Best Filament for the Bambu Lab P2S (2026)

Quick picks

These are defaults by need, not a ranking.

Who this page is for

This page is for owners of a Bambu Lab P2S or P2S Combo, with or without an AMS, who want to know which spools suit the printer before buying. Bambu's spec page lists a 1.75 mm filament diameter, and every spool here is 1.75 mm. For nozzles, hotends and build plates that fit, see the P2S printer page. If you own a P1S or P1P instead, see our P1S and P1P filament page. Bambu's P2S FAQ says the P1S can't be upgraded to a P2S, and many parts differ between them, so don't assume P1S advice carries over.

The table is grouped by material, not ranked. The last four are carbon-fiber filaments, which the P2S can run on its stock nozzle.

What can the P2S print, per Bambu?

Hardware. Bambu's P2S spec page and FAQ list these limits:

Materials. Bambu's spec page lists these supported filaments: "PLA, PETG, ABS, ASA, TPU, Support for PLA, Support for PLA/PETG, Support for ABS, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF." Bambu's filament guide names the P2S among the enclosed printers it recommends for ABS, ASA, PC, PA and their fiber-reinforced versions, which "require higher heatbed and chamber temperatures to suppress warping and layer separation."

Temperatures. Every spool on this page has a published nozzle range that tops out at 280 °C or less, under the P2S's 300 °C limit, and a bed range that tops out at 100 °C or less, under its 110 °C limit. Bambu's P2S introduction says the printer sets the bed by material, and gives 100–110 °C as the ABS and PC example. The ABS spools here list 80–100 °C (Bambu) and 90–100 °C (Polymaker), so start from the spool maker's range.

Chamber heat. Bambu's P2S FAQ says the printer has no active chamber heating, but "can adjust the chamber temperature through a closed chassis and automatic switching between internal and external air circulation." The P2S introduction describes two modes. In cooling mode, used for low-temperature filaments such as PLA, a fan draws cool outside air into the chamber. In heating mode, used for high-temperature filaments, it stops drawing in outside air, and the heated bed and hotend warm the chamber while air circulates through the filter. Bambu's P2S product page calls this "50°C Chamber Ready For Engineering-Grade Filaments." Some spools below list a chamber range above 50 °C. Apart from that marketing line, Bambu's P2S spec page lists no chamber temperature.

Nozzle. Bambu's P2S FAQ says the pre-installed nozzle and extruder gear are both hardened steel, and Bambu's product page says the extrusion system and nozzle are "designed specifically for stable, long-term printing of high-performance fiber-reinforced materials." Bambu's nozzle page lists the "H2 Series/P2S Hotend" for the P2S, sold in hardened steel and stainless steel versions. If you've swapped hotends, check which one is fitted before loading a carbon-fiber spool. That hotend is rated to 350 °C, but the P2S still limits you to 300 °C.

Heat in use. Bambu's filament guide says PLA is "not recommended for environments at about 50 ℃ or higher," and lists PETG, ABS and ASA among better choices for high-temperature use. Our PLA vs PETG guide and ABS vs ASA guide cover those trade-offs.

Can you print PLA on the P2S with the door closed?

An enclosure can get too warm for low-temperature filament, which can then soften in the extruder and clog. Our PLA printing problems guide covers that kind of mid-print jam. Bambu's P2S pages and its general filament guide approach this differently.

What Bambu says for the P2S. Bambu's P2S FAQ says drawing in outside air "is more friendly to low-temperature filaments such as PLA/PETG, allowing printing without opening the cover when the ambient temperature is below 30℃." Its product page says the airflow system lets you "confidently print low-temperature filaments with the door closed." Bambu lists a 10–30 °C working temperature for the printer.

What Bambu's general filament guide says. For enclosed printers, including the P2S, Bambu's filament guide recommends opening the front door and/or removing the upper glass cover when the bed is set above 45 °C for filaments that soften below 60 °C, such as PLA and TPU. It gives the same advice for PETG when the bed is above 60 °C, though its build-plate table puts the PETG threshold at 70 °C. The guide says this matters more when the room is warm.

