3D printed Conflux oil cooler completes full-distance endurance race on Multimatic-engineered car

Melbourne, Australia – 27 February 2026 – A 3D-printed, configurable transmission oil cooler from Conflux Technology has successfully completed a full-distance endurance race on a Multimatic-engineered car, underlining Conflux’s credentials as a cooling supplier to top-level international motorsport.

Using Conflux’s configurable core platform, the transmission cooler was adapted to the programme’s specific boundary conditions and produced in just two weeks using metal additive manufacturing. Multimatic Motorsports selected and integrated the unit for an endurance application, gaining a race-proven solution without the cost and delay of a clean-sheet design.

The Conflux oil cooler used engine coolant to manage gearbox oil temperatures within a shared water circuit. In this application, it delivered approximately 20% higher heat rejection than the incumbent solution within the same packaging envelope, providing additional thermal headroom without extra space, weight or aero penalty.

“Endurance racing is the ultimate test for any cooling system,” said Glenn Rees, Principal Engineer at Conflux Technology. “We’ve shown that our configurable, 3D-printed technology can move from design to race car in weeks, deliver significantly improved performance, and still be trusted to reach the finish line in some of the world’s toughest races.”

The 3D-printed core incorporates highly optimised internal channels to increase heat transfer while controlling pressure drop within a compact, lightweight envelope. Conflux’s configurable design platform allows engineers to rapidly tune geometry for different gearboxes, layouts and duty cycles, reducing non-recurring engineering costs and shortening programmes’ time-to-track, without compromising durability or consistency over long stints.

“At Multimatic we look for partners who can combine innovation with robust delivery,” said Julian Sole, Design Manager at Multimatic Motorsports. “The Conflux oil cooler, built from their configurable design and packaged efficiently in a very tight space, delivered the reliability we required over a full endurance race distance.”

The successful endurance outing adds to Conflux’s growing body of work supplying 3D-printed heat exchangers into motorsport and high-performance automotive programmes. The same configurable oil cooler architecture is now available to other OEMs and race operations seeking a step change in thermal capacity and packaging without a complete cooling-system redesign.
