Air box 3D printed in PA-CF for a rally engine

Welcome to hell: the engine bay of a rally car. 180 km/h, over 90 °C under the bonnet, constant vibration, dust and gravel: that is daily life for the air box we 3D printed. We printed this part in PA-CF, a carbon-fibre-reinforced polyamide that ticks every box. Heat resistance The part stays stable even right next to the engine block. Stiffness The carbon fibres limit deformation under mechanical load. Light weight A significant saving in mass compared with a machined or sheet-metal solution. Resistance to hydrocarbons An essential property in an engine environment. 3D printing now makes it possible to design bespoke technical parts, optimised and quick to produce: a real advantage in motorsport, where every gram counts.
