In 2021, NASCAR introduced its Next Gen platform, which brought several rule changes compared to the previous version. The latest NASCAR vehicles are now fully symmetrical and use composite body panels instead of metal, resembling the street versions of the Chevrolet Camaro, the Ford Mustang, and the Toyota TRD Camry. Race car driving can be an expensive sport, and one of the objectives of the Next Gen platform was to reduce operating costs and ensure parity across the board. Technique Chassis, the exclusive chassis manufacturer for the NASCAR Cup Series, builds a modular offering in three parts. This approach ensures that everyone starts with the same platform, with the opportunity to find a competitive edge in the smallest details. A smart way to stand out from the competition is through the use of 3D-printed parts. However, this is not your typical hobbyist-level 3D printing. Additive manufacturing, also known as 3D printing Minnesota-based Stratasys specializes in additive manufacturing, which involves building an object layer by layer. Stratasys' Senior Global Director of Automotive & Mobility, Fadi Abro, explains that while this process is often referred to as 3D printing, additive manufacturing is typically associated with industrial solutions rather than hobby-level projects. Additive manufacturing differs from subtractive manufacturing, where material is cut away from a solid piece to create the final product. In the context of NASCAR, Stratasys provides parts like ducts, covers, brackets, and tubing, collaborating with the racing organization to meet current driver needs and suggest additional parts and modifications.

CNC is a subtractive process, as explained by Abro, and is more restrictive compared to additive manufacturing. According to Abro, additive manufacturing offers more design freedom. With CNC machining, limitations arise when trying to make sharp turns or complex shapes, whereas additive manufacturing allows for greater design complexity without significantly increasing costs or lead times.
