Guo Mingchi pointed out that the screen size of Apple Watch Series 10 will become larger and thinner. Starting from the second half of this year, Apple Watch will begin to use components produced by 3D printing technology. Although there was no mass production at the end of last year, after more than a year of intensive testing, the production efficiency of 3D printing has significantly improved. The supplier of 3D printed components is Xi'an Bright Laser Technologies. Unlike before, Xi'an Bright Laser Technologies was a equipment supplier last year, but a component manufacturer this year. Guo Mingchi expects that Xi'an Bright Laser Technologies' 3D printed components will continue to grow in shipments and have the opportunity to become the shell of Apple Watch in the next few years due to cost advantages of 3D printing.
