SPATIOTEMPORAL G-CODE MODELING FOR ADDITIVE MANUFACTURING SECURITY
This project focuses on the security of 3D printers. Cyberattacks on 3D printers function by making malicious modifications to the numerical control code (G-code) used to direct the printer. These manipulations change the manufacturing parameters used to generate a particular part so that the part no longer meets design criteria. Crudely executed attacks result in parts that are unusable and represent unnecessary waste. Although such attacks are unwelcome, more serious results may be experienced in connection with a more sophisticated attack. This research addresses the development, simulation, and study of concealed defects and their effects - focusing on filament-kinetic and thermodynamic defects - and the detection of such concealed defects. This analysis advances the understanding of which types of concealed defects cause the most significant effect, as well as the ability to detect attacks as they occur.
