3D printers can churn out toys, clothing and even food. But the technology also shows potential for use in industrial sabotage, researchers warn.

Imagine a car maker using 3D printers to manufacture components, only to have the parts contain defects that are undetectable until it’s too late.

A hacker with access to the 3D printers could make that happen, a team of researchers wrote in a recent paper. This could result in a “devastating impact” for users and lead to product recalls and lawsuits, said New York University professor Nikhil Gupta, the lead author of the paper.
