Claim:
1. A method for identifying a printing source of a 3D printed object, comprising: analyzing a 3D object print file for printing a 3D printed object to identify one or more candidate regions within a 3D printed object for insertion of printer identification information, wherein the one or more candidate regions are identified as being regions that do not affect the structural integrity of the 3D printed object so that the printing of the printer identification information does not degrade object performance; inserting computer-executable code into the 3D object print file for printing the printer identification information in the one or more candidate regions; and printing the 3D object with the printer identification information embedded in the one or more candidate regions; wherein the printer identification information is embedded by omitting one or more voxels within the 3D printed object to form one or more structures each comprising one or more voids created by voxel omission within the 3D printed object.
