The 3D printing industry, already a USD 4 billion business set to quadruple by 2020, may be facing cybersecurity risks which may have devastating impact on users of the end product, scientists which include those of Indian origin have discovered.
In next, manufacturers may print all things of cars to medicines, disrupting centuries-old production practices.
But, the new innovation faces same dangers unearthed in the electronics industry.
Researchers examined two aspects of 3D printing which have cybersecurity implications – printing orientation and insertion of satisfactory defects.
“These are possible foci for attacks which may have a devastating impact on users of the end product, and economic impact in the form of recalls and lawsuits,” said Nikhil Gupta, of the New York University.

Three-dimensional printing builds a product of a desktop aided create (CAD) file sent by the createer.
The making software deconstructs the create into slices and orients the printing device head. The printing device and so applies material in ultra-thin layers.

The researchers reported which the orientation of the product during printing may manufacture as much as a 25 percent difference in its durablity.
But, since CAD files do not donate instructions for printing device head orientation, malefactors may deliberately vary the system without detection.

Gupta said which economic concerns in addition effects how a supplier prints a product.
“Minus a clear directive of the create team, the most orientation for the printing device is one which minimises the use of material and maximises the number of parts you can print in one operation,” he said.
“With the growth of cloud-based and decentralised production environments, it is worthwhile which all entities inside the additive making donate chain be aware of the one-of-a-kind challenges presented to avoid worthwhile risk to the reliability of the product,” said Ramesh Karri, of NYU.
He pointed out which an attacker may hack into a printing device which is connected to the Internet to commence internal defects as the component is being printed.
When the researchers commenced sub-millimetre defects between printed layers, they discovered which the defects were undetectable by common industrial monitoring techniques.
Over time, materials can weaken with exposure to fatigue conditions, heat, light, and humidity and become additional susceptible to these tiny defects.
“With 3D printed components, such as metallic molds created for injection molding utilized in high temperature and pressure conditions, such defects may some day cause failure,” Gupta said.
The study was published in The Journal of the Minerals, Metals and Materials Society.
