On August 28, 2026, BLT (Bright Laser Technologies) disclosed that it 3D-printed the aluminum alloy hip joint for Honor's 'Lightning' humanoid robot using metal additive manufacturing. The component features closed cooling channels formed directly within the shell wall thickness, encircling the heat source. This design achieves structural-functional integration of heat exchange and load-bearing elements, balancing lightweighting with thermal management—real-world testing under half-marathon conditions kept the motor core temperature stable at 31–32°C. Manufacturing was carried out on BLT's in-house BLT-S600 system (build volume 650×650×850 mm, configurable with up to 16 lasers). At the Second World Humanoid Robot Games on August 23, Honor's 'Lightning' sprinted 100 meters in 9.32 seconds, reaching a peak speed of 14.5 m/s. BLT has also showcased robotic parts—including shoulder brackets, sternums, forearms, thighs, and finger joints—at the 2026 World Robot Conference, offering an end-to-end additive manufacturing solution. Value for powder buyers: ① Load-bearing components like humanoid robot hip joints open up new high-volume applications for aluminum alloy powders (AlSi10Mg/high-strength aluminum); ② One-piece forming with conformal cooling channels is becoming the mainstream design for robot joints, driving powder grade demand toward higher strength and lower defect rates; ③ BLT's full-chain case (equipment + materials + process) provides a validation template for domestic aluminum alloy powders entering the robotics supply chain.