Bed temperature matters. Bambu's P2S introduction gives 35–45 °C for PLA on a low-temperature plate. Its filament guide lists 45–65 °C for PLA on the Textured PEI plate the P2S ships with, which can put you above the 45 °C threshold.

Our reading. In a room below 30 °C with the PLA bed at 45 °C or less, Bambu's P2S guidance supports keeping the door closed. If the room is warm, or you run the bed above those thresholds, opening the door or lifting the top glass is the cautious choice. Bambu also sells an optional external exhaust fan kit for the P2S, but its own pages don't make it a requirement for any filament here.

AMS rules to check before you buy

Bambu's P2S FAQ and AMS connection guide say the P2S supports up to four AMS 2 Pro units and four AMS HT units at once, "8 units in total with 20 slots." The first-generation AMS also works, but needs the P2S filament buffer. The P2S Combo has that buffer fitted, and the standalone P2S doesn't. Bambu's AMS guide says the AMS lite works only with A series printers, and the P2S FAQ says the AMS Hub is "Incompatible" with the P2S. These limits apply to the spools on this page:

• Spool size. Bambu's AMS 2 Pro and AMS HT spec lists both give a spool width of 50–68 mm and a diameter of 197–202 mm, the same limits its AMS notes give for the first-generation AMS. Bambu's own spools are 200 mm × 67 mm according to its technical data sheets.
• Cardboard spools. Bambu says: "We highly recommend using filament with plastic spools that fit correctly inside the AMS." For cardboard spools, it "strongly" advises a spool adapter or adapter ring "to reduce the risk of slippage and debris getting left behind in the AMS." Polymaker ships on recycled cardboard spools and says they have hardened edges that "roll great in the AMS," but it doesn't publish their dimensions. Measure before loading.
• ASA and ABS. Bambu's filament guide lists ASA as compatible with the AMS, and ABS as compatible with the AMS but not recommended for the AMS lite. Bambu's ABS store page lists the AMS 2 Pro, AMS HT and AMS as compatible.
• Fiber-reinforced filament. Bambu's AMS notes say to avoid "third-party fiber reinforcement materials (PA-CF/GF, PET-CF/GF, PLA-CF/GF, etc.)," which may wear the AMS PTFE tubes or break. Bambu exempts its own optimized PLA-CF, PETG-CF and PAHT-CF, which aren't on this page. The AMS 2 Pro spec list likewise marks "other filament that contains carbon fiber or glass fiber" as not supported, and the AMS HT routes it through a bypass filament outlet instead of its slots. Feed all four carbon-fiber spools below from an external spool or that bypass outlet.
• TPU. Bambu's filament guide marks TPU "Not Compatible" with the AMS and lists TPU 95A among filaments that are too soft. Bambu's P2S FAQ recommends printing TPU from an external spool holder. TPU for AMS is the exception. See the TPU section below.
• Drying in the AMS 2 Pro. Bambu's P2S FAQ says the printer can power the drying function of one AMS 2 Pro over the 6-pin cable when it's on standby, and print functions pause during drying. Its store page says drying while printing, or drying more than one unit, needs Bambu's separate power adapter. Bambu's AMS connection guide adds that if the printer powers drying while it prints, drying power is reduced, and it recommends the adapter. The AMS HT always needs its own power supply to dry. Bambu's filament guide gives AMS 2 Pro and AMS HT drying settings of 45 °C for 12 hours for PLA and 65 °C for 12 hours for PETG. For ABS and ASA, it marks AMS 2 Pro drying "Not recommended" and lists 80 °C for 8 hours in the AMS HT.

Bambu's P2S FAQ says the buffer's two inlets let you switch between an AMS and an external spool without unplugging the PTFE tube at the chamber inlet, as the X1 and P1 series require. For the full list, see which filaments work in Bambu's AMS.

Everyday PLA

Bambu Lab PLA Basic (Black 10101, 1 kg, with spool)

PLA Basic is Bambu's everyday PLA for its own printers. Bambu's store page marks it "All AMS Series Compatible." Its TDS (V3.0) lists a 190–230 °C nozzle, a 35–45 °C bed and a 200 mm × 67 mm spool, which is within the AMS's spool limits. The RFID tag lets the AMS read its settings automatically. This listing includes a spool. Bambu also sells refills without one.

