10. Performance
English Racing turned to 3D printing this year after destroying several engines of their high-performance sports cars. The team’s engineers envisioned and 3D printed a stainless steel pulley that could tolerate the demands of the racetrack. Although English Racing reached 184.9 miles per hour and won their class competition, the speediest thing about their process was the fact that creating this integral end-use part took only 5 hours.
