The Ultimaker Sliding Block Pack for UM3 and 2+C is an OEM spare parts pack containing sliding blocks sized for the Ultimaker 3 and Ultimaker 2+ Connect 3D printers. Sliding blocks are the friction-fit components that guide printhead travel along the XY cross rods. As a wear item, they gradually loosen over time, introducing play in the printhead that reduces dimensional accuracy, causes ghosting and can eventually lead to layer shifting on high-speed or complex prints.

Replacing sliding blocks on the UM3 or 2+C is a standard maintenance procedure that brings XY motion back to factory tolerance and restores print quality. The UM3 and 2+C share the same sliding block specification, making this pack the correct choice for both models. Use the model-specific packs for S5/S7/S8 (210000007272), S3 (210000007273) or UM2 (210000007271) if you have a different Ultimaker model.

Key features

• OEM sliding blocks dimensioned correctly for the Ultimaker 3 and Ultimaker 2+ Connect XY rod geometry.
• One pack covers both UM3 and 2+C, which share the same sliding block specification.
• Restores factory-tolerance XY motion precision to eliminate ghosting, ringing and dimensional inaccuracy.
• Genuine Ultimaker parts maintain full mechanical compatibility with the UM3 and 2+C motion system.
• Standard service item recommended whenever printhead XY play is identified during maintenance or quality inspection.
• Also available for UM2 (210000007271), S5/S7/S8 (210000007272) and S3 (210000007273) for other Ultimaker models.
