Apple’s long-awaited foldable phone, the Duo, features a critical hinge designed and built with the help of artificial intelligence and 3D printing, according to company disclosures. The device marks Apple’s first entry into the foldable phone market, a hardware category known for strong consumer interest alongside persistent durability challenges.
Overcoming Foldable Phone Durability Hurdles
Foldable devices undergo twice as much mechanical wear as traditional smartphones by design. Because of this repeated stress, most existing foldables suffer significant physical degradation over time, failing to match the longevity of standard slab-style handsets.
To combat this, Apple claims it integrated innovative protections into the Duo to prevent typical wear and tear. According to Johny Srouji, Apple’s chief hardware officer, the phone’s hinge mechanism relies on advanced manufacturing techniques to ensure structural integrity.

AI-Driven Manufacturing and 3D-Printed Micro Layers
The engineering behind the Duo’s hinge involves a multi-step digital and physical assembly process. Apple utilizes computational tools to pair individual components for optimal fit.
“During manufacturing, we use AI algorithms to precisely match each individual hinge with its best-fit housing to ensure perfect alignment, and a confocal laser progressively scans the topology of every single unit, and 3D prints up to 25 micro layers of a custom photopolymer to eliminate residual waviness,” Srouji said during Apple’s Surprise and Shine event.
By applying up to 25 micro layers of custom photopolymer, the manufacturing process addresses microscopic surface imperfections that could otherwise weaken the moving parts over thousands of open-and-close cycles.
Display Enhancements and Anti-Glare Technology
Beyond the mechanical hinge, Apple equipped the Duo with a custom nano-texture finish aimed at minimizing environmental reflections. Srouji noted that this finish significantly reduces glare.
The device also features a multi-layer lamination strategy. This approach is intended to reinforce the flexible display panel against repeated folding stress, though long-term consumer testing will ultimately determine how well these protections hold up under daily use.
