Robot Skeleton – Metal 3D-Printed Lightweight Monoblock

Facing challenges

Traditional CNC-machined robot skeletons require multiple assembly steps, resulting in heavy weight, poor rigidity, and the inability to incorporate internal cooling channels. The complex joint structure of six-axis robots is difficult to manufacture using conventional processes, leading to development cycles as long as 3-6 months.

Solutions

SLM metal 3D printing directly forms complex structural components such as robot joints and robotic arm skeletons, supporting various metals including mold steel, stainless steel, aluminum alloy, and titanium alloy. Topology optimization achieves weight reduction of over 40%. Integrated conformal cooling channels enhance heat dissipation efficiency. Joints are manufactured as single-piece parts, eliminating the need for assembly.

Achieve Results

Robot skeleton weight reduced by 45%, rigidity improved by 30%; internal conformal cooling channels enhance heat dissipation efficiency by 60%. Development cycle shortened from 3-6 months to 2 weeks. Successfully applied in 6-axis industrial robots, collaborative robots, and humanoid robot joints.
