A high-performance 3D-printed windshield air intake and under-windshield NACA duct will be featured on each car.
The National Association for Stock Car Auto Racing, LLC (NASCAR) plans to produce the first-ever 3D-printed production parts that will be incorporated into all of its NASCAR Next Gen cars.
One of the key components that will be printed is a windscreen and cockpit ventilation unit. To do this, the American motor racing operating and sanctioning company works with Stratasys Direct Manufacturing for production, a Stratasys company that manufactures parts on demand.
This is not the first collaboration of the two companies who have worked together on multiple projects for nearly 20 years. Together they have created highly competitive race cars, using 3D printing to support tooling, drill guides and now production parts.
In this specific case, the production team at the Texas-based Stratasys site used the 3D printer Stratasys H350™ powered by SAF™ and one material PA11 high yield derived from sustainable castor oil. Parts were cleaned, finished, tinted and shot blasted using DyeMansion post-processing equipment.
The new 3D printed parts provide NASCAR with increased performance, greater flexibility, cost savings and better aerodynamics, and are used by all teams competing in the NASCAR Cup Series. These parts are the culmination of nearly three years of planning, design and development, with the Next Gen car having undergone more than 37,000 miles of testing before its introduction at the Busch Light Clash in February, a press release says.
» The Next Gen car could not have been completed without the collaboration with NASCAR’s competition partners like Stratasys and Stratasys Direct Manufacturing « , said John Probst, senior vice president, racing innovation, NASCAR. » During testing, we realized that we needed an additive manufacturing solution that could withstand high temperatures and that parts needed to be delivered quickly. We contacted Stratasys Direct, and they responded not only as a supplier but also as a consultant on this project. They provided us with strategic direction on design, materials and the right additive manufacturing technologies to use to create the best performing parts for Next Gen cars.. »
