Researchers find security vulnerabilities in 3D-printing process – Technical.ly Brooklyn

A team of researchers at NYU Tandonpublished a paper last week, finding several types of future security vulnerabilities in the 3D printing system. In particular, the researchers focutilized on the insertion of satisfactory defects, and the orientation of the printing device head.
“Recently, the FAA [Federal Aviation Administration] approved the initially 3D-printed part, a fuel nozzle, for use in aircraft engines,” Nikhil Gupta, an associate professor of mechanical engineering at Tandon, and a coauthor of the paper, said in an interview. “Examples of most other industrial and medical applications are now on the market in which 3D-printed parts are put into service. In these cases, attention to security aspects is necessary.”
One method researchers utilized was to manufacture minor changes the CAD files which printing devices read and print. They added microscopic defects into the product, which may be undetectable by normal high end control methods, but which, over time may seriously compromise the durablity of the product. If you are dealing with jet planes, which may be an issue.

This is significant for us for the reason Brooklyn is perhaps the center of 3D printing in the world. According to a separate report of earlier this week, New York “continues its reign as the 3D printing capital of the world.” According to its data, accessed in mid-July, New York is home to 3,739 manufacturers and 516 3D printing devices, far ahead of second-place Los Angeles (which has 2,557 manufacturers and 410 printing devices), and the big New York players, which include MakerBot and Voodoo Manufacturing, are both based here in Kings County.
“If a printing device is directly hacked and the changes are turn it intod on-the-go to turn it into a defect (such as ordering the printing device to skip depositing the material or depositing it at a low temperature so which it does not fuse with the other layer),” Gupta said, “then the defects may go undetected as a lot of parts are created over several hours of printing time. Many printing devices are always connected to internet to queue the print jobs remotely or to diagnose problems.”

So can this take down the industry? Is it only a speed bump? Couldn’t traditional making be hacked, too?
Well, in traditional making, parts are typically turn it intod by machines not connected to the internet and in addition live, human individuals. The lens through which to view 3D printing is not making, but pretty software.
“The trend appears to be which new security approaches are created continuously and a few of them are breached, and the industry moves on to the future new security technology,” Gupta explained. “The same trend may in addition be applicable to security of 3D printing for the reason it is usually protected under the same network which is hosting other systems of a company. We want to bring focus specifically to the security of 3D printing for the reason if a part create is stolen, it cannot be changed or replaced with a new create. That intellectual property is lost forever.”-30-
