NASCAR Use Case for Aerodynamic Strake Prototyping

This document is a case study detailing the use of 3D printing technology by NASCAR for aerodynamic strake prototyping. The National Association for Stock Car Auto Racing, known for its innovation in performance engineering and vehicle design, faced challenges in optimizing aerodynamic performance for race cars. Traditionally, prototyping methods such as CNC machining and metal stamping were time-consuming and costly. To address these issues, NASCAR engineers utilized the Stratasys Neo®800 SLA 3D printer to create multiple strake designs using Somos® EvoLVe™ 128 material. This approach allowed for rapid design iteration and performance testing, significantly reducing costs by 50% and saving an average of one week in prototyping time. The 3D printing process enabled improved aerodynamic performance and facilitated low-clearance testing, which was not feasible with conventional materials. The case study highlights the advantages of 3D printing in the automotive racing industry, showcasing its impact on design efficiency and race performance.
