3pcs Filament Cutter for Bambu Lab X1/P1/A1

Description

Replacement Filament Cutters for Bambu Lab X1, P1 & A1

The filament cutter on your Bambu Lab printer is a small component that does critical work — it trims the filament tip cleanly after each retraction and colour change so the next feed enters the hotend smoothly. When the cutter blade dulls or wears, you get ragged filament tips that cause jams, failed AMS feeds, and wasted filament. This 3-pack gives you fresh, sharp replacement blades to keep your printer feeding reliably.

At $6.49 for three, it’s one of the cheapest and most effective maintenance items you can keep on hand.

Why Clean Filament Cuts Matter

A sharp cutter produces a clean, angled filament tip that feeds through the PTFE path and into the hotend without catching or jamming. A dull cutter leaves behind a crushed, frayed, or mushroomed tip that can snag in the feed path, cause the AMS to fail a filament load, or create a partial clog at the hotend entrance.

This is especially noticeable in multi-material and multi-colour prints where the cutter activates repeatedly throughout the print. The more colour changes per print, the faster the blade wears and the more important it is to replace it regularly.

When to Replace

There’s no fixed replacement interval — it depends on how many filament changes your printer processes. Signs that your cutter is due for a swap include AMS feed failures that weren’t happening before, filament tips that look crushed or frayed instead of cleanly cut, increased stringing at the start of new colour segments, and jams during filament loading.

With three cutters in the pack, you can keep spares ready and swap one in as soon as you notice any of these symptoms.

Compatibility

These filament cutters are compatible with the Bambu Lab X1 Carbon, P1P, P1S, A1, and A1 Mini. They work with all standard 1.75 mm filaments including PLA, PETG, ABS, ASA, TPU, and carbon fibre composites.
