Francisca G. Caballero, Research Professor at the Spanish National Centre for Metallurgical Research (CENIM-CSIC) and NewAIMS partner, participated in the 2nd edition of the Metal AMS International Symposium on Metal Additive Manufacturing, held on March 20th-21st, 2024, at the facilities of the French Technical Centre for Mechanical Industries (CETIM) in Senlis (France).

On March 20th, she delivered a plenary talk entitled “Revealing the complexity of 3D printed microstructures of steels”, which contained a general approach to the NewAIMS project and an illustration of some typical microstructures produced by laser powder bed fusion (LPBF) in commonly used steels.

The main objective of the presentation was to unveil how chemical and microstructural heterogeneity at the micro- and nano-scale of additively manufactured steels affect the microstructural evolution during printing and post heat-treatments.

In this sense, advanced microstructural characterization, including spatially resolved composition investigations, reveal the micro- and nanostructures of apparently well-known materials after synthesizing and processing them via novel additive manufacturing methods.

Metal AMS is the first French scientific symposium fully dedicated to metal additive manufacturing technologies. It is organized by the French metal additive manufacturing community in collaboration with major R&D players from around the world, addressing every step of the AM value chain.

The selected topics discussed in the conference include design, materials, simulation, direct and sintered-base processes or monitoring and control/qualification challenges.
