The Ultimaker Belts Pack (F Series) is the official OEM replacement belt set for Ultimaker F-series 3D printers, including the Factor 4. This pack contains all the drive belts required for the motion system - typically covering both the XY and potentially Z-axis drive belts - allowing a complete belt refresh in one convenient service pack. Drive belts are wear components: stretched or worn belts cause dimensional inaccuracies, ringing artefacts, and layer shifting, all of which degrade the print quality that Ultimaker F-series printers are designed to deliver.

Genuine Ultimaker belts are matched to the exact specifications of the F-series motion system, ensuring correct tooth profile, length, and tension characteristics for restored print precision.
