The team also uses PEI a lot inside their high-voltage accumulator. With its fire resistance and high strength abilities, PEI is again the perfect choice for many parts inside the accumulator. One of these parts is Air Geo, which is located inside the accumulator at the back of the car. This component serves as a housing for cables, relays, fuses, and numerous PCBs, ranging from light indicators for the accumulator to the accumulator management system.
The tank holder is a new part in this year´s racing car. The part is printed on the FUNMAT PRO 610HT with the material choice of ABS. For the driverless disciplines, the team uses pressurized air to activate the brakes in an emergency. This year, they changed the concept of how pressurized air is stored, which required a new mounting solution. The tank holder is designed to solve this challenge.

Other 3D printed parts, using the FUNMAT PRO 610HT and PC material, are the flap ribs that play a crucial role in the construction of the car’s side wing. These ribs are glued into the carbon-fiber shells and incorporate threaded inserts for attaching the wing to the chassis.
While the team has used these ribs for years, they have redesigned for this season to accommodate changes in the aerodynamic shape of the wings. Using INTAMSUITE™ NEO and the 3D printing technology, they conducted topology optimization to achieve the lightest possible geometry, resulting in an organic shape that would not be possible to manufacture by milling.