PETG for functional parts

Bambu Lab PETG Basic (Black 30105, 1 kg, with spool)

PETG Basic is Bambu's general PETG, and its store page marks it "All AMS Series Compatible." The TDS (V3.0) lists a 230–260 °C nozzle, a 65–75 °C bed and a 35–50 °C chamber. It suits brackets, clips and fixtures that need more heat resistance than PLA. Bambu has discontinued PETG HF and points buyers to PETG Basic instead. That bed range crosses the PETG thresholds in Bambu's general filament guide, so in a warm room, open the door or lift the top glass.

Polymaker PETG (Black, 1 kg)

Polymaker's PETG product page says it "prints smoothly without requiring an enclosure and works seamlessly with AMS and multi-material systems." It lists a 240–260 °C nozzle and a 60–70 °C bed. Polymaker says PETG "is very hygroscopic," so plan on dry storage. It's on a cardboard spool, so use a spool adapter in the AMS.

TPU for flexible parts

The AMS is the main limit for TPU, not the printer. Read our TPU compatibility guide for the background on hardness and feeding.

Bambu Lab TPU for AMS (Gray 53102, 1 kg, with spool)

This is the TPU to choose if you want flexible filament in the AMS. Bambu's store page marks it "All AMS Series Compatible." At a Shore hardness of 68D, which Bambu states on the store page, it is much firmer than 95A TPU, so parts are tough rather than soft. Bambu says it "must be dried before use," and says it isn't compatible with a 0.2 mm stainless steel nozzle. The P2S's stock 0.4 mm nozzle isn't affected.

Bambu's own pages don't all agree. Its AMS notes say to avoid TPU in the AMS, and the filament guide's AMS table marks TPU "Not Compatible," without naming TPU for AMS. The AMS 2 Pro and AMS HT spec lists, though, name TPU for AMS as supported, while generic TPU and TPU 95A are not. We follow the product page and those spec lists, but check Bambu's current guidance for your AMS unit.

Bambu Lab

Bambu Lab TPU 95A HF (Black 51100, 1 kg, with spool)

TPU 95A HF is Bambu's high-speed 95A TPU, which Bambu says prints 3 times faster than its standard TPU 95A, for soft parts that need to withstand impact, collision and falling. Its store page marks it "All AMS Series NOT Compatible," so feed it from an external spool, as the P2S FAQ recommends for TPU. The store page also says it isn't compatible with the Cool Plate SuperTack, one of the plates the P2S supports, so use the stock Textured PEI plate. Keep the bed low, as described above.

• Not fed by any AMS: Bambu's store page lists all AMS series NOT compatible. Bambu's TPU and X/A2L guides allow the AMS HT only as a sealed drying chamber, fed via its TPU outlet.
• Manufacturer calls it highly sensitive to humidity and says to dry it before use and after storage.
• Bed temperature window is narrow, 30–35 °C, and the TDS calls for glue on the plate.
• Color per the listing's selected variant; check the color before buying.

ASA and ABS

The P2S is enclosed, and Bambu's filament guide recommends enclosed printers such as the P2S for these materials. All four makers below call for an enclosure. The P2S chamber warms from the bed and hotend rather than a heater, so large ABS parts are the main thing to watch. For a wider comparison, see the ASA filament shortlist.

Polymaker ASA (Black, 1 kg)

Polymaker says its ASA prints with settings very similar to ABS: "Simply use an enclosed 3D printer to ensure optimal temperature control and minimize warping." Its printing tips give a 230–260 °C nozzle and a 75–95 °C bed, and say to keep the cooling fan off and print in a well-ventilated area. Its print settings block lists 240–260 °C. Polymaker suggests drying at 70 °C for 4 hours after brief exposure, or 7 hours after extended exposure. ASA suits outdoor and sun-exposed parts. It's on a cardboard spool, so use a spool adapter in the AMS.

