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.
