Apple’s manufacturing teams are testing a new method to produce aluminum device shells using 3D‑printed aluminum. The approach, outlined by Bloomberg reporter Mark Gurman, would let the company shape enclosures layer by layer, trimming waste and cutting cycle time. Early prototypes target the Apple Watch, with the technique expected to roll out to other products later in the near term for Apple.

The MacBook Neo, unveiled at $599, already employs a streamlined aluminum‑forming process that conserves material compared with traditional stamping. Gurman notes that extending a similar 3D‑printing workflow could further reduce raw‑metal usage across Apple’s lineup. The move follows the company’s recent rollout of 3D‑printed titanium cases for the Apple Watch Ultra 3, signaling a broader shift toward additive production.

Industry analysts see the strategy as a way for Apple to tighten supply‑chain control while meeting sustainability goals. By printing enclosures on demand, the firm could shorten inventory cycles and respond faster to design tweaks. If the technique proves reliable, future iPhone generations may adopt the same process, giving Apple a manufacturing edge that could translate into lower retail prices.
