For the very first time, the enclosures of both the Apple Watch Ultra 3 and the titanium Apple Watch Series 11 are being produced entirely through additive manufacturing using 100% recycled aerospace-grade titanium powder.

This is not a small experiment or a limited run. Apple’s design and engineering teams committed to scaling this process to mass production. To begin, they had to demonstrate through repeated prototyping and rigorous data collection that 3D printing could meet Apple’s exacting quality standards.

Sustainability was at the heart of the project. By shifting from traditional subtractive manufacturing, which discards large amounts of raw material, to an additive approach, Apple managed to cut the raw titanium used in each case by half when compared to prior generations. This
