HAMMER – Hub for Additive Manufacturing Materials Engineering Research and

About Us

HAMMER (Hub for Additive Manufacturing, Materials Engineering and Research) is a network of expertise and instruments established between the Gran Sasso National Laboratories (LNGS) and the Rome Section of the INFN, equipped for R&D, prototyping, and characterization of metallic and polymeric materials processable through various additive manufacturing techniques, ranging from innovative metal alloys to nanocomposite materials.

Centre of expertise for R&D on innovative materials and additive manufacturing of metals parts by multilaser PBF-LB systems and polymer parts by DLP and FDM technologies, with capabilities in metal ultrasonic atomization, surface and heat treatments, low and high temperature material testing, metallography and industrial x-ray computed tomography.

Centre of expertise for R&D on innovative nanotechnology-enabled materials for metal additive manufacturing. Part of the HAMMER network, it collaborates with Sapienza University of Rome laboratories and is equipped for nanomaterials-based powder modification, powder analysis, and industrial-grade polymer AM using FDM and PolyJet technologies.
