With the potential to shakeup the design of everything from air planes to refrigerators, Dr Tim Huber and Professor Conan Fee have developed a new metal 3D printing methodology for making high-performance heat exchangers.
Elaborating upon traditional cylinder and square shapes, the heat exchangers built by Huber and Fee bring new, complex designs to the field that are impossible with other means of manufacturing.

3D printing can take the heat
Heat exchangers have been re-imagined by 3D printing in a number of cross-industry applications.
Air Liquide used additive manufacturing to make an award-winning milli-structured heat exchanger reactor that can be used for hydrogen production purposes.
In a paper presented at the 8th International Conference on Applied Energy, researchers used PolyJet 3D printing to make more environmentally friendly stacks for refrigerators.
