3D prints have unique "fingerprints" that allow the identification of individual machines, even those of the same model. University of Illinois researchers, led by Bill King, created an AI system ...

3D printers leave hidden 'fingerprints' that reveal part origins Date: May 22, 2025 ... and each machine leaves a unique fingerprint that the AI model can trace back to the machine," King said.

Those thermodynamic properties can be used to identify the specific extruder and, thus, the model of 3D printer, as uniquely as a human fingerprint, or, as Jin calls it, a "ThermoTag." ...
