China3D printingNet February 21st, with its unique ability to quickly and cost-effectively produce a small number of special parts, it will3D printingIt is not surprising that it is increasingly used in the field of racing. The newest user is CUPRA Racing, the racing division of SEAT, the Spanish subsidiary of Volkswagen Group. To design, test and produce parts for its new Leon Competición, CUPRA relies on HP’s Jet Fusion 5200.

In order to accelerate the development of the new 2020 SEAT Leon racing version CUPRA Leon Competición, the design team turned to3D printing. This makes it possible to quickly iterate and test new features, which is very important because the development of the car and its equivalent products appear at the same time. Therefore, any changes made during the design of the production Leon can be implemented in the Competición version. The parts printed by the team include the steering wheel’s central control module, hood ventilation holes, rearview mirrors, and brakes and water-cooled air intakes.

Racers have various specifications that are different from traditional street cars. However, in the TCR International Series, the rearview mirror must actually have the same shape as the car production version. The CUPRA team maintained the shape of the structure, but added powerful functions by merging air intakes.

In the wind tunnel, yes3D printingThe parts are verified to ensure that their performance is the same as traditionally manufactured parts. Subsequently, the car was tested before the official release of the car on February 20, 2020, which coincided with the inauguration ceremony of the new headquarters of the racing brand CUPRA Garage.
Leon Competición will be racing on the Portimao circuit in Portugal, which will3D printingThe real quality of the parts is tested. At the same time, customers who are interested in buying a racing car can book in advance, this is the first touring racing car (modified road car). 10 batches of products are now available for pre-order and will be delivered at the CUPRA garage in Barcelona, Spain in April 2020.
Although3D printingIt may be new to CUPRA, but AM has been a standard feature of motorsports for some time.Other examples include McLaren’s use of Stratasys technology for track side printing, and Nissan’s implementation of prototypes and end parts3D printing, And Penske (Team Penske) uses Stratasys’ new carbon fiber filament3D printingMachine to manufacture fixtures, fixtures and prototypes. Many Formula One teams rely on AM, such as Ferrari, Alfa Romeo and Sauber.Many student teams also rely on3D printingCarry out your own racing project.
Perhaps one of the more interesting examples is BMW’s3D printingThe technology is used in the water pump wheels of its German Touring Car Master (DTM) vehicles.As early as 2010, BMW began to use laser powder bed fusion technology for this part3D printing, Replacing multi-piece plastic parts with a single metal part.As of 2015, BMW has equipped its DTM racing and Z4 GT3 customer cars with3D printingOf 500 water pump wheels.
In view of the high costs incurred when manufacturing these high-performance parts using conventional manufacturing methods, the application of AM in racing cars is very natural. And, as the CUPRA team has learned,3D printingAble to carry out the rapid iterations required by the design, and each small improvement can reduce the time to finish the track by a few milliseconds.So in motorsports, the question is not who is using3D printing.But how to use3D printingTechnology improves efficiency.
