Although the 3D printed serpentine belt does not work well, or at least long, the world of 3D printing is still fascinating.
It would be interesting to see what it means for cars in the future. There are companies out there offering cars that can be printed in 3D and put together by the end user, but what if you decided to start printing your own car parts? For instance, a serpentine belt?
You definitely would not try the same for a timing belt, but regardless, it is still a cool experiment.
