Filament for Bambu Lab: A1, P1S, AMS and profiles

Short answer

PLA, PETG and TPU work in both open-frame and enclosed Bambu Lab printers. Bambu Lab recommends ABS and ASA only for enclosed printers, such as the P1S, P2S, X1C and H2D. Standard TPU does not work in the AMS, and filament from other brands needs to be set up there manually. For most of our materials, you will find Bambu Studio profiles on the product pages.

Open-frame or enclosed printer?

This is how Bambu Lab groups its printers:

Open-frame printers A series (A1, A1 mini, A2L) and P1P

Enclosed printers P1S, P2S, X1 series, X2D and H2 series

PLA, PETG and TPU rarely lift at the corners and work in both types. ABS, ASA, PC and nylon (PA) need higher bed and chamber temperatures, otherwise the corners lift and the layers can separate. For these, Bambu Lab recommends an enclosed printer. Bambu Lab also recommends an enclosed printer for PETG, so that cold room air does not weaken layer adhesion.

ABS and ASA on the A1 and A1 mini

On the A1, Bambu Lab advises against printing large or high-infill models in ABS and ASA when they need strong layer adhesion. Small models with low infill can be printed, but only in a well-ventilated space at a safe distance from people. Bambu Lab does not recommend enclosing the A1.

On the A1 mini, Bambu Lab advises against ABS, ASA, PC and PA, and against filament filled with carbon or glass fibre. The A2L is made for PLA, PETG and TPU, and its bed reaches a maximum of 80 °C. TPU such as our 95A does not work in the AMS lite, so feed it from the spool holder.

Which filament for which printer?

Bambu Lab's advice by material type, not a test of our filament:

PLA (standard) Open-frame and enclosed. AMS and AMS lite. Does not cover glitter or fibre-filled PLA.

PETG (standard) Open-frame and enclosed, ideally enclosed. AMS and AMS lite. Does not cover fibre-filled PETG.

TPU 95A Open-frame and enclosed. Not in the AMS or AMS lite.

PVA (dry) Open-frame and enclosed. AMS and AMS lite.

ABS Enclosed printer recommended. Works in the AMS, but the AMS lite is not recommended.

ASA Enclosed printer recommended. AMS and AMS lite.

PCTG Not in Bambu Lab's table. Bambu Studio has a generic PCTG profile.

The AMS ratings apply only to loading and unloading, Bambu Lab notes. How much an abrasive filament wears down the AMS feed channels over time is not covered. You will find the materials here: PLA, PETG, PCTG, TPU, ABS, ASA and PVA.

Filament from other brands in the AMS

The AMS recognises Bambu Lab's own spools by their RFID tag. According to Bambu Lab, you set up filament from other brands yourself, either on the printer or in Bambu Studio:

On the screen: select the slot and enter the type and colour.
In Bambu Studio: click the edit icon next to the slot and choose the type and colour.
New spool in the same slot: the previous details stay until you change them.

Spools the AMS accepts, according to Bambu Lab:

AMS, AMS 2 Pro, AMS HT 50–68 mm wide, 197–202 mm in diameter

AMS lite 40–68 mm wide, centre hole 53–58 mm

All our filament is 1.75 mm, the diameter Bambu Lab specifies for its printers and the AMS. We do not state the dimensions of our spools, so measure the spool before you put it in the AMS. For cardboard spools, Bambu Lab strongly recommends an adapter ring so that the spool does not slip and leave debris in the AMS.

If a spool is outside these dimensions, as some larger spools are, feed it from the printer's spool holder. If it does not fit there either, Bambu Lab suggests an external spool holder, a dry box or a spool holder you print yourself.

Carbon fibre, glass fibre and hardened nozzles

Filament filled with carbon or glass fibre, such as nylon PA6-CF, wears down the nozzle. Bambu Lab says you should always use a hardened nozzle. Stainless steel and brass nozzles wear out quickly. The H2D Pro has a tungsten carbide nozzle, which, according to Bambu Lab, lasts even longer. Avoid a 0.2 mm nozzle, as the risk of clogging is very high. The first choice is a 0.6 mm hardened nozzle.

Pre-installed nozzle, according to Bambu Lab:

Stainless steel A1, A1 mini, A2L, P1P, P1S

Hardened steel X1C, X1E, P2S, X2D, H2D, H2S, H2C

Tungsten carbide H2D Pro

On the P1P and P1S, Bambu Lab recommends a hotend with a hardened steel nozzle and a hardened steel extruder gear before you print carbon fibre. If you switch to a different type of nozzle, update the nozzle information on the screen before printing.

Bambu Lab's table lists PETG-CF and ABS-GF as compatible with the AMS but not recommended for the AMS lite. The table only covers loading and unloading. In its guidance on the AMS and AMS lite, Bambu Lab advises against fibre-filled filament from other brands, and the AMS 2 Pro does not support it. So feed our fibre-filled filaments from the spool holder. Our PLA, PETG, ABS and ASA with carbon or glass fibre do not have a profile of their own. The product page shows the profile for the base material.

Bambu Lab's nozzle advice also mentions particle-filled PLA, such as its PLA Marble and PLA Sparkle, but the table does not require hardened steel for PLA Marble. We have not measured how abrasive our marble PLA or our glitter filaments are. If you print a lot with them, a hardened nozzle is the cautious choice.

The A1, A2L, X1C, X1E, P2S, X2D, H2D, H2S and H2C already have hardened steel extruder gears. You will find the Hardened Steel Extruder Gear for Bambu Lab among our accessories. Ask us if you are unsure whether it fits your model.

