Just in time to ride the last of the pre-Super Bowl buzz, Carbon today announced that it’s teaming up with sports equipment giant Riddell to 3D print customized football helmet padding.

Referred to as “Diamond technology,” the collaboration creates lattice design pads of resin that are custom built to a player’s dimensions and position. Carbon says the pads were created by analyzing data from more than five million on-field collisions collected by Riddell smart helmets.
