Bambu Lab Filament Guide: Types, RFID Spools and Third-Party Options

Bambu Lab sells its own filament in a wide range of materials, with RFID tags that let its AMS recognize each spool automatically. You can also use third-party filament, with some manual setup. This guide covers what Bambu Lab makes, what its documentation says about temperatures, nozzles and the AMS, how RFID spools work, and what to check before buying other brands.

This is a research article. It is based on Bambu Lab's wiki and store pages (listed in the sources), plus a Polymaker product page, not on our own printing. Prices are from Bambu Lab's UK store, checked on 2026-10-10. Bambu Lab's US store address redirected to the UK store when checked, so prices below are in pounds.

The short answer

• Start with PLA Basic (or PLA Matte). At £16.99 per 1 kg spool, or £13.99 as a refill, it is the base of the range.
• Use PETG HF when a part needs more toughness or heat resistance, and ABS or ASA on an enclosed printer.
• Carbon fiber filaments (PLA-CF, PA6-CF, PET-CF) need a hardened steel nozzle, per Bambu Lab's guidance.
• Official spools are recognized by the AMS through RFID. Third-party spools work, but you set the filament type and color yourself.

Bambu Lab filament types and prices

The table lists Bambu Lab's filaments as sold in its UK store on 2026-10-10, with the nozzle temperature range from Bambu Lab's filament guide. The temperature range is a guide for the Bambu Lab profile, with a tolerance of about 10 °C; the label on your spool and the slicer profile come first.

Colors and stock vary, and Bambu Lab also sells silk, translucent, glow and other specialty lines not covered here. For the money side across brands, see how much filament costs.

Which Bambu Lab filament for which job

PLA Basic and PLA Matte

Bambu Lab's beginner guide calls PLA the best choice if you are just getting started, with predictable results, and gives a print range of 190 to 230 °C. Its material table lists a wider 190 to 240 °C for PLA. Use PLA for models, prototypes and indoor parts. It is the cheapest option and the least fussy. See PLA print temperature for how to tune it.

PETG HF

PETG offers better heat resistance than PLA, and Bambu Lab lists PETG HF as a high-flow version with a 230 to 260 °C range. Its wiki recommends an enclosed printer for PETG so low ambient temperature does not reduce interlayer strength. See PETG vs PLA and what is PETG.

ABS and ASA

Bambu Lab says ABS, ASA, PC and PA materials need an enclosed printer, because higher bed and chamber temperatures suppress warping and layer separation. Its beginner guide says ABS is moderately superior to PLA but prone to warping without a hot bed, and not food safe. Compare them in ASA vs ABS and ABS vs PETG. Open-frame models are discussed in A1 vs A1 mini.

TPU for AMS

Flexible filament is difficult in an AMS. Bambu Lab's wiki says to avoid TPU, TPE and absorbent PVA in the AMS because they can get stuck in the feed tube, while its table lists TPU for AMS as compatible with the AMS. Read the TPU page for your model before loading flexible filament, and see what is TPU.

Carbon fiber filaments

For carbon fiber or glass fiber filled materials, Bambu Lab says always use a hardened steel nozzle, and avoids stainless steel or brass nozzles because they wear quickly. For its own filaments such as PLA-CF and PETG-CF it highly recommends a 0.4 mm hardened steel nozzle. It also recommends a 0.6 mm hardened steel nozzle as the first choice for most such materials, with lower clogging risk. See hotends and nozzle materials and nozzle sizes explained.

RFID spools and the AMS

Bambu Lab's AMS reads an RFID tag on official spools. Its setup page says that with an official spool, the AMS automatically identifies the type and color of the filament, and you can tap the slot to view the details but cannot change them. With an unofficial spool, you configure the filament information on the printer screen, or in Bambu Studio, and the slot keeps that information until you change it.

Other points from Bambu Lab's AMS notes:

• The AMS supports spools with a width of 50 to 68 mm and a diameter of 197 to 202 mm.
• Bambu Lab recommends its own filament, which it says has been thoroughly tested with the AMS.
• Plastic spools that fit correctly are strongly preferred. For cardboard spools, use a spool adapter or adapter ring to reduce slippage and debris.
• Avoid flexible filament (TPU, TPE) and soft or absorbent PVA in the AMS.
• Avoid very hard or brittle filaments, including third-party fiber-reinforced ones, because they may wear the AMS PTFE tubes or snap. Bambu Lab says its own PLA-CF, PETG-CF and PAHT-CF are tuned to avoid this.
• PTFE tubes are consumables. Check them for wear during maintenance.

The AMS lite is more limited than the AMS. Bambu Lab says PETG-CF and PLA Wood work in the AMS but are not recommended for the AMS lite.

Using third-party filament on a Bambu Lab printer

Nothing stops you from using other brands. The practical points are:

1. Set the filament manually. Pick the closest material and color on the printer screen or in Bambu Studio, as above.
2. Check the spool. It must fit the AMS dimensions. Polymaker states that all its spools now have hardened edges that roll well in the AMS.
3. Match the profile to the label. Use the temperature range printed on the spool, because Bambu Lab's profiles are tuned to its own filament.
4. Avoid risky materials in the AMS. Feed flexible or abrasive filament from the spool holder, not the AMS, where your printer supports it.
5. Use a hardened nozzle for filled filaments, regardless of brand.

Cardboard spools, thin flanges or loose winding are the most common reasons a third-party spool fails to feed. If you are comparing brands on price and quality, read cheap vs premium filament.

Reusable spools and refills

Bambu Lab sells many filaments as a refill without a spool, which in its UK store is £3.00 cheaper for PLA Basic. Its wiki describes a reusable spool design that cuts plastic waste in feeding by at least 20%. There are two types: a low-temperature spool rated to 70 °C, compatible with PLA and PETG, and a high-temperature spool rated to 90 °C, compatible with PLA, PETG, ABS, ASA, PA6-GF, ABS-GF, PAHT-CF, PET-CF, PA6-CF, PC and TPU. Match the spool to the material, especially if you plan to dry it.

Storage and drying

Bambu Lab says all filaments absorb moisture to some degree, and recommends drying before printing if you are unsure of storage conditions, then keeping filament sealed with desiccant. Its table suggests, in a blast drying oven, 55 °C for 8 hours for PLA, 65 to 70 °C for 8 hours for PETG, 80 °C for 8 hours for ABS and ASA, and 70 °C for 8 hours for TPU. It lists PETG HF as requiring desiccant protection during use. Bambu Lab also notes that open-frame printers (P1P, A1, A1 mini, A2L) cannot be used to dry filament on the bed.
