How Often Should I Clean My Nozzle?

Honest answer: if you print the same material day in and day out, you don't need a regular 3D Clean schedule. Running some through during your general printer maintenance is fine, but it may not be necessary.

When to use it

• Every time you change material types through the same hotend, even just a little.
• When going from a sticky color to a light one.
• After filled or abrasive filaments.
• When you suspect a partial clog. See Spotting a partial clog.

Multi-toolhead printers

On printers like the Bambu Lab H2C, if each toolhead runs the same material every time, those toolheads rarely need purging. Use 3D Clean when you reassign a toolhead to a different material.

Cardboard spools

Cardboard spools shed dust, especially in an AMS where filament feeds and retracts constantly. That dust can end up in the hotend. A purge will often bring it out.
