Using additive manufacturing to detect counterfeit parts — ScienceDaily

Making sure produced merchandise and elements have not been copied and replaced illegally by counterfeited goods is a substantial-precedence problem of the production and defense industries in the U.S. and around the planet.

A possible solution would keep broad-achieving impacts and implications in several regions ranging from boosting biomedical implants to protecting countrywide defense assets.

Texas A&M University scientists have designed a technique of imprinting a hidden magnetic tag, encoded with authentication data, within just created hardware for the duration of the section fabrication process. The innovative procedure retains the possible to expose counterfeit goods additional effortlessly by replacing actual physical tags — these as barcodes or speedy reaction (QR) codes — with these concealed magnetic tags, which provide as long-lasting and special identifiers.

The challenge, titled “Embedded Facts in Additively Made Metals by using Composition Gradients for Anti-Counterfeiting and Offer Chain Traceability,” is a faculty companion job supported by the SecureAmerica Institute. It consists of researchers from the Division of Resources Science and Engineering and the J. Mike Walker ’66 Office of Mechanical Engineering at Texas A&M. The team just lately published its investigate in the journal Additive Production.

The college investigators on the task involve Ibrahim Karaman, Chevron Professor I and department head of the products science and engineering division Raymundo Arroyave, professor of products science and engineering and Segers Household Dean’s Excellence Professor and Richard Malak, associate professor of mechanical engineering and Gulf Oil/Thomas A. Dietz Vocation Progress Professor. In addition to the school, Daniel Salas Mula, a researcher with the Texas A&M Engineering Experiment Station, and doctoral pupil Deniz Ebeperi — each customers of Karaman’s study group — have labored on the undertaking. The crew has also collaborated with Jitesh Panchal, professor of mechanical engineering at Purdue College.

Ensuring safety and reliable authentication in production is a important nationwide issue, with the U.S. investing billions of bucks in production. Devoid of such a technique quickly readily available, it can be almost unachievable to differentiate an genuine element or element from its counterfeit copy.”The situation is that when I arrive up with an concept, gadget or portion, it is quite uncomplicated for many others to duplicate and even fabricate it significantly additional cheaply — though possibly at a decrease excellent,” Karaman mentioned. “In some cases they even put the same brand title, so how do you make absolutely sure that product just isn’t yours? [The embedded magnetic tag] provides us an possibility and a new resource to make absolutely sure that we can secure our defense and production industries.”

The crew is employing metal additive production procedures to achieve its goal of properly embedding readable magnetic tags into metallic parts without the need of compromising on efficiency or longevity. Researchers used 3D printing to embed these magnetic tags underneath the surface area into nonmagnetic steel components.

Other apps for this process contain traceability, excellent management and additional, mostly based on the industry in which it is used.

The moment embedded into a nonmagnetic merchandise, the magnetic tag is readable utilizing a magnetic sensor device — these kinds of as a smartphone — by scanning around the proper locale on the product or service, letting the designated info to be accessed by the consumer.

While other approaches exist for imprinting info, they largely have to have complex and highly-priced devices that introduces a barrier to actual-world implementation.

“Unique methods have been made use of to consider to locally modify the qualities of the metals during the production course of action to be equipped to codify data within the section,” stated Salas Mula. “This is the initial time that magnetic homes of the product are remaining made use of in this way to introduce data in a nonmagnetic element, precisely for the 3D printing of metals.”

Ebeperi explained that to map the magnetic looking through of the component, the group developed a personalized three-axis magnetic sensor capable of mapping the floor and revealing the regions wherever the embedded magnetic tag was available.

Even though the program is much more safe than a physical tag or code located on the exterior of an merchandise, the team is continue to doing work to make improvements to the complexity of the method’s stability.

As the challenge continues, Karaman claimed the subsequent methods consist of creating a extra protected system of looking at the information and facts, perhaps via the implementation of a actual physical “twin-authentication” requiring the person to apply a certain cure or stimulus to unlock entry to the magnetic tag.
