Bright Laser Technologies (BLT) has again contributed its metal additive manufacturing capability to support the manufacture of the hinge system for OPPO’s latest foldable smartphone.
Like the OPPO Find N5, the OPPO Find N6 smartphone features a flat, crease-minimised foldable display.
OPPO’s Find N6 smartphone launched globally in March 2026. The 3D printed hinge comprises wing plates on both sides that bear the majority of the folding stress. While traditionally a hinge system like this would be made up of up to 13 individual machined and assembled pieces, BLT is able to additively manufacture it as a single structure.
The additively manufactured part is said to exhibit increased strength and reduced weight thanks to the integration of lattice geometries.
“The supporting surface flatness of the OPPO Find N6 wing plate has improved by 50% compared to last year,” said Vincent Yang, General Manager at Bright Laser Technologies (Shenzhen) Co., Ltd. “Achieving this level of precision once seemed extremely difficult—even unattainable—but through continuous iteration and rigorous testing, our team was able to meet and even exceed expectations.”
OPPO Vice President and President of Hardware Engineering, Liu Chang, added: “Achieving a crease-free and durable foldable display depends not only on advanced technologies such as the next-generation titanium Tianqiong hinge and Tianqiong memory glass, but also on the collective efforts of the engineers within the Tianqiong Partners ecosystem. The Find N6 represents a significant step forward in foldable display technology, as well as a meaningful improvement in user experience.”
The collaboration was carried out as part of the “Tianqiong Partners” industrial alliance, initiated by OPPO to unite suppliers, research institutions, and other industry stakeholders. The alliance aims to address key technological challenges in foldable devices through joint development and knowledge sharing.
Through the combination of advanced manufacturing, engineering collaboration, and materials science, the OPPO Find N6 is said to have successfully passed 600,000 folding cycles certified by TÜV Rheinland.
