                    The Invention
                    
                        UW-Madison researchers have developed a process for producing core-shell metal matrix nanocomposite wire for directed energy deposition (DED) additive manufacturing. The procedure involves first producing powder with dispersed nanoparticles using ball milling, then adding the powder to a U-shaped metallic foil. The metallic foil is then closed and reduced to a final diameter using rolling techniques. This method avoids issues associated with other techniques such as clustering and flying powders. Nanoparticles are uniformly distributed in the core of the core-shell MMNC wire, and the volume fraction of nanoparticles in the wire can be arbitrarily designed. The core-shell MMNC wire is safe and effective for large-scale additive manufacturing and welding of MMNCs.
