3D printing with Copper

3D printing based in copper is done by Selective Laser Melting (SLM). Copper is a complex material to procces by this technology due to its high reflectivity. This characteristic makes that part of the laser energy needed for the piece manufacture is absorbed by the powder. To manufacture pieces using a 90% purity copper powder is it neccessary to use an equipment with specialised laser and high knowledge of this technology and the material.


3D printing process with Copper

To 3D print with copper, high expertise in SLM technology and specific laser conditions are necessary to effectively melt the powder. Factors such as laser power, optimal part design and substrate positioning will be crucial for higher part yield.

Technical specifications of Copper

  • Cu
  • Excellent electrical conductivity 01.
  • High thermal conductivity 02.
  • Corrosion resistance 03.

The high thermal and electrical conductivities of copper, combined with optimized designs, make it possible to optimize the designs to reduce energy losses of conductive components. It has high corrosion resistance and mechanical properties.

Additive manufacturing of heat exchangers with copper

Through the technology we have in Addimen, we can manufacture pure copper heat exchangers by SLM. Thanks to the combination of this material with additive manufacturing, it is possible to obtain inductors or heat exchangers with optimal geometries for each process that would not be possible through conventional machining techniques, thus improving the energy exchange with almost no losses.

If you do not have the file, send us the item and we will create the CAD file.
If you need a design from scratch, our designers will gladly prepare a quote for you.

3D Printing

We will create the process file adapted to the technology and materials that will be used to produce your item.
We prepare and condition the printer to guarantee optimum quality.

Cleaning and post processing

This step is key when meeting your requirements, and it is one that we are highly specialised in.
The removal of the printing support structures, heat treatments, and surface finishes (blasting, polishing, tooling) are some of the most common post processes.
