The UltiMaker Prefeeder Assembly is an OEM spare part for the UltiMaker Material Station (MS), the multi-filament feeder system used with the Factor 4 F Series industrial 3D printer. It handles the initial filament guidance and pre-feeding stage, moving filament from the spool compartment into the main feeder mechanism to begin the material transport path to the printer.

Reliable prefeeding is essential in a multi-material setup where filament must be loaded, unloaded and switched between materials without tangles, jams or missed feeds. A worn or damaged prefeeder assembly can cause misfeeds at the spool stage, leading to filament path errors that interrupt automated print runs. Replacing it with a genuine UltiMaker part restores the correct guidance geometry and drive action, keeping the Material Station operating reliably for unattended and production-critical workflows.

Key features

• OEM prefeeder assembly for the UltiMaker Material Station, providing correct filament guidance from spool to feeder.
• Ensures reliable filament pick-up and pre-feed action at the start of the material transport path.
• Critical for multi-material setups where consistent, automated filament loading and switching is required.
• Restores correct guidance geometry and drive force after wear, preventing misfeeds and path errors.
• Genuine UltiMaker part ensures OEM fit and compatibility with the Material Station feeder and housing.

Compatible with: UltiMaker Material Station (for use with Factor 4 / F Series)
