Apple Testing 3D Printing to Manufacture Smartwatch Components, Aiming for Sustainability and Efficiency
Apple is reportedly experimenting with 3D printing technology to manufacture the metal chassis for some of its upcoming Apple Watch models, potentially marking a major shift in how the tech giant builds its devices.
A Move Toward More Efficient and Eco-Friendly Manufacturing
According to sources familiar with the matter, Apple is adopting a technique that eliminates the need to carve metal blocks into shape. This change could significantly reduce production time and material waste, contributing to Apple’s long-term sustainability goals.
The new method could also streamline Apple's global supply chain. If successful, the company may expand the process to include more products over the coming years. Apple has yet to officially comment on the development.
How the 3D Printing Process Works
Apple’s current manufacturing method involves forging – shaping large metal blocks, followed by CNC (computer numerical control) machining to carve out precise designs and button placements.
The new technique uses a 3D printing process known as binder jetting. Here’s how it works:
-
A powdered material is printed into a near-final shape (called “near net shape”).
-
The printed structure is then sintered, a process using heat and pressure to form a solid metal object.
-
Final refinements, such as cutouts and design detailing, are added using traditional milling techniques.
Impact on Apple Watch and Future Devices
Apple has been working on this technology for over three years, with recent testing focused on stainless steel cases for the Apple Watch Series 9, which is expected to launch at the Apple 'Wonderlust' event on September 12, 2025. While it’s unclear if the first batch of watches will include 3D-printed parts, the testing phase suggests Apple is committed to the process.
Apple also plans to apply this technique to the Apple Watch Ultra’s titanium case, though that transition is not expected until 2026.
Environmental and Economic Benefits
The 3D printing approach offers several advantages:
-
Reduces metal waste, using only the necessary amount of material.
-
Lowers carbon footprint, aligning with Apple’s broader environmental goals.
-
Could eventually reduce production costs, though current costs are on par with traditional methods.
In addition to 3D printing, Apple is exploring sustainable material alternatives to leather in iPhone cases and other accessories, reinforcing its commitment to eco-conscious innovation.
Technology Still in Early Stages
For now, the new 3D printing method will be limited to low-volume production. Most Apple Watch cases are made from aluminum, a material not yet suitable for Apple’s 3D printing plans. However, discussions are ongoing about using 3D-printable materials like stainless steel and titanium in other Apple devices, including Macs, iPads, and higher-end iPhones.
This initiative marks one of the first major uses of binder jetting for high-volume metal component production. Apple has a history of testing new materials and technologies on the Apple Watch before bringing them to other products — such as the shift to titanium frames on this year’s iPhones following their debut on the Apple Watch Ultra.
