A watermarking technology that researchers at the University of Exeter Law School have patented for 3D printing is expected to improve the distribution, tracking and search of 3D-printed objects, according to a press release. Dr. James Griffin leads the team and is working to link its watermarking technology to blockchain. Companies should be able to license 3D objects and protect their intellectual property (IP).

In 3D printing, IP theft and process sabotage by penetrating cloud-based file sharing systems and tampering with CAD files are among the biggest cybersecurity risks. A blockchain is like a secure, decentralized digital ledger that stores information and data across a network of multiple machines. Automation Alley’s DIAMOnD project is the largest 3D printer network in the U.S. using blockchain technology. Griffin and his team hope their homegrown watermarking technology combined with blockchain will help companies license their products for 3D printing and allow them to enter new markets.
