On June 17th, the 3D printing concept of A-share market boosted.

On the news front, well-known analyst Ming-Chi Kuo just posted on X, stating that the focus of attention for the new Apple Watch in 2H24 is Series 10, Bright Laser Technologies/3D printing. Kuo pointed out that Apple Watch will start using components produced by 3D printing technology from 2H24. 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 been significantly improved. The supplier of 3D printed components is Bright Laser Technologies. Unlike before, Bright Laser Technologies was a device supplier last year and a component manufacturer this year. Due to the cost advantage of 3D printing, it is expected that Bright Laser Technologies' 3D printing components will continue to grow in shipments in the next few years and have the opportunity to achieve the Apple Watch case (because the difficulty of the Apple Watch case is lower than that of other Apple products).
