The Bambu Lab nozzle cleaner, also known as the nozzle wiper, is a flexible tool installed on the edge of the waste chute of the Bambu Lab 3D printers. The nozzle cleaner serves the crucial function of cleaning excess waste material that accumulates around the nozzle of the printer. Constructed with a PP elastic structure, a PTFE tube, and a lock screw, this cleaning tool is designed for optimal efficiency in maintaining a clean and smooth printing process. On the Bambu Lab Wiki the manufacturer provides a detailed guide on how to replace the nozzle cleaner.

When to replace?

The nozzle wiper must be replaced once the PP elastic structure experiences plastic deformation or breakage. Additionally, vigilance is required when dealing with the PTFE tube, as any looseness that permits rotation should be addressed promptly. To address this issue, users are advised to securely tighten the screws, ensuring that the PTFE tube remains fixed and cannot rotate. It's crucial, however, to exercise caution and avoid over-tightening to prevent slippage. In cases where slippage does occur, replacing the nozzle wiper becomes necessary to maintain the optimal functioning of the printer's nozzle cleaning mechanism.

HS Code	8477.9

Installation and positioning: the cleaner is usually installed at the edge of the waste chute or in the designated area of the printhead to allow the nozzle to pass through it before or after each job. Ensure that the fixing screw and PTFE tube are properly tightened to prevent play that could cause rotation or misalignment.

When to replace: replace the cleaner when the elastic PP structure is deformed or cracked, or if the PTFE tube shows excessive play when rotated; a worn cleaner will not properly remove residues and may affect print quality.

Nozzle maintenance and cleaning

Before each print: visually check for large residues around the nozzle; if present, perform a pre-cleaning to ensure uniform extrusion.
Supplementary cleaning: use soft tools such as silicone brushes or dedicated brushes to remove adhered material without damaging the hot tip; these help maintain nozzle cleanliness between prints.
Manual intervention if necessary: for minor internal blockages, use nozzle cleaning needles before performing a complete hotend removal.

Operational recommendations

Cut filament before starting: when loading material, cut the filament with a clean edge to prevent irregularities from being dragged into the nozzle.
Monitoring during printing: check if the nozzle drags material while moving; excess residues may require adjustment of retraction settings or more frequent cleaning.
Use appropriate brushes: to clean external and internal surfaces of the nozzle in detail during maintenance.
Avoid damage: do not use sharp metallic objects directly on the hot tip without protection, as this may deform or scratch the nozzle and affect extrusion quality.
Periodic cleaning around the hotend: remove accumulated residues from the waste chute or adjacent areas to prevent them from sticking to the next print.
