A Formula-1 pit stop should take no longer than 12 seconds, anything beyond that time frame will result in distance lost to eager competitors. This extreme time constraint and pressure is not only experienced by the pit stop crew but by product development teams in the racing industry (although they get more than 12 seconds to produce a functioning product). Auto race teams face the tightest product development schedules of any business. During race season, teams often have just a few days to fix a problem identified in the previous race. They need to create a new design, 3D print a prototype, validate its performance, fabricate a part, and install in on the car in time to be shipped to the next weekend’s race. It is no surprise that race teams are leading the way in the use of direct digital manufacturing (DDM) to produce parts for racing vehicles.
