The Ultimaker Left Feeder Assembly is an OEM service part for the S3, S5 and S7 dual-extrusion 3D printers, responsible for controlled, consistent filament feeding on the left material path. The feeder works together with the Bowden tube and print core system to deliver precise material flow under varying print conditions.

Replace the feeder assembly when experiencing under-extrusion, slipping, or grinding on the left extruder. Using a genuine Ultimaker part ensures correct grip geometry and feed force, preventing calibration drift caused by worn or incompatible feeders.
