Apple Uses AI and 3D Printing to Build iPhone Duo Hinge

September 10, 2026
Apple uses AI algorithms and 3D printing in the manufacturing process for the hinge in its first foldable iPhone.

Apple Inc. unveiled the iPhone Duo in a press release, its first foldable iPhone. Its manufacturing process uses AI algorithms to match each hinge with the housing that provides the best fit.

A confocal laser scans the surface of every unit. Apple then uses 3D printing to apply up to 25 microscopic layers of a custom photopolymer, which removes remaining surface irregularities and improves alignment.

The iPhone Duo has a 7.6 inch inner display, a 5.4 inch outer display, a titanium body and an IP68 rating. It starts at $1,999, with preorders opening October 16 and availability beginning October 23.
