CASE STUDY: AUTOMOTIVE

F1 team saves weight by printing 143 metal parts on MetalFAB1

Sauber Motorsport AG, which manages and operates the Alfa Romeo Racing ORLEN team in the Formula One world championship, has unveiled its 2020 contender, the C39, before the start of winter testing in Barcelona.

Race drivers Kimi Räikkönen and Antonio Giovinazzi, alongside reserve driver Robert Kubica and development driver Tatiana Calderon, pulled the covers off the C39 during a roll-out presentation in the pitlane at the Circuit de Barcelona-Catalunya.

The 143 metal 3D printed parts (58 Ti, 19 high performance aluminium alloy and 66 AlSi10Mg parts) printed on Sauber Engineering’s four MetalFAB1 systems saved at least 2% of the car’s weight, which will be very beneficial for the car’s performance.

The part type ranges from chassis inserts to cooling circuit piping, from safety structures to light weight fairings and from electronic component installation to bodywork components.

Jan Monchaux, Technical Director, Alfa Romeo Racing ORLEN said: “The C39 is a natural evolution of last year’s car, even though it doesn’t share a lot with its predecessor. We have been further improving our car but, apart maybe rims and tyres and some internal components, there is barely a single visible part that is the same.

“It’s the usual process of constant improvement, but it’s a brand new beast. We expect to improve on what we achieved last season, to make a step forward and hopefully be able to fight for the position at the top of the midfield.”
