Apple continues to expand its use of 3D printing as it looks for new ways to build device enclosures while reducing manufacturing waste and improving efficiency. The company already uses the technology in several recent products, and its engineering teams now want to apply the same process to more materials and more devices across the lineup. If that effort succeeds, future Apple Watch and iPhone models will rely more heavily on parts produced through 3D printing.
The shift started with titanium components. Apple introduced a 3D-printed titanium shell with the Apple Watch Ultra 3, and the company also uses the process for the titanium version of the Apple Watch Series 11. Apple also applied 3D printing to the USB-C port design on the iPhone Air, which helped engineers create a thinner port while keeping the device slim and durable.
According to Bloomberg’s Mark Gurman in the Power On newsletter, Apple now plans to take the next step by experimenting with 3D-printed aluminum enclosures for future products.
“The company’s manufacturing design team along with its operations department is working on ways to 3D-print aluminum, which would bring more efficiency to the production of Apple Watch casings and potentially one day iPhone enclosures.”
Apple’s interest in 3D-printed aluminum connects directly to its broader manufacturing strategy. The company wants to reduce raw material usage, improve production efficiency, and lower costs without sacrificing build quality.
For example, the recently introduced MacBook Neo uses a redesigned aluminum manufacturing process that focuses on minimizing metal usage. Apple says the laptop uses about 50 percent less aluminum compared with traditional production methods, which helps reduce cost while maintaining a durable chassis.
3D printing pushes that idea further because the process allows engineers to shape parts more precisely and avoid wasting excess material.
Benefits Apple already gained from 3D printing
Apple already uses 3D printing in several areas where traditional manufacturing methods create limitations.
Key advantages include:
- Reduced material waste, since printing uses only the metal required for the component
- Lower manufacturing costs through more efficient production methods
- Improved design flexibility, which allows engineers to create shapes difficult to forge
- Better structural bonding, such as the improved antenna housing design on cellular Apple Watch models
- Thinner components, including the USB-C port used in the iPhone Air
Engineers used 3D printing on the Apple Watch Ultra 3 to create textured internal surfaces that improve bonding between plastic and metal around the antenna housing. That change helped improve water resistance in cellular models.
Apple still needs to refine the aluminum printing process before it appears widely in consumer products. The Apple Watch will likely adopt the technology first, while the iPhone could follow later once the process scales for mass production.
