We chose printed components because of the possibilities offered by 3D printing technology.
We reduced the weight and increased the performance of our vehicle. All this, combined with the fast turnaround time, allowed us to start the engine calibration process on the dynamometer sooner.
We chose MJF technology over FDM because of the tightness of the components – the intake system cannot afford leaks. The PA12 material is also resistant to high temperatures.
The venturi in the intake system must be able to withstand the vacuum without deforming. This is the case when the throttle is closed and the engine acts as a vacuum pump and the intake system components deform inwards.
