Larsen Motorsports: a steering wheel fitted to one driver, in 2 days instead of 8
A jet dragster runs at 280 mph, and its off-the-shelf butterfly steering wheel is built to standard hand dimensions, so driver Josette Roach could not reliably reach critical controls. The team printed a fitted wheel on an X7, with Onyx as the base and continuous carbon fiber laid along the load paths, cutting part lead time from 8 days to 2. In real-world testing it was stiffer than the aluminum original, which flexed under load. Simulation software predicted the loads up front, so the team did not need to print ten intermediate versions to find the failure point.
