Researchers Design Methods to Embed Flaws in 3D Printed Objects to Prevent Hacking

(Electronics360) Researchers at NYU Tandon School of Engineering have discovered a way for manufacturers to protect their designs by deliberately embedding hidden flaws in CAD files to thwart this property theft. The team developed security features that range from the induction of voids in a part that is supposed to be solid, to features that make the part print in sections that break apart easily.
“The range of security feature designs demonstrated in this work can provide great flexibility to application engineers in terms of how to disguise these flaws easily in a complex shaped part,” says Fei Chen, a doctoral student at NYU Tandon. “Most industrial components manufactured using 3D printing have complex designs to justify the use of 3D printing, which further helps in embedding these features without detection.”
