3D-printed titanium alloy interlocking unit
This product is a metal 3D-printed titanium alloy interlocking unit, demonstrating its potential application in watch strap designs.
Based on previously available data, the component weighs only around 50 g, with each unit cell measuring approximately 1.2 mm × 1.2 mm × 2 mm. This self-supporting structure enables the flexible lattice to achieve micron-level printing precision.
The shiny surface finish suggests that the part has undergone post-processing such as grinding and polishing, and possibly electroplating as well.
Titanium alloy watch strap
This product is a 3D-printed metal watch strap, measuring 22 mm × 2.05 mm × 99.14 (80.75) mm. It is made of titanium alloy, with a single strap weighing approximately 40 g.
The strap was produced on a BLT-A160 3D printer, with a layer thickness of 30 μm, and a single-piece printing time of about 51 minutes.
Technical specifications indicate that the product achieves integrated flexible-structure printing, surpassing the limitations of traditional machining. Equally important, it maintains a tensile strength of 2000 N while reducing weight by approximately 50% compared to conventional stainless steel straps, significantly improving wearing comfort.
Titanium alloy offers excellent biocompatibility and corrosion resistance, and combined with the unique fine sandblasted texture achievable via 3D printing, the strap provides a skin-friendly feel while maintaining a sense of functional aesthetics.
Folding phone hinge shaft cover
This product is a shaft cover within the hinge structure of an OPPO folding phone, measuring 164 mm × 6.5 mm × 4.5 mm and made via titanium alloy 3D printing, with a single unit weighing 6 g.
It was manufactured on a BLT-S400 3D printer, with a layer thickness of 35 μm and an average production time of about 2 minutes 30 seconds per piece.
Technical specifications indicate that the Laser Powder Bed Fusion (LPBF) 3D printing process overcomes the limitations of traditional CNC machining for thin-walled parts (<0.2 mm), enabling the creation of ultra-thin, high-rigidity, asymmetric curved structures.
Folding phone hinge wing plate
This product is the folding hinge wing plate of the OPPO Find N5, measuring 156 mm × 8 mm × 2 mm (including the sliding groove) and produced via titanium alloy 3D printing, with a single piece weighing 1.8 g.
Technical specifications indicate that it was manufactured on a BLT-A160 3D printer, with a layer thickness of 30 μm and an average production time of approximately 2 minutes 45 seconds per piece. The high-precision Laser Powder Bed Fusion (LPBF) 3D printing process enables integrated formation of the wing plate and sliding groove, even with extremely thin, variable cross-section structures, achieving significant weight reduction while maintaining equivalent bending strength.
Both the hinge shaft cover and the wing plate are titanium alloy 3D printed. The material’s high strength greatly enhances resistance to deformation under complex stresses, while LPBF-printed parts also exhibit excellent post-processing and surface finishing properties, offering wear resistance, drop resistance, and premium tactile quality.
This product is a monolithic aluminum alloy eyeglass frame manufactured via 3D printing.
This eyeglass frame measures 141mm × 48mm × 25mm and is 3D printed from aluminum alloy using a BLT-A320 printer, with a single piece weighing approximately 42g.
Metal 3D printing enables monolithic manufacturing, with a layer thickness of 30 μm and an average production time of about 3 hours. In contrast, traditional manufacturing would require multiple steps, including cutting, finishing, and welding, making 3D printing much faster.
Additionally, the aluminum alloy used can undergo anodizing with excellent results. The material has a room-temperature tensile strength of 300 MPa and an elongation of 10%, providing a combination of strength, aesthetics, and lightweight performance.
watch case
This product demonstrates the transformation of a watch case from its 3D-printed blank to the final product. The product dimensions are 12.5 mm × 47.4 mm × 54.4 mm, made using titanium alloy 3D printing, with a single piece weighing approximately 19.2 g.
According to technical specifications, the manufacturing equipment used is a 6-laser BLT-S400, with a layer thickness of 30 μm, and an average single-piece manufacturing time of only 10 minutes. Metal 3D printing enables the integrated formation of the watch case’s complex structure, significantly reducing steps compared to traditional manufacturing, while maintaining the mechanical strength and dent resistance of conventional processes. It also supports fine finishing such as mirror polishing. Based on the single-piece manufacturing time and structural complexity, this product is well-suited for rapid batch production.
