Additive manufacturing, also known as 3-D printing, is replacing conventional fabrication processes in critical areas ranging from aerospace components to medical implants. But because the process relies on software to control the 3-D printer, additive manufacturing could become a target for malicious attacks – as well as for unscrupulous operators who may cut corners. Researchers from the Georgia Institute of Technology and Rutgers University have developed a three-layer system to verify that components produced using additive manufacturing have not been compromised...
