Dragon Copper is a\u202fnanocomposite material.\u202fInnovative for 3D printing, it consists of a copper matrix in which carbon nanotubes are dispersed. The addition of carbon nanotubes has the dual effect of improving the electrical and thermal conduction properties of metallic copper, while also significantly increasing the mechanical strength. <\/p>\n

How does it work?<\/span><\/h3>\n

The production process is based on two steps:<\/p>\n

    \n
  1. \n
      \n
    1. \n
        \n
      1. 1) An innovative method of mixing nanotubes with pure copper powder which allows for a fine and uniform dispersion;<\/li>\n
      2. 2) The production of nanocomposite artefacts by additive manufacturing, in particular Laser Bed Powder Fusion.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

        The combination of the material with additive manufacturing makes it easy to produce complex-shaped objects with advanced properties; for example, the addition of 0.1% by weight of nanotubes makes it possible to increase the stress at break by more than\u202f170%, paving the way for the use of this material for components that have both thermal and structural functions.<\/p>\n
