Components Made From Copper Powder Open Up New Opportunities
Up to now it was not possible to use Selective Laser Melting (SLM) on copper alloys. Now, however, research scientists at the Fraunhofer Institute for Laser Technology ILT have solved the technical problems that prevented this by enhancing the technique. The new method opens up new possibilities, for instance in plastics processing.
