Apple plans to begin manufacturing accessories and parts of its devices using 3D printing, to speed up manufacturing processes and improve sustainability.

According to a new report by Bloomberg, Apple will begin using 3D printing to manufacture the body of its new smart watch, the Apple Watch 9, which is expected to be launched during the annual ceremony scheduled this september, at the Steve Jobs Theater at its Apple Park headquarters in the US state of California.

The new system will save a large percentage of metal when manufacturing device bodies, because the company will print the exact size of the frame it needs, instead of having to cut huge sheets of the required metal, thus reducing the percentage of waste.

Manufacturing processes require high-quality metals such as stainless steel and titanium, so Apple is experimenting with 3D printing for the first time this year with its “Apple Watch 9” made of steel.

Apple aims to expand its efforts in this field, to include a highly capable version of its smart watches, “Apple Watch Ultra,” by next year.

The report suggests the possibility of introducing 3D printing into the production of its smart devices, including iPhones and iPads.

Bloomberg had expected, in a previous report, that the Apple Watch 9 would be offered in the same sizes as the previous versions, which are 41 and 45 millimeters, in addition to a new version in the size of 49 millimeters, with the processor chip updated and new colors added.

The new method of manufacturing Apple Watches may coincide with the imminent launch of an exceptional version called “Apple Watch

The company also seeks to replace the traditional design of its watch bracelets with a magnetic system, as it will provide a large area of the structure that can be used to add components such as a battery with a larger capacity, or sensors to develop the capabilities of the watch.
