3D-printing with copper

Since 2018, you can obtain 3D-printed copper components directly from digital data.

Copper and copper alloys are particularly suitable for application and work areas in which high thermal and/or electrical conductivity is required. Copper alloy hardens thermally. Thanks to the forward-thinking 3D-printing process SLM (selective laser melting; 3D-printing of metal via laser melting), complex geometries with internal cavities or channel systems can be implemented in a single operation.

At FKM, you can choose between pure copper CuCP, the copper alloy CuCrZr and the beryllium-free copper alloy CuNi2SiCr for your 3D printing with copper.

Applications and properties

As is generally typical for the SLM process, complicated geometries that cannot be realised with conventional processes are also possible with the copper variants available from FKM. In FKM’s SLM machinery, components from pieces up to a size of 250 x 250 x 310 mm are possible for 3D-printing with copper.
