The m2AM-SLMC project presents a novel approach for the Additive Manufacturing (AM) of dual-functional Si/MXene core-shell micropillars through a single-run laser-based powder bed fusion (L-PBF) process. This innovative method enables the in situ formation of high-performance, binder-free energy storage architectures by combining electroactive silicon nanostructures with laser-exfoliated
Tin+1Cn MXene layers. The resulting 3D-printed porous structures exhibit exceptional charge-discharge stability, energy density, and conductivity, addressing the urgent need for lightweight, multifunctional energy solutions in both terrestrial and space environments. The project is structured around three key objectives: 1) the mechanochemical synthesis of optimized powder feedstocks, 2) the L-PBF fabrication of TiC micropillar cores, and 3) the stabilization of MXene shells through Si nanostructure intercalation. This process allows fine control over micro-/nanostructure uniformity, interfacial chemistry, and electrochemical performance without the use of hazardous chemicals or post-processing steps.
Aligned with ESA’s Clean Space and Advanced Manufacturing strategies, m2AM-SLMC promotes sustainability, on-demand production, and compatibility with in-orbit and off-Earth manufacturing scenarios. With potential applications in satellites, lunar infrastructure, and deep-space systems, the project contributes directly to ESA’s 2040 strategic vision and Europe’s technological sovereignty. Providing a rapid solution promising safer, greener, and high-performance energy conversion and storage systems, m2AM-SLMC also holds commercial promise across automotive, aerospace, and grid storage sectors, supporting global clean energy transitions and the UN Sustainable Development Goals 7, 11, and 13.
