A team of innovative engineers is transforming the way vehicles are developed by PRINTING car parts.

CUPRA, which is the performance arm of SEAT, is using state-of-the-art, multi-jet fusion technology to fashion parts in a fast and efficient way.

They 3D printed the door mirror, air intakes and cooling intakes for the new race spec Leon Competici n model.

The process of printing a mirror can take around 20 hours, but as they can print six at a time it gives the team the ability to create different designs simultaneously.

This way they can quickly test the varying prototypes in a wind tunnel to find out which is best for aerodynamics.

When taken to this controlled environment, the printed parts are fitted to the car and face winds of more than 180mph while sensors study the impact on individual surfaces.

The car's resistance data is displayed on screen and the engineers and designers compare the results for the different printed wing mirrors and grilles.

As the smallest margins can make the difference in motorsport, it is crucial the 3D printed parts play their part in reducing fuel consumption while also increasing stability, speed and safety.

Xavi Serra, head of technical development at CUPRA Racing, said: "For the new CUPRA Leon Competici n we modelled the steering wheel's centre control module, the bonnet air vents, door mirrors and the brake and water cooling inlets.

"The main goal is to have a lot of parts in a short time. We can quickly test a wide variety of designs and furthermore, since vehicle development is now done in parallel, this technology enables us to react swiftly to any changes in the design process.

"The bigger the variety of parts we can test in this facility, the better. It enables us to make much faster progress.

"The results were excellent, and some were even surprising, because we were looking to push the material to its limits.

"This technology is and will continue to be key in countless fields to make the most complex ideas a reality."

The final development of the 3D printed parts was on a racing circuit, with CUPRA testing the Leon Competici n on the Portimao track in Portugal.

So far, CUPRA has been printing parts for its Leon Competici n, its 180mph touring car inspired by the new Seat Leon family hatchback, and the e-Racer, an electric touring car which does 0-60mph in 3.2 seconds.

CUPRA has released footage of the printing and test processes of the project, which is in partnership with HP.

Virginia Palacios, head of systems product management, 3D Printing & Digital Manufacturing, HP Inc, said: "The work with CUPRA demonstrates the power of 3D printing and digital manufacturing – changing the way the world designs and manufactures.

"3D printing is going to signal a turning point in the automotive industry by accelerating lead times and HP 3D technology is helping designers create parts that could not be produced with other technologies."
