Apple tests 3D printing for producing its upcoming smartwatches: Report

Apple's supply chain and initiate a wider transformation. If the implementation with Apple Watches proceeds as intended, the technology company aims to extend this process to additional products in the coming years, adds the report. Those who do not know, the method employs a 3D printing method known as binder jetting to produce the device's initial outline, closely resembling its actual size, a manufacturing concept referred to as "near net shape." The printing is executed using a powdered material, which subsequently undergoes a sintering process involving heat and pressure to transform it into a material with the tactile properties of conventional steel.

Following this, the precise design and cutouts are milled, mirroring the steps in the previous manufacturing process. Apple, in collaboration with its suppliers, has been discreetly advancing this method for a minimum of three years. During the recent months, rigorous testing of the process has been conducted on steel casings intended for the upcoming Apple Watch Series 9, scheduled for unveiling on September 12.

It has been reported by Bloomberg that the forthcoming smartwatch will feature enhanced performance and introduce new case color options, while maintaining a largely consistent design. This endeavor represents one of the initial instances of employing binder jetting to scale up the production of a high-volume metal component. The decision to employ the Apple Watch as a trial platform for this emerging technology follows a consistent trend within the company.
