Copper is a metal known for its fantastic thermal and electrical conductivity. Ideal applications for 3D printing in copper include induction coils, heat exchangers and electrical wiring.
Copper is a metal material very popular for its great thermal and electrical conductivity, and high ductility. Ironically, these characteristics are also what made it impossible to be 3D printed until 2018. For instance, its highly conductive properties caused the heat from electric beams to be reflected. Material manufacturers had to develop new techniques to make 3D printing with this metal alloy possible.
These new techniques have optimized the material and existing processes in a way that highly conductive 3d printed copper parts can now be produced in a cost-efficient manner. These parts exhibit high stiffness, low magnetic permeability and high elongation at break. One of its main physical characteristics is the reddish color that gets a greenish hue due to oxidation.
One of the advantages of 3D printing in copper is the increase in performance caused by the design freedom that only additive manufacturing can offer. Some common applications for copper parts are heat exchangers, induction coils heat pipes and hair pin stator.
