The hinge for Apple’s new foldable phone was built with AI

Apple’s new Duo foldable phone uses an AI-driven process to match each hinge to its housing, with a confocal laser scanning the part’s topology and 3D-printing up to 25 micro-layers of custom photopolymer to remove waviness. The device also features a nano-texture finish that cuts glare and a multilayer lamination scheme intended to boost overall durability.
