Chevrolet race cars with 3D printed parts cover 80,000 miles

The automaker Chevrolet, a division of General Motors since 1918, announced that its race cars have covered 80,000 miles, or approximately 130,000 km, with 3D printed parts this season. Led by the parent company, the automaker is placing additive manufacturing at the heart of its developments, whether in the prototyping or end production phases. For instance, in January 2020, two new Corvettes entered the racetrack, each with 75 3D printed parts, including the oil tank, the fuel tank inlet and cap, the driver’s cooling box and the integrated hydration system, etc.

The applications of 3D printing in the automotive industry are increasingly numerous, demonstrating the potential of the technology: manufacturers are designing pistons, brake pedals, and many other components to customize the interior of a vehicle. Nowadays, it is almost rare to see a big name among car manufacturers not interested in 3D printing. General Motors is no exception. It has been investing in additive manufacturing for a few years now – in 2018, the company revealed that it had saved more than $300,000 in two years with 3D printing and wanted to standardize this manufacturing process to design thousands of finished parts. So it’s no surprise that GM’s Chevrolet subsidiary is actively integrating additive manufacturing in its production activities.

Jim Campbell, US Vice President of Performance and Motorsports at General Motors, the parent company of Chevrolet, says, “Chevrolet has a long history of technology transfer between our motorsports and production teams, and this is a perfect example of our approach. GM’s 3D printing capability speeds up our learning cycles and, in turn, these racetrack experiences help our additive manufacturing team move one step closer the using 3D printed parts in production vehicles.”