Temperatures for our filament

If you set the temperature yourself, go by the ranges we give:

PLA Nozzle 190–220 °C (PLA Pro 180–220 °C), bed 40–65 °C

PETG Nozzle 220–255 °C, bed 50–70 °C

PCTG Nozzle 240–260 °C, bed 70–80 °C

ABS Nozzle 230–260 °C, bed 90–110 °C

ASA Nozzle 230–265 °C, bed 90–110 °C

TPU 95A Nozzle 200–230 °C, bed 25–75 °C

TPU 70D Nozzle 230–260 °C, bed 50–80 °C

Printing PLA, PVA or TPU in an enclosed printer with the bed above 45 °C? Then Bambu Lab recommends opening the door or removing the glass lid. Otherwise the material can soften in the extruder, especially in a warm room. The same advice applies to PETG when the bed is above 60 °C.

For more settings, see the printing guides for PLA, PETG, ABS, ASA and TPU.

Our profiles for Bambu Studio

You will find profiles for Bambu Studio under Downloads on our product pages. They apply to every colour in the material line. We have none for nylon, PC, HIPS or PBT, and for PEBA only a .3mf file with a test print.

PLA (including PLA Pro), PETG, PCTG, ABS, ASA and TPU: a .bbsflmt file, which you import into Bambu Studio with the Import Presets feature (the menu names are from the English version of Bambu Studio).
PETG Matt and PVA: a .3mf project file made on an H2D with a 0.4 mm nozzle, with the settings stored in the project. The PVA file is based on Bambu Lab's own PVA profile.

Each .bbsflmt file contains one profile per printer and nozzle size: A1, A1 mini, P1P, P1S, P2S, X1, X1C, X1E, X2D, H2C, H2D, H2D Pro and H2S. ABS and ASA have no A1 mini profile, PCTG and TPU have no 0.2 mm profile, and the A2L is not included. The profiles are based on Bambu Lab's generic profiles, with our adjustments.

You can assign custom filament profiles to a slot under the Device tab in Bambu Studio. They are then synced to the printer and Bambu Handy, according to Bambu Lab. Run flow calibration in Bambu Studio on your own printer, as the notes in the profiles say. On the X2D, the profiles for the secondary nozzle are not calibrated, so run your own calibration before printing with it.

Do you have an A2L, a printer other than the H2D for PETG Matt and PVA, or a material we have no profile for? Then choose Bambu Lab's generic profile for the material, for example Generic PETG. These are good enough for most prints, according to Bambu Lab.

Drying in the AMS 2 Pro and AMS HT

The AMS 2 Pro dries at up to 65 °C and the AMS HT at up to 85 °C, and only when they are connected to the printer. Bambu Lab's drying settings:

PLA 45 °C for 12 h

PETG 65 °C for 12 h

ABS and ASA 80 °C for 8 h (AMS HT)

TPU 75 °C for 12 h (AMS HT)

PVA 85 °C for 18 h (AMS HT)

Bambu Lab does not recommend the AMS 2 Pro for ABS, ASA, TPU or PVA. If you are drying higher-temperature materials such as PETG or ABS, take PLA and TPU out of the AMS first, otherwise they can soften. A spool that has not been set up shows as “?” and is dried as PLA, so set the material first.

The AMS HT dries using its own power cable. On the X1 and P1 series and the A2L, each AMS 2 Pro needs its own power adapter to dry. The H2 series, P2S and X2D can power one AMS 2 Pro for drying, but each additional AMS 2 Pro needs its own power adapter.

Frequently asked questions about filament for Bambu Lab

Which filament works with the Bambu Lab A1 and A1 mini?

PLA, PETG, TPU and PVA. According to Bambu Lab, you can print small, low-infill models in ABS and ASA on the A1, but only in a well-ventilated space at a safe distance from people. On the A1 mini, Bambu Lab advises against ABS and ASA. Feed TPU such as our 95A from the spool holder, not through the AMS lite.

Which filament works with the Bambu Lab P1S and P2S?

PLA, PETG, TPU, ABS and ASA. Both are enclosed printers, and Bambu Lab recommends an enclosed printer for ABS and ASA. Feed our TPU from the spool holder, not through the AMS. For carbon fibre on the P1S, Bambu Lab recommends a hotend with a hardened nozzle and a hardened steel extruder gear. The P2S comes with both factory-fitted.

Can I use filament from other brands in the AMS?

Yes, if the material works in the AMS according to Bambu Lab's table. You set the type and colour yourself, on the screen or in Bambu Studio. The spool should be 50–68 mm wide and 197–202 mm in diameter, and for the AMS lite 40–68 mm wide with a centre hole of 53–58 mm. Bambu Lab advises against standard TPU and against fibre-filled filament from other brands in the AMS.

Can TPU be used in the AMS or AMS 2 Pro?

Not standard TPU such as our 95A. According to Bambu Lab, it does not work in the AMS, the AMS lite or the AMS 2 Pro. The AMS HT cannot feed TPU automatically, but you can dry and store TPU in it. For our harder TPU 70D we have no AMS data, so feed it from the spool holder.

Do I need a hardened nozzle?

Not for standard PLA, PETG, ABS, ASA or TPU, according to Bambu Lab's table. For filament filled with carbon or glass fibre, Bambu Lab says you should always use a hardened nozzle. If you print a lot with marble or glitter filament, a hardened nozzle is the cautious choice.

Are there Bambu Studio profiles for PrintOnion filament?

Yes, for PLA, PETG, PCTG, ABS, ASA and TPU. For PETG Matt and PVA there is a .3mf project file made on an H2D. You can download them under Downloads on the product page. Import the profile file (.bbsflmt) into Bambu Studio with Import Presets.

Can I enclose my A1 to print ABS?

Bambu Lab does not recommend enclosing the A1. For ABS and ASA, Bambu Lab recommends an enclosed printer instead.
