AMS

Which filaments work in the Bambu AMS?

First in this ranking: Polymaker Polylite PLA.

Nozzle190–230 °C
Bed25–60 °C
Speed40–60 mm/s
Dry55 °C for 6 h
Density1.17 g/cm³

Ranked filaments

Rank	Filament	Material	Nozzle	Bed	Price / kg	Datasheet	Retailer
1	Polymaker Polylite PLARigid PLA with a listed nozzle of 190–230 °C. The kind of spool the consensus says the AMS can run.	PLA	190–230	25–60	Not listed	Datasheet	Not configured
2	Prusament PETGRigid PETG with a listed nozzle of 240–260 °C and a datasheet. Still a normal AMS material in this consensus.	PETG	240–260	70–90	Not listed	Datasheet	Not configured
3	Bambu Lab PLA BasicBambu’s own PLA Basic. The record has a datasheet and does not list nozzle or bed temperatures.	PLA	190–230	35–45	Not listed	Datasheet	Not configured
4	Bambu Lab TPU for AMSThe exception, not the default. Ordinary TPU stays out. This SKU is named for the AMS, has a datasheet, and does not list a nozzle range.	TPU	Not listed	Not listed	Not listed	Datasheet	Not configured

When to use which material

Load rigid PLA and PETG. Leave ordinary TPU for the TPU guide, printed from the spool holder on a direct drive. Leave very brittle carbon fiber out of the AMS even if the printer has a hardened nozzle. TPU for AMS is the named exception and it does not list temperatures.

Temperatures and settings

PolyLite PLA lists 190–230 °C. Prusament PETG lists 240–260 °C. PLA Basic and TPU for AMS do not list nozzle or bed temperatures, so those cells stay blank. Dry hygroscopic spools before they sit in the AMS. Moisture is the drying problem, and a sealed AMS is not a dryer.

Failure modes

TPU buckles in the AMS feed path. Brittle CF snaps. A cardboard spool slips or sheds dust into the feeder. The consensus fix for cardboard is an adapter or respooling, not a different PLA. A stainless nozzle on a P1S is a second reason to keep abrasive CF out, separate from the brittleness rule.

Caveats

Adapters are not in the filament catalog. Do not invent a brand of ring. The AMS field on a printer page is the hardware note. It is not a list of approved filaments.

Where this sits in the catalog

P1S and P1P list AMS. X1 Carbon lists AMS as optional and a hardened nozzle. A1 and A1 mini list AMS lite. PolyLite PLA on the P1S is that settings page. Bambu Lab is where PLA Basic and TPU for AMS live.

Pros and cons

Pros

Rigid PLA and PETG are the uneventful AMS load, and both have catalog rows with temperatures.
TPU for AMS is a real product name, so the exception is a record instead of a rumor.

Cons

Spool adapters are not filaments. There is no adapter SKU to link.
PLA Basic and TPU for AMS do not list nozzle temperatures. The pages say Not listed rather than copying another PLA.

Printer considerations

P1P and P1S list AMS. X1 Carbon lists AMS as optional. A1 and A1 mini list AMS lite, and a full AMS needs the hub those pages describe.
P1S records a stainless nozzle. Brittle or abrasive CF is a bad AMS citizen and a bad match for that nozzle.
X1 Carbon records a hardened nozzle. That does not put brittle CF back on the AMS list. The consensus still says to avoid very brittle CF.

Printer limits

What the community says

The consensus is that the AMS handles most rigid filaments, and that you should avoid TPU, very brittle carbon fiber, and bare cardboard spools. Cardboard wants an adapter or a respool. The products named are the Bambu AMS and spool adapters.

Questions

Can I run Prusament TPU 95A from the AMS?

No. Ordinary TPU is on the avoid list. The catalog row named TPU for AMS is the exception, and even that row does not list a nozzle temperature.

Does a plastic side plate make cardboard acceptable?

The consensus says bare cardboard is the problem, and the fix it names is an adapter or respooling. This database does not stock adapters, so it cannot name a model.
