A fresh report from Apple supply chain sources in China points to a key design shift for the upcoming iPhone Fold. The device is now expected to use a 3D-printed hinge to reduce the visible crease on its folding display. This is the first time detailed information has surfaced about 3D printing being used in the hinge. Earlier rumors had already suggested the use of liquid metal and dual-layer glass in the same component.
This approach is not entirely new in the foldable market. Oppo introduced a similar idea with its Oppo Find N6. The company used a second-generation Titanium Flexion hinge to improve durability and reduce the crease. It relied on laser measurements at a microscopic level to detect variations in hinge depth. Then, it applied 3D liquid polymer to smooth out the structure and make it thinner than earlier foldable hinges.
Previous reports also suggest that the iPhone Fold aims to match the crease control seen in the Oppo Find N6. This area remains a major priority for Apple. The company already has experience with 3D-printed parts. It uses 3D-printed titanium casings in its Apple Watch lineup and for the USB-C port in the iPhone Air. Moreover, 3D printing improves efficiency and reduces material waste compared to traditional forging methods.
