Apple's 3D Printing Revolution: How Your Next Apple Watch Will Be Made from Powder

Apple continues its confident drift towards maximum production optimization, and this time traditional milling is under the knife (or rather, under the laser). According to well-known Bloomberg insider Mark Gurman, the company plans to transition most aluminum cases for the Apple Watch to 3D printing technology. In the long term, this fate also awaits iPhones, which effectively means a small industrial revolution within Cupertino's walls.

From titanium to mass aluminum

This decision did not come out of nowhere. Apple has already tested the method of additive manufacturing on more complex and expensive materials. In particular, some titanium parts for the Apple Watch Ultra 3 and the compact USB-C port in the new iPhone Air are already made this way. Now that the technology has proven its viability in small batches, the company is ready to scale it to the most common metal in its arsenal — aluminum.

Currently, the industrial design team, along with the operations department, is actively "refining" the technological processes. The main challenge is to maintain the usual surface quality and strength that users are accustomed to, while radically changing the way the device's "box" is created. Gurman, who has already established himself with accurate predictions regarding the price of the iPhone 17e, claims that the transition is just a matter of time.

Economics must be economical

The main driver of these changes is Apple's simple desire to spend less and get more. The traditional method of casing manufacturing involves forging and subsequent milling on CNC machines. It looks impressive in commercials, but from an ecological and financial standpoint, it's horrible. A massive amount of metal simply turns into shavings that then need to be recycled. 3D printing allows material to be used almost loss-free: the powder sinters exactly where needed according to the blueprint.

In addition to saving metal, Apple gains the following advantages:

• Reduction in production cycle time for one case.
• Reduction in logistical costs for waste disposal.
• The ability to make design changes faster without retooling entire production lines.

Technological tricks inside the case

But not just money. 3D printing opens doors for engineers that were previously locked. For example, the printer can create complex rough textures on the internal walls of the case. A standard milling tool simply cannot reach such places at the right angle.

Why is this needed? Apple uses these microtextures to improve the adhesion of metal to plastic inserts in antenna zones. This not only makes the structure stronger but also enhances water resistance. Thus, the transition to printing is not an attempt to cut costs at the expense of quality, but a way to achieve what was previously technically impossible. Even if the user never sees these "internal labyrinths," the device will only become more reliable. The official Apple is still silent, but the logic of its product development fits perfectly into this scenario.

While Apple masters case printing, scientists are going even further: for example, MIT recently taught a 3D printer to print electric motors for the price of coffee, which may completely change the approach to creating consumer electronics in the future.
