The 1,000+ parts involved in such vehicles are typically produced using injection molding at a cost of USD$20-40K, with a month of turnaround time. However, MCD invested in a Dimension 3D printer and has used it to develop over 200 prototypes at far lower cost and much faster turnaround time (days).
But note – the parts produced on the 3D printer are not actually used in the final vehicles. While parts are pretty strong, they simply won’t withstand the extreme environment at ultra-high speeds. Instead, the 3D printed parts are used in lower-speed testing to validate their function before full-on aluminum injection molding is attempted.
