The Need for Speed and Precision
In the world of motorsports, where every millisecond counts, teams are constantly seeking a competitive edge. This pursuit has led to an exciting development – the integration of 3D printing technology into racing, including cars and bikes used in events such as Formula 1, Indy 500, and NASCAR. The high-performance demands of motorsports, including mechanical stresses, extreme temperatures, and high g-forces, have made it a perfect proving ground for cutting-edge technologies.
Chevrolet’s 3D Printing Triumph
One standout example comes from General Motors (GM). In 2020, Chevrolet race cars completed an astonishing 80,000 miles with the assistance of hundreds of 3D printed parts. These parts played a crucial role in events like the Indy 500 and the 24 Hours of Daytona. In the highly competitive world of motorsports, where every advantage matters, these 3D printed components made a significant difference.
For instance, the Chevrolet Corvette C8R, a race car with an impressive track record, featured over 75 3D printed parts, including the oil tank, air conditioning components, and even the integrated hydration system. Approximately half of these parts were created in-house by General Motors. These components have endured close to 8,000 miles of racing across ten races.
IndyCar, a pinnacle of American open-wheel racing, witnessed Chevrolet’s innovative use of additive manufacturing. They harnessed 3D printing for components in their Indy V6 engine, particularly in the exhaust system. Not only did this enhance reliability, but it also offered more design flexibility and reduced production costs. Chevrolet’s Indy cars impressively covered more than 60,000 miles in the 2020 season, showcasing the durability of 3D printed parts.
3D Printing All Around: NASCAR and Beyond
The influence of 3D printing isn’t limited to one racing series. In the 2020 NASCAR Cup Series, Chevrolet unveiled the Camaro ZL1 1LE. To design this new race car, more than 500 3D printed prototype parts were employed in the wind tunnel. Additionally, a 3D printed gear cooling duct contributed to over 18,500 miles of racing in 27 competitions.
BMW’s Motorrad Motorsport division, which competes in the FIM Superbike World Championship with the BMW S1000RR, uses portable 3D printers stationed in their pit area. This allows them to produce on-the-fly improvements to their motorcycles. The team prints parts that range from brake ventilation systems to sensor holders, optimizing the bike’s performance. In the world of motorsport, these rapid manufacturing capabilities can make a huge difference.
The Power of Partnerships
Toyota joined forces with 3D Systems in a partnership that began in August the previous year. Their collaboration aims to pioneer a manufacturing solution that includes 3D printers, materials, and software. They envision a future where additive manufacturing revolutionizes automotive design and production. Their achievements in motorsports demonstrate how innovative technologies can provide a competitive edge.
McLaren Racing, one of the giants of motorsport with a rich history, also embarked on a four-year partnership with Stratasys. Stratasys serves as the official supplier of 3D printing solutions to McLaren Racing’s Formula One team, helping them speed up car development. From tools to car parts, McLaren Racing utilizes additive manufacturing to ensure their Formula One cars are at the forefront of technology.
Conclusion
3D printing has taken motorsports to new heights. From Chevrolet’s exceptional performance to BMW’s innovative on-site production, and the partnerships between Toyota and 3D Systems and McLaren Racing and Stratasys, additive manufacturing is reshaping the industry. As the demand for speed and precision in motorsports continues to rise, 3D printing will play an increasingly vital role in giving racing teams that extra edge over the competition.
