Apple’s shift to 3D Printing’s smartwatch manufacturing

Posted on

Apple is embarking on a groundbreaking journey into 3D printing technology, with plans to incorporate it into the manufacturing of its smartwatches. This innovative approach has the potential to reshape how the tech giant produces its products, creating a more efficient and environmentally friendly process. Apple has relied on a conventional method for crafting the steel chassis of its stainless-steel smartwatches, which constitute a notable portion of its product lineup. This involved forging bricks of material into a smaller metal block, which was then meticulously cut into the desired design and buttonholes using computer numerical control (CNC) machines.

The new technique, however, leverages a 3D printing method known as “binder jetting.” It starts by creating a near-net shape of the watch’s general outline, close to its actual size, using powdered material. Subsequently, a process called sintering is employed, using heat and pressure to transform the powdered substance into a steel-like material. The final step involves precise milling to craft the design and cutouts, similar to the previous manufacturing process. This initiative, developed over three years in collaboration with Apple’s suppliers, has recently undergone testing with steel cases intended for the upcoming Apple Watch Series 9. While it’s uncertain whether the first consumer shipments will employ this novel technique, these trials underscore Apple’s dedication to exploring innovative manufacturing approaches.

The potential benefits are twofold: reducing environmental impact and simplifying production. By using only the necessary amount of metal to create device enclosures, this approach aligns with Apple’s sustainability efforts. Additionally, Apple intends to replace leather with alternative materials in some iPhone cases and accessories, furthering its commitment to eco-conscious practices. Apple’s manufacturing design team, under the leadership of Vice President Rob York and reporting to Operations Head Sabih Khan, spearheads the 3D printing endeavor. Although the transition to 3D-printed watch cases is a substantial investment for Apple and its suppliers, it promises long-term cost reductions and production streamlining.

While the current focus is on lower-volume products, such as stainless-steel watch cases, Apple is exploring the possibility of extending 3D printing to materials like steel and titanium for various devices. This move exemplifies Apple’s penchant for adopting cutting-edge technology and integrating it into its product lineup, a pattern we’ve seen in the past with innovations like steel frames on iPhones and the use of titanium in high-end Apple Watches. In essence, Apple’s foray into 3D printing marks an exciting chapter in the company’s manufacturing evolution, with the potential to revolutionize not only smartwatch production but also its broader product range.