Bambu Lab ABS (Black 40101, 1 kg refill)

Bambu ABS is tuned for Bambu's own profiles. Its store page says "Enclosure Printers Required" and lists the AMS 2 Pro, AMS HT and AMS as compatible. It also says ABS isn't compatible with the Cool Plate SuperTack, so use the stock Textured PEI plate. The TDS (V3.0) lists a 240–270 °C nozzle, an 80–100 °C bed and a 45–60 °C chamber. The top of that chamber range is above the 50 °C Bambu advertises for the P2S. Bambu's store page warns that ABS "may release harmful gases, including styrene" at printing temperatures, and says to make sure the printer is in a well-ventilated area. This is a refill with no spool, so you need an empty Bambu reusable spool to load it.

Polymaker says to print PolyLite ABS on an enclosed printer, and lists a 245–265 °C nozzle and a 90–100 °C bed, within the P2S's 110 °C limit. Its FAQ says bigger prints need an enclosed printer (about 40–50 °C), and models bigger than about 15–20 cm in any direction "will require an actively heated chamber (~70˚C+)." The P2S has no chamber heater, so keep large ABS parts in mind. It's on a cardboard spool, so use a spool adapter in the AMS.

Can the P2S print carbon fiber without an upgrade?

This is where the P2S differs from the P1S. Its stock nozzle and extruder gear are hardened steel, so you can load these spools without changing parts. Bambu's filament guide says to always use a hardened steel nozzle for carbon- and glass-fiber filament, and never a 0.2 mm nozzle. It names a 0.6 mm hardened steel nozzle as the first choice for third-party fiber filament because it clogs less. It lists 0.4 mm, the size the P2S ships with, as the second choice, at layer heights of 0.15–0.3 mm and about 100 mm/s at most. It also says the nozzle and extruder gears need more frequent maintenance. Our worn nozzle guide covers the signs of wear.

Bambu's AMS notes and AMS 2 Pro spec list say to keep third-party fiber-reinforced filament out of the AMS, so feed all four from an external spool or the AMS HT's bypass outlet. Our abrasive filament nozzle guide and carbon fiber filament shortlist go further.

Polymaker PolyLite PLA-CF (Black, 1 kg)

Polymaker says PolyLite PLA-CF "can be printed using standard PLA settings," and that "this material is abrasive so you will need a hardened nozzle." Its specifications list "0.4mm+ hardened nozzle required," which the stock nozzle meets, with a 190–230 °C nozzle and a 25–60 °C bed. Its print settings block gives 210–230 °C and 30–70 °C, so start in the overlap. It suits stiff, matte prototypes and fixtures. It still has PLA's heat limit, so the door advice above applies.

ELEGOO PETG-CF (Carbon Fiber Black, 1 kg)

ELEGOO's specification table lists a "Hardened Steel Nozzle, ≥ 0.4 mm," a 240–270 °C nozzle, a 65–75 °C bed, a 25–50 °C chamber and enclosed printing "Not Required." Its notes say a 0.2 mm nozzle is not compatible. Drying is "Required" at 60 ± 5 °C for 8 hours in the table, though a note elsewhere on the page says 70 °C. It suits stiffer functional parts than PLA-CF. PETG-CF is on Bambu's P2S supported-filament list.

Maker's nozzle range

240–270 °C

Nozzle

Abrasive: the maker recommends a wear-resistant nozzle

Strengths

• Manufacturer states carbon fiber adds strength and rigidity, with abrasion resistance and dimensional stability.
• Manufacturer states that, compared with PLA-CF, it has superior toughness and is less prone to fracture under stress and impact.
• Manufacturer states a premium matte finish that reduces visible layer lines.

Limitations

• Abrasive: ELEGOO recommends a 0.4/0.6/0.8 mm hardened steel nozzle and says 0.2 mm nozzles are not compatible.
• Needs drying before use (60 ± 5 °C for 8 h per the spec table; the page's 'Important Notes' say 70 °C) and storage at ≤ 20% RH.
• Modest heat resistance: the spec table lists a heat deflection temperature of 74 °C at 0.45 MPa; no 1.8 MPa figure or TDS PDF is published.

