step of printing the 3D object in accordance with the second subset of instructions.
