Nike is showing off a new cleat designed to help American football players excel in the all-important 40-yard dash. NFL scouts regard the dash as incredibly important, and Nike’s new shoe is designed to help athletes decrease their times. What makes the Nike Vapor Laser Talon interesting is its 3D-printed cleat plate, which is a first for athletic cleats.
The 3D-printed portion of the cleat is made using Selective Laser Sintering (SLS) technology, in which a high-powered laser is used to selectively fuse thermoplastic particles into the desired solid shape; in this case, the cleat plate.
