Apple Explores 3D‑Printed Aluminum for Watch Casings, With iPhone Enclosures a Longer‑Term Target

The effort targets lower waste with potential cost savings.

Overview

  • Apple’s manufacturing and operations teams are developing ways to 3D‑print aluminum, initially for Apple Watch casings and potentially for iPhone bodies later, according to Bloomberg’s Power On.
  • Apple has not announced a timeline or confirmed mass‑production plans for aluminum 3D printing.
  • The company already uses 3D‑printed titanium in Apple Watch Ultra 3 and Series 11 and employed the process for the titanium USB‑C port in iPhone Air.
  • Apple’s recently launched MacBook Neo uses a new forming approach that cuts aluminum consumption by about 50% versus traditional machining, demonstrating material‑efficiency gains.
  • Reports note significant hurdles for aluminum printing, including high thermal conductivity and reflectivity, risks of warping or internal voids, and likely shifts away from Apple’s usual 6000‑series alloys.
