The Contest of Formula Student is a prestige competition organized by the Institution of Mechanical Engineers and SAE Internartional.The task for the contestants is to design and build, and build car/bolide which will be racing in Formula 1 tracks.
Jelwek provided Prz Racing Team with 3D printing parts, like the gasket of rubber-like material NinjaFlex. It was nesseccary to restricted rules and finding the way to lose weight – which forced designers to use additive methods in parts making.
The NinjaFlex material has similar mechanical properties to rubber and it melts in 235 °C. That is why we decided to use in intake system of the internal combustion engine. The gaskets were designed in three sizes. The whole system is 100% hermetic, even when it works on 200 MPa pressure. The low part of the air intake was printed by the Jelwek company out of PLA material- with the require hardness for this of application.
