Overview
- All Apple Watch Ultra 3 and titanium Apple Watch Series 11 cases are manufactured with 100% recycled aerospace‑grade titanium powder.
- Apple estimates the change will save more than 400 metric tons of raw titanium in 2025.
- Cases are built from atomized powder using six synchronized lasers at 60‑micron layers—about 900 layers per case—followed by depowdering and automated optical inspection.
- Additive manufacturing enables improved waterproofing in cellular models by creating a stronger bond between the metal case and the antenna housing.
- The same 3D‑printed recycled titanium method forms the iPhone Air’s USB‑C port enclosure, which is thinner, stronger, and uses about 33% less material.
