An iFixit report reveals that the USB - C port on Apple's iPhone Air makes use of 3D printing technology. Researchers, after closely examining its surface texture, dismissed the likelihood of binder jetting technology being employed. Instead, they proposed that Apple is utilizing pulsed laser ablation technology. Previously, Apple has highlighted the environmental advantages of 3D - printed titanium metal. This year, by substituting stamping processes with 3D printing, the company has managed to conserve over 400 metric tons of primary titanium metal. Moreover, the cases of this year's Apple Watch Ultra 3 and the titanium variant of the Apple Watch Series 11 also incorporate 3D printing technology, which has led to a 50% reduction in the amount of raw materials utilized. Apple has set a goal to achieve carbon neutrality for its corporate carbon footprint by 2030. At present, the electricity used in the production of the Apple Watch is sourced entirely from renewable energy.
