3d printing in Formula 1

Once upon a time an F1 car was made using hand crafted tools shaping metals and cutting and tapping and boring. You needed a lot of patience to work this way where parts came out precise and accurate. Perfected. 

These days Formula 1 cars rely heavily on cad cam and rapid prototyping otherwise known as 3d printing. Car designers have these fantastic machines at there disposal and still they cant seem to make the parts fast enough for the hundreds of iterations of a design for a single part.

There is definately a limit to layer object manufacturing and it looks like that may be reached sooner than expected.
