The Ultimaker Feeder Ring is the original drive ring component of the filament feeder mechanism on Ultimaker 3D printers. The feeder ring provides the grip surface that engages the filament and drives it forward into the Bowden tube and hotend at a controlled, consistent rate. Over time and with high filament throughput, the ring's grip surface wears smooth, reducing traction on the filament and causing under-extrusion, filament slippage and inconsistent material flow.

Replacing the feeder ring with this genuine Ultimaker part restores the correct grip surface geometry, ensuring reliable, consistent filament feeding at the designed extrusion rate. This is a routine maintenance item for printers operating at high print volumes, and is one of the first components to inspect when under-extrusion or filament grinding is observed.

Key features

• Genuine Ultimaker OEM feeder ring for the filament drive mechanism.
• Restores correct grip surface for consistent, reliable filament feeding at the designed extrusion rate.
• Resolves under-extrusion and filament slippage caused by a worn, smooth feeder ring surface.
• Routine maintenance replacement after high filament throughput and extended print hours.
• First component to inspect and replace when under-extrusion or filament grinding is observed.

Compatible with: Ultimaker 2 series, Ultimaker 3 series (verify model with service documentation)
