Flow Blocker - H2D

Bambu Flow Blocker — Nozzle Blocker for H2D

Reduce Standby Ooze • Cleaner Dual-Nozzle Prints • Faster Tool Changes

The Bambu Flow Blocker is designed specifically for the H2D dual-nozzle platform to suppress ooze from the inactive nozzle during printing. By mechanically shielding the idle nozzle tip, it helps prevent drips, color bleed, and stringing—resulting in cleaner seams, sharper transitions, and more reliable long prints.

Why use the H2D Flow Blocker

• Reduces standby ooze from the inactive nozzle
• Cleaner color and material transitions during tool changes
• Fewer strings, zits, and surface artifacts
• Helps maintain sharp edges and cleaner walls
• Simple drop-in installation—no firmware or slicer changes required

Ideal for

• Dual-nozzle H2D prints with frequent tool changes
• Multi-color parts and mixed-material workflows
• Soluble supports and interface-critical components
• Long prints where small leaks compound over time
