RP2 is a sponsor of the Delft University racing team. Special cooling hoods have been designed for the electric motors of the DUT18 racing car of the Formula Student Racing team Delft. Diabatix calculated with a flow optimization the geometry for the interior of the cooling hoods. The four hoods were printed in PA12 on our HP MultiJet Fusion machine. That they have functioned well is proven by the team. They won the competition of 2018.
