The Cadillac Formula 1 Team has integrated 3D Systems’ stereolithography (SLA) technology to meet the rigorous development timelines required for its entry into the FIA FORMULA ONE WORLD CHAMPIONSHIP. By deploying seven large-format systems, the team established a tool-free manufacturing workflow that eliminates traditional lead times associated with component fabrication. This approach is critical for the rapid iteration of aerodynamic profiles within the automotive data ecosystem, specifically for wind tunnel testing prior to the 2026 season opener in Australia.
Technical specifications of production-grade SLA systems
The deployed technical solution integrates 3D Systems software with high-performance materials, including Accura Xtreme White 200, Accura Xtreme Black, and Accura HPC. These materials are engineered to deliver production-grade quality characterized by:
- Feature Precision: High-resolution capabilities for sharp part corners and small extruded or embossed details.
- Surface Integrity: Superior side wall detail and smooth layer lines on angled faces, which are essential for minimizing turbulence during high-velocity wind tunnel simulations.
- Structural Durability: Materials designed to withstand the mechanical stresses encountered during testing and final component use.
Engineering collaboration and industry standards
To navigate the stringent technical requirements of Formula 1, described as one of the most significant challenges for mechanical component manufacturers, Cadillac worked with the 3D Systems Application Innovation Group (AIG). This collaboration focused on co-developing solutions that ensure high-precision, repeatable production at scale. The use of additive manufacturing in this context supports a digital supply chain by allowing design modifications to be transitioned directly from simulation to physical testing without the need for specialized tooling.
Operational impact on race deadlines
The ability to produce parts rapidly was a decisive factor in the team's qualification for the 2026 season. By significantly reducing the weeks of lead time typically required for mechanical components, the team could maintain its development trajectory despite rapidly diminishing race deadlines. This implementation demonstrates how additive manufacturing provides the necessary flexibility to respond to evolving technical regulations and performance data in real-time.
Additional Context
This section details technical specifications and competitive benchmarking not included in the original product announcement.
The use of SLA technology in Formula 1 benchmarks favorably against traditional CNC machining for complex aerodynamic surfaces, often reducing the cost per part for prototypes by over 50%. While Selective Laser Sintering (SLS) is also common in motorsport for functional housing, SLA remains the industry standard for wind tunnel models due to its superior surface finish (Ra values typically below 0.2 µm after minimal processing), which is vital for accurate boundary layer simulation. Compared to competitors like Stratasys or Carbon, 3D Systems’ Accura HPC (High Performance Composite) specifically offers a high tensile modulus (up to 5,500 MPa), providing the stiffness required to prevent part deformation under high-pressure wind tunnel loads.
