Description
Bochuan Liu, Paula Wilson, Mark Williams, and Gregory Gibbons present an anti counterfeit method for 3D printed parts in a 2026 paper. Printing turns digital files straight into objects, which makes supply chains easy targets for fakes. Their method hides tiny marker particles, called taggants, at random spots inside a part during a light based printing process.
The random pattern acts like a fingerprint that cannot be copied. A digital hash is built from X-ray scans of the pattern, giving a double lock of physical and digital proof. The markers had no clear effect on heat traits and cut tensile strength only slightly. The authors say the scheme resists replication well.
