Compliance Evidence
⚠ Partially documented – evidence via manufacturer documentation under defined conditions. No complete FDA certificate on file.
Evidence: igus describes iglidur I150 as a food-safe filament on its igus food-safe page. No explicit EU 10/2011 or FDA 21 CFR certificate on file. Check the specific application, color and batch. Evaluate the printed part separately.
The evidence listed applies to the filament or raw material per manufacturer documentation. Regulatory clearance of the printed final product – particularly for food contact, medical devices, electrical applications or UL-relevant parts – is not automatically included and must be evaluated on a project-specific basis. Technical machine assignment is handled internally.
Material Documents
Material Profile
igus is the world market leader in plastic plain bearings. iglidur filaments bring this tribology expertise into FFF 3D printing: bearings and bushings that need no external lubrication because the lubricant is embedded in the polymer matrix.
How Do Self-Lubricating Tribo-Polymers Work?
iglidur materials contain firmly embedded solid lubricants (proprietary igus formula). Under frictional load, the material deposits a microscopic lubricating film on the mating surface:
- Lower coefficient of friction than an unlubricated standard polymer (~0.1–0.2 vs. ~0.4–0.6)
- Even wear instead of peak loads and cold welding
- Maintenance-free: no lubrication downtime in automated production
igus Tribo-Database
igus operates one of the world’s largest tribological test labs. For iglidur I150, documented PV values (pressure × velocity) are available for various mating materials – a unique design basis compared to generic FFF materials.
| Application | Recommended Bearing | Service Life (example) |
