Just a fraction of a second can make the difference in Formula One. Over the course of a season, these smallest of margins can separate the winner of the motorsport championship from the also-rans.
One of the ways UK-based McLaren-Honda is looking to capture those marginal gains is with the use of a portable 3D printer, which it took to a Grand Prix event for the first time this month in Bahrain.
It is evidence that 3D printing is finding more real-world applications after years of buzz around a technology that it is hoped will have a transformational effect on wide areas of manufacturing.
Although there are barriers to its widespread use, F1 shows how it is slowly gaining a position in tool kits for industrial production.
