When we talk about 3D printing and security concerns, one of the first issues that comes up is that of counterfeit 3D printed parts. Several companies have experimented with anti-counterfeiting measures like embedded identification tags, but a group of researchers at NYU Tandon School of Engineering have come up with a method that's even trickier. In a new study, the researchers explain how flaws can be introduced into the design files of 3D printed parts to foil thieves. The flaws, which are hidden in the CAD files, can be made to disappear when the part is 3D printed under very specific conditions. Without knowing what those conditions are, a counterfeiter would inadvertently print a flawed, lower-quality part. Read more at 3DPrint.com: http://3dprint.com/175552/nyu-resear...terfeit-parts/
