A 3D‑printed bearing design that requires no additional assembly and is produced in a single, integrated print—breaking free from the assembly constraints of traditional bearings while seamlessly combining the ingenuity of mechanical design with the convenience of 3D printing.

- Key Highlights
​
1. One‑piece Design: The entire component is 3D printed in a single build, eliminating the need for post‑print assembly of individual parts such as balls, inner rings, or outer rings—resulting in a finished product straight out of the printer.
​
2. Smooth, Free‑Rotating Motion: Featuring an integrated, rolling ball mechanism, this design delivers rotational performance comparable to conventional bearings.
​
3. Full‑Size Customization: Users can adjust the inner and outer diameters, wall thickness, and ball size to perfectly match their specific application requirements, making it ideal for a wide range of scenarios.
