A recent report from China indicates that Apple's upcoming iPhone Fold will feature a 3D printed hinge, which aims to significantly reduce the crease on its folding display. This detail marks the first time specific information about the hinge's manufacturing process has emerged. The technology is not entirely new, as it has already been successfully implemented in Oppo's Find N6 model, which features a Titanium Flexion hinge created through 3D Liquid Printing technology. Oppo's approach achieved a 'zero-feel crease' by meticulously measuring hinge depth and applying a 3D liquid polymer to create a slimmer design. Apple has a history of utilizing 3D printed components, including in the casings for its Apple Watch series and the USB-C port of the iPhone Air. This manufacturing process is not only innovative but also more efficient, using less material compared to traditional forging methods. Reducing the crease in the folding display is reportedly a major design goal for Apple as it prepares to launch the iPhone Fold.
