3D printing in copper

3D printing process 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.

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.

Cu99.9

Using the technology we have at Addimen, we can manufacture heat exchangers in pure CU 99.9 copper using SLM. By combining 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 using conventional machining techniques, thus improving energy exchange with virtually no losses.

GrCop42

Additive manufacturing of GrCop42 allows us to produce watertight inductors with geometries optimised to fit the target part, significantly improving heat transfer. In addition, it enables the manufacture of complex designs in a single piece, eliminating the need for welds. These welds, common in traditional processes, are often weak points where failures originate. By avoiding them, reliability is increased and the service life of the inductor is extended.

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.

Copper 3D printing process

Step 1: 3D file

Send us your 3D file ready for printing. If you do not have the file, send us the piece and we will generate the CAD file.

If you need a design from scratch, our designers will be happy to make proposals.

Step 2: 3D printing

We generate the process file adapted to the technology and material to be used in the manufacture of your part.

We prepare and condition the printer to ensure optimal quality.

Step 3: Cleaning and post-processing

This step is key to meeting your requirements and one in which we are highly specialised.

The removal of printing supports, heat treatments and surface finishing (blasting, polishing, machining) are the most common post-processing steps.

Applications of 3D printed copper

Generally most of the copper uses are for pieces that requires high thermal or electrical conductivity. Moreover, due to its ductility, mechanical resistance and good performance to corrosion, it is the ideal material for electrical applications in energy-efficent equipment.
