Abstract: 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.

Abstract: A contemplated system analyzes files used to create 3D objects by first virtually constructing the 3D object, and then by examining the virtual construct in a variety of different ways to determine if the 3D object has protected content. The system could examine the virtualized object from a variety of different angles, read characters embossed or imprinted upon the 3D object, and could even play virtualized records and other virtualized video/audio tools to determine if the 3D object has protected content. If the system rules that the 3D object has a high probability of having protected content, an alert is sent to an appropriate authority.
