    3D Printing in Practice

    More Energy Efficiency With Additive Manufacturing
    Cooling Elements and Heat Exchangers From a Metal 3D Printer

For many applications, sophisticated cooling technology is important. For gaming PCs, data centers, automobiles, LED modules, the chemical industry and many more; wherever you need to dissipate heat, heat exchangers and cooling elements are essential. Their size is often a challenge. For example, hand-held electronic devices need to house increasingly powerful technology that requires cooling. In addition, they need to integrate new functionality quickly, meaning that the heat problem needs to be solved again and again. This quickly pushes conventional production processes to their limits.

However, industrial 3D printing is different. It enables very small and complex parts to be made from alloys with favorable thermal conduction properties. As a result, heat management can be performed in a very small space. For example, CPU coolers with liquid cooling but no weak points susceptible to leakage can be mass-produced in a single piece.

Additive manufacturing makes it possible to efficiently manufacture especially compact heat transport solutions that set new standards in terms of effectiveness, reliability and space usage.


Our Portfolio for the Additive Manufacturing of Heat Exchangers & Cooling Elements High-Quality Systems and Materials

Our systems allow you to manufacture heat exchangers from high-quality thermally conductive alloys with a number of advantageous properties using 3D CAD data. Flexible design, optimized heat transfer properties and reduced build size are just a few examples.

Metal 3D printing is an exciting and disruptive technology. But initially I was skeptical whether its advantages would extend to meet our own requirements. Three years on, it has given us solutions for many projects that would not have been possible otherwise.

Advantages of Additive Manufacturing for Heat Exchangers


Lightweight and space-efficient

Direct Metal Laser Solidification (DMLS) makes it possible to manufacture heat exchangers that are lighter and require less space, featuring complex geometries and maximal surface area.


Highly complex cooling channels

When it comes to making internal cooling channels with complex shapes, additive manufacturing should be your first choice.


Parts without joints

The 3D printing process creates parts in a single piece. This avoids any assemblies with welded seams, eliminating the risk of leakage.  


Excellent thermal conductivity

A wide range of materials with excellent thermal conductivity properties are available for additive manufacturing. The shape freedom also enables heat transfer paths to be minimized. 


Reach the market quickly

Additive manufacturing accelerates the path from prototype through pilot series production to series production, speeding up market entry.
