The Ultimaker Bed Spring is the original compression spring used in the manual heated bed leveling system of Ultimaker 3D printers. The spring sits between the build platform base and the adjustment knob, providing the controlled resistance that allows precise manual bed leveling. Over time, springs can lose tension or become permanently compressed, making consistent bed leveling difficult and affecting first-layer adhesion.

Replacing worn bed springs with this genuine Ultimaker part restores the correct spring tension for reliable, repeatable manual leveling. This is a small but important maintenance item that significantly contributes to first-layer consistency, which is fundamental to print success for all materials and applications.

Key features

• Genuine Ultimaker OEM compression spring for the manual heated bed leveling system.
• Restores correct spring tension for precise and repeatable manual bed level adjustment.
• Prevents bed leveling drift and first-layer inconsistency caused by a weakened or collapsed spring.
• Small but critical maintenance component for consistent print start adhesion across the build area.
• Simple to replace as part of routine bed leveling maintenance.
