Fraunhofer launches “SLM in Green” project for 3D printed copper

Known for its malleability and typically ductile composition, copper is a seemingly ideal material for metal 3D printers. In addition, the metal exhibits a level of thermal conductivity second only to silver, and high electrical conductivity making it desirable for industrial applications. It is this conductivity however that makes the metal notoriously difficult to work with inside a 3D printer. The metal is simply too good at transferring the heat applied by a laser beam. “Depending on surface properties,” explains Daniel Heussen, research fellow in the Rapid Manufacturing group at Fraunhofer ILT, “pure copper reflects up to 90 percent […]
