The University of Cincinnati Bearcats Motorsports team has achieved a significant breakthrough in the design and manufacturing of their Formula SAE race car’s front wing, leveraging cutting-edge additive manufacturing technologies and advanced materials. This innovative approach has not only drastically reduced weight and simplified construction but also demonstrated exceptional durability and performance under demanding racing conditions. The project, a collaboration with industry partners Vixiv, GZero Additive, and Lyten, represents a paradigm shift in how student engineering teams can access and implement state-of-the-art solutions, pushing the boundaries of what is achievable in competitive motorsport.
A Leap Forward in Design and Manufacturing Efficiency
The centerpiece of this advancement is the redesigned second element of the Bearcats’ front wing. The original component, a complex assembly of carbon fiber and aluminum, was a testament to traditional engineering but came with significant trade-offs in terms of production time and weight. The existing design and manufacturing process for this single component alone consumed approximately 65 hours of dedicated effort, encompassing design, machining, and assembly. The final product tipped the scales at a substantial 621 grams. This considerable time investment and weight were identified as key areas for improvement, especially in the highly competitive and performance-driven environment of Formula SAE.
The catalyst for this transformation was the integration of Vixiv’s sophisticated AI-driven design software. Vixiv, a specialist in design optimization, was tasked with reimagining the front wing element for additive manufacturing. The process began with Vixiv’s team uploading the existing 3D model of the component into their proprietary cloud-based platform. This platform is engineered to analyze design constraints and requirements, including load-bearing capacities and material thickness, and then intelligently generate optimized lattice structures. In a remarkable display of computational power and algorithmic efficiency, Vixiv’s AI engine processed the complex aerodynamic and structural requirements of the wing element and produced an optimized, 3D-printable design in an astonishing 34 seconds. This represents a monumental reduction in design time, moving from hours to mere seconds, and highlights the transformative potential of artificial intelligence in engineering workflows.
The Power of Additive Manufacturing and Advanced Materials
Following the rapid design optimization by Vixiv, the digital blueprint was handed over to GZero Additive, a prominent manufacturer specializing in large-format additive manufacturing (LFAM). GZero Additive’s expertise lies in producing large and complex parts using industrial-grade 3D printers. For this project, they utilized their advanced LFAM platform to fabricate the redesigned front wing element.
The material choice was equally critical to the success of this initiative. GZero Additive employed a cutting-edge filament developed by Lyten, a materials science company focused on advanced polymer composites. This filament was a graphene-reinforced nylon, a material engineered for superior strength, stiffness, and lightweight properties. The incorporation of graphene, a single layer of carbon atoms arranged in a hexagonal lattice, is known to significantly enhance the mechanical performance of polymers. This choice of material, combined with the optimized design, allowed for the creation of a 3D printed component that was not only structurally sound but also remarkably light.
The resulting 3D printed front wing second element weighed in at an impressive 395 grams. This represents a weight saving of over 226 grams compared to the original carbon fiber and aluminum part, a reduction of approximately 36%. Crucially, the additive manufacturing process also completely eliminated the need for assembly, further streamlining the production process and removing potential points of failure. The combined benefits of reduced design time, simplified manufacturing, and significant weight reduction positioned the Bearcats Motorsports team for a competitive edge.
Real-World Performance: Tested and Proven at FSAE Michigan
The true test of any engineering innovation lies in its performance under real-world conditions. The newly 3D printed front wing second element made its debut at the prestigious Formula SAE Michigan competition. This event is a renowned collegiate design competition that challenges engineering students to design, build, and race a formula-style open-wheel race car. It attracts teams from universities worldwide, fostering intense competition and a rigorous evaluation of engineering prowess.
During the dynamic events at FSAE Michigan, the 3D printed wing element performed exceptionally well. It successfully sustained structural loads ranging from 60 to 80 pounds-force (lbf) throughout the demanding competition. This demonstrates its ability to withstand the significant aerodynamic and mechanical forces encountered during high-speed racing.
Perhaps the most compelling testament to the component’s robustness came during an unforeseen incident. The team experienced an impact that resulted in the snapping of the endplates on the first element of the front wing. In many racing scenarios, such damage could lead to immediate disqualification or severe performance degradation. However, the resilient 3D printed second element of the wing played a critical role in mitigating the damage. It effectively held the broken assembly off the ground for the remainder of the event, preventing further damage and allowing the team to continue participating. This unexpected feat not only showcased the structural integrity of the Lyten material and GZero’s manufacturing capabilities but also highlighted the ingenuity of the Bearcats Motorsports team in designing a component that could perform beyond its primary aerodynamic function in a critical situation.
