Founded at the end of 2022, S.A.M (Signature & Authentification des Matériaux) is a young French company born of the encounter between materials science and digital technology. Established by two researchers, S.A.M’s mission is to fight counterfeiting and protect sensitive data through innovative technology based on 3D printing.
At the heart of this solution are objects called tokens: genuine 3D-printed physical keys, capable of holding confidential information such as proof of ownership, serial numbers or secure access. This system enables everyone to produce their own protection, simply, autonomously and completely offline. We spoke to Cédric Prins, President of S.A.M, to find out more.

3DN: Could you introduce the company and your link with additive manufacturing?
S.A.M (Signature & Authentification des Matériaux) was created at the end of 2022, based on the research work of co-founders Samuel Kenzari (CNRS) and Sylvain Lefebvre (INRIA). Both have been developing new materials and shaping algorithms for various additive technologies for many years in their respective laboratories (Institut Jean Lamour and Loria). As a result, the company offers a unique solution, the result of 8 years of R&D, combining materials and digital sciences, not only to combat counterfeiting, but also to secure sensitive data without cyber risks.
