3D Printing is a business that earns $ 4 billion a year. 3D printing is really used in everything from cars to bridges, art to food, and calls into question the validity of many centuries of production practices.
Indeed, the FAA recently certified the first 3D-printed part for a commercial jet engine. It seems that we are already assigning our lives to 3D-printed equipment on an almost daily basis.
However, like the electronics and computer industries, this new technology is beginning to be threatened by some of the dangers of cyberspace.
A team of cybersecurity engineers at the NYU Tandon School of Engineering published a study in The Journal of the Minerals, Metals & Materials Society, which reveals foundings and, fortunately, offer some initial recommendations to combat the issue.
The XNUMXD printers, as you know without a doubt, create from a CAD file sent by a designer. The construction software then analyzes the design, slices it and places the printer head so that the printer can apply the materials in extremely thin layers.
"These are some potential outbreaks of attacks that could have a devastating effect on end users and many economic consequences in the form of lawsuits, "said Nikhil Gupta. As the orientation of the head or his product when printed it could cause up to 25% variation in its inherent power, which means that anyone wishing to cause problems in the final product could do so with almost no detection.
The researchers found that when they introduced defects below the millimeter between the printed layers, the defects were not detectable by common industrial monitoring techniques such as ultrasound imaging and, over time, the materials weakened due to fatigue, heat, light and humidity, and became more vulnerable to these small defects.
The simplest thing for an intruder is to invade any XNUMXD printer connected to the Internet and import internally defects at the printing stage that no one will discover until the section fails to be created.
Zeltmann, lead author of the study, said that to protect themselves from these risks, companies should not keep their XNUMXD printers connected on the Internet.
