In 3D printing has expanded in many uses. Recently I have studied that in the NFL are using 3D printing for better, protected helmets for each player. They customize a helmet for each player by scanning their head. On the website CNBC,it shows us how they scan their heads and how they can customise it for better protection. Some may ask is it worth the money it is because this product can change the way their head impacts on themselves when they they get hit. This image below shows how their scanning a players head for a better fit.
