Sports brand Nike has unveiled the first boots for American football players with 3D-printed studs. Nike's Vapor Laser Talon boots are fitted with a footplate made by selective laser sintering, a process that uses lasers to fuse small particles of material together. With laser sintering, Nike's designers were able to prototype the boots much faster than usual and make updates as they went along. In future, boots could be individually shaped for each player. The 3D-printed footplate also makes the boot extremely light, weighing in at 158 grams, and improves traction on the turf to help players run faster. According to the sportswear company, the boots can markedly improve a player's "40-yard dash" time – the standard measure used by scouts to assess speed and ability.
