Claims of a 3D-printed hinge for the iPhone Fold are on the agenda. This technology, aiming to reduce the crease, points to significant changes in Apple's manufacturing approach. Here are the details:
A new claim regarding the iPhone Fold, expected to enter the foldable phone market, focuses on one of the device's most critical components: the hinge system. According to reports from Chinese sources, Apple plans to use a hinge produced with 3D printing technology to reduce the crease problem, one of the biggest issues with foldable screens. The same report suggests that Apple might also consider materials like liquid metal and dual-layer glass, which were previously rumored, for this structure.
iPhone Fold Could Reduce Crease with 3D Printed Hinge
In foldable phones, the hinge mechanism stands out as a crucial component that plays a decisive role in the device's long-term usability. Hinges developed with traditional manufacturing methods can, over time, create a noticeable crease on the screen. This is considered one of the most significant factors negatively affecting user experience. 3D printing technology, at this point, offers more precise manufacturing tolerances, allowing the hinge to be optimized at a microscopic level.
A similar approach was previously developed by Oppo and used in the Oppo Find N6 model. The second-generation titanium flexible hinge used in this device was produced with 3D liquid printing technology. Oppo's method involved analyzing the hinge depth with laser measurements and then flattening the surface with a 3D liquid polymer. This allowed the company to achieve what it described as a near-zero crease. Apple's adoption of a similar engineering approach indicates that the iPhone Fold is directly preparing for competition in this segment.
For Apple, 3D printing technology is not an entirely new field. The company already uses titanium-based 3D printing production techniques, especially in Apple Watch models and some iPhone components. This manufacturing method generates less material waste compared to classic forging and cutting processes, while also enabling the production of more complex geometries. When it comes to a foldable device, this flexibility provides a critical advantage in optimizing moving parts like the hinge.
Reducing the crease problem is not only seen as an aesthetic improvement. It also directly impacts the long-term durability of the screen. Foldable OLED panels can deform over time due to continuous bending. At this point, the support provided by the hinge system can reduce the mechanical stress on the screen, extending the panel's lifespan. Apple is thought to be aiming to distribute this stress more evenly with 3D printing.