Polymaker Fiberon PETG-rCF08 (Black, 0.5 kg)

Fiberon PETG-rCF08 is a PETG with recycled carbon fiber. Polymaker lists a 240–270 °C nozzle, a 60–70 °C bed, a room-temperature chamber and "0.4mm+ hardened nozzle required." Polymaker's printing tips say "An enclosed printer is recommended," though the page's specification block lists an enclosure as "Not needed." It sells this in 0.5 kg and 3 kg spools, and says carbon-fiber filament is more brittle and wound on a larger core. Dry it at 65 °C for 3 hours before use.

Maker's nozzle range

240–270 °C

Nozzle

Abrasive: the maker recommends a wear-resistant nozzle

Strengths

• Manufacturer states 8% recycled carbon fiber for added stiffness over standard PETG.
• Manufacturer states a matte finish that hides layer lines and PETG-level low warping.
• Prints at ordinary PETG temperatures (240–270 °C nozzle, 60–70 °C bed) per the TDS, with only a short 65 °C / 3 h dry.

Limitations

• Abrasive: Polymaker requires a hardened (or ruby) nozzle of 0.4 mm or larger; brass lasts about 9 h.
• Modest heat resistance: TDS heat deflection temperature is 65.7 °C at 1.8 MPa.
• Only sold in 0.5 kg and 3 kg spools, and Polymaker's enclosure guidance is inconsistent between page sections.

ELEGOO ASA-CF (Carbon Fiber Black, 1 kg)

ASA-CF combines ASA's weather resistance with carbon-fiber stiffness, and it's on Bambu's P2S supported-filament list. ELEGOO's specification table lists a "Hardened Steel Nozzle, ≥ 0.4 mm," a 250–280 °C nozzle, a 90–100 °C bed, a 45–60 °C chamber, glue on the build plate, and enclosed printing as "Required." The P2S has no chamber heater, and the top of that chamber range is above the 50 °C Bambu advertises. ELEGOO lists drying as "Required" at 80 ± 5 °C for 8 hours, while a note on the same page says 85 °C for 8 hours. It also says to print and store at 20% RH or less, sealed with desiccant. ELEGOO says ASA-CF "may produce a more noticeable odor" than standard filaments, so use a well-ventilated area.

Checklist before you buy for a P2S

• Material. PLA, PETG, TPU, ASA, ABS and carbon-fiber PLA, PETG and ASA are all on Bambu's P2S supported list.
• Temperatures. The hotend tops out at 300 °C and the bed at 110 °C. Check the spool's published ranges.
• Chamber. No active heater. Bambu advertises the P2S as "50°C Chamber Ready," with the bed and hotend warming a closed chamber. Spools that ask for a 60 °C or hotter chamber, or large ABS parts, may need extra care.
• PLA, PETG and TPU. Bambu says the door can stay closed below 30 °C room temperature. In a warmer room or with a hotter bed, open the door or lift the top glass.
• AMS. AMS 2 Pro, AMS HT and first-generation AMS (with the P2S buffer), not the AMS lite. Spools 50–68 mm wide and 197–202 mm across. Use an adapter for cardboard spools.
• TPU. Only TPU for AMS goes in the AMS. Feed softer TPU from an external spool.
• Hard particles. The stock hardened steel nozzle handles carbon fiber, but third-party fiber filament stays out of the AMS.

Drying, storage and safety

TPU and carbon-fiber filament are the most moisture-sensitive materials here. Bambu's filament guide lists drying as "Required" for TPU and PETG HF, and "Recommended" for PLA, PLA-CF, PETG, PETG-CF, ABS and ASA. Use the setting for your exact spool, and check the spool's own temperature rating before you dry it on the spool. Our filament dryer vs dry box guide and filament storage guide cover the options.

How this page was checked

This is a research-based page. We have not printed these spools on a P2S for it, so it contains no test results or scores. The printer limits come from Bambu Lab's P2S spec page, product page, store page, P2S FAQ and introduction, P2S exhaust fan kit guide, AMS connection guide, AMS 2 Pro and AMS HT store pages, nozzle page, AMS notes and filament guide. The spool statements come from each filament maker's own pages, listed in the sources section. All were retrieved on 2026-10-09. Makers update their pages, so check the current version before relying on a number. Read more in our editorial standards and affiliate disclosure.
