See No Evil, Hear No Evil, Feel No Evil
summary
Claims a firmware- and PC-independent verification scheme that combines Shazam-style peak constellations from microphone recordings, real-time spatial tracking via a potentiometer + gyroscope on the nozzle, and post-production material checks using Raman spectroscopy and CT scans with embedded markers like stainless-steel filament markers or gold nanorods. Evaluated on three 3D printers and one CNC, the system detects malicious or erroneous prints in real time with reported 100% accuracy, flags a faulty tibial knee prosthesis within 4–6 minutes, and supports stopping the job and CT confirmation.
