Sauber Engineering appoints 3D Systems to Power Constant Innovation

8 June 2021

Sauber Motorsports AG has built a highly productive in-house factory to support its high demand wind tunnel operations that was enabled by a 3D Systems solutions and long-term partnership. High throughput 3D Systems equipment and solution expertise coupled with best-in-class materials provides the high-quality parts needed for Sauber to test more aerodynamic model iterations.

Factory-Level Throughput Drives Constant Development

The pace of innovation at Sauber is relentless. In order to maximize its ability to drive rapid development on its car, Sauber Engineering has invested in an additive manufacturing machine park that is among the largest of its kind in Europe. Due to the proven throughput, quality, accuracy, and choice of best-in-class materials with 3D Systems 3D printers, this park includes fifteen 3D Systems machines across technologies.

According to Christoph Hansen, Director of Technology and Innovation at Sauber Engineering, additive manufacturing is an integral part of every Formula One team because it provides faster access to parts than conventional manufacturing methods. “Creating something in carbon fiber can take weeks before a single part is ready,” said Hansen. “Conventionally producing the quantity of parts we need for progress would be impossible in the time we have.”

Due to this need for speed, Hansen said lead time was the most important factor when selecting a 3D printing partner. However, it was not the only factor: “You have to produce more options to compete on the development side, but it’s not just banging out as many parts as possible. You also have to test and be sure it’s correct,” Hansen said.

Best-In-Class Materials Ensure High Quality Results

For the highest confidence in test results, best-in-class materials are necessary. At Sauber Group, part stiffness and surface finish are essential. Sauber Engineering produces an average of 100-150 3D printed part sets daily using 3D Systems machines. Of these, eighty- to ninety percent are SLA parts for wind tunnel testing that are printed using a selection of Accura® SLA materials, including:

Combined with Sauber Motorsport’s confidence in the quality of Accura materials, this high level of daily part production is critical to the team’s progress and ultimate success. “On each cycle we normally find an improvement,” said Reto Trachsel, Head of Aero Design at Sauber Motorsport, “and if you can now do 50 cycles it makes a big difference. The quicker we can produce the parts, the quicker our development cycles are, and the more progress we can make in our aerodynamics.”
