Best Filament for the Bambu Lab P1S and P1P (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 P1S or P1P, with or without an AMS, who want to know which spools suit the printer before buying. Both printers take 1.75 mm filament, and every spool here is 1.75 mm. For nozzles, hotends and build plates that fit, see the P1P and P1S printer page. If you own an A1 or A1 mini instead, see our A1 and A1 mini filament page.

The table is grouped by material, not ranked. The ASA and ABS spools are for the P1S only. The last three are carbon-fiber filaments, which need the hardened steel upgrade described below.

What can the P1S and P1P print, per Bambu?

Enclosure. Bambu's parameter table lists the P1P shell as "Open frame" and the P1S shell as "Enclosed (Plastic & Glass)." Bambu's P1 FAQ says the P1S adds a fully enclosed chamber, extra cooling fans and an activated carbon filter "to provide a solution for printing filaments such as ABS that are prone to emitting odors and harmful gases." The same FAQ says the P1S chamber is not actively heated: it warms up from the heated bed and "cannot be precisely controlled."

Materials. Bambu's P1P/P1S parameter table lists these supported filaments:

Bambu's filament guide is stricter about open-frame printers. It says ABS, ASA, PC, PA and their fiber-reinforced versions need "higher heatbed and chamber temperatures to suppress warping and layer separation," and lists them as "Not Recommended" on open-frame printers such as the P1P and "Recommended" on enclosed printers such as the P1S. This page recommends ASA and ABS for the P1S only. Bambu sells a P1P-to-P1S upgrade kit. Its FAQ also says the P1P reached end of life on February 10, 2026, and production and sales have ceased.

Temperatures. Bambu lists a 300 °C maximum hotend temperature and a 100 °C maximum build plate temperature for both printers. Every spool on this page has a published nozzle range that tops out at 270 °C or less, and a bed range that tops out at 100 °C or less. PolyLite ABS calls for 90–100 °C, which is at the top of what the bed can reach. Our ABS vs ASA guide explains the difference between those two materials.

PETG on the P1P. Bambu's filament guide says PETG suits open-frame printers, but adds that "an enclosed printer is recommended to prevent low ambient temperatures from reducing the model's interlayer strength." On a P1P, print PETG in a room that isn't cold. For stringing, sticking or weak layers, see our PETG printing problems guide.

PLA on the P1S. An enclosure can get too warm for low-temperature filament. Bambu's filament guide says that for filaments that soften below 60 °C, such as PLA and TPU, you should open the front door or remove the top glass cover when the bed is set above 45 °C. 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 aim is to stop filament softening in the extruder and clogging.

Nozzle. Bambu's P1P/P1S parameter table lists "0.4 mm Stainless Steel Included," and Bambu's nozzle page says the P1S ships with a 0.4 mm stainless steel nozzle. Bambu's P1S upgrade guide says the stainless hotend and extruder suit non-abrasive filaments such as PLA, PETG, ABS and TPU. Carbon-fiber, glass-fiber, metal-filled and glow filaments wear them quickly. Our worn nozzle guide covers the signs of that wear. The upgrade is covered in its own section below.

Heat in use. Bambu's filament guide says PLA is "not recommended for environments at about 50 ℃ or higher." It lists PETG, ABS and ASA as better choices for high-temperature use. Our PLA vs PETG guide covers the first trade-off.

Which spools work in the AMS on a P1S or P1P?

The P1S and P1P use Bambu's AMS. Bambu's FAQ says the P1S can connect up to four AMS units. Bambu documents these limits in its AMS notes and filament guide:

• Spool size. The AMS "supports spools with a width of 50-68 mm and a diameter of 197-202 mm." Bambu's own spools are 200 mm × 67 mm according to its technical data sheets, so they fit.
• Cardboard spools. Bambu says: "We highly recommend using filament with plastic spools that fit correctly inside the AMS." If you use 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 cardboard spools and says they have hardened edges that "roll great in the AMS," but it doesn't publish their dimensions. Measure before loading.
• TPU. Bambu's AMS notes say to avoid TPU and other flexible materials, "as they may get stuck inside the AMS feed tube." The filament guide lists TPU 95A among filaments that are too soft. Bambu sells TPU for AMS as an exception. See the TPU section below.
• 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.
• 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 and PETG-CF, which aren't on this page.

Anything that doesn't qualify can still be printed from an external spool. Bambu's P1 loading guide feeds it through the PTFE tube on the back of the printer. For the full list, see which filaments work in Bambu's AMS and AMS lite.

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.

Polymaker PolyLite PLA (Black, 1 kg)

PolyLite PLA is the cardboard-spool alternative to PLA Basic for either printer, with the AMS adapter caveat below. Polymaker's product page lists a 190–230 °C nozzle and a 25–60 °C bed. Polymaker answers "Is this material AMS compatible?" with "Yes! All Polymaker spools now have hardened edges that roll great in the AMS." Bambu still recommends an adapter for cardboard spools in the AMS, so plan on one or use the external spool.

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 and a 65–75 °C bed. 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. On a P1S, follow Bambu's advice above about opening the door or removing the top glass at these bed temperatures.

TPU for flexible parts

Bambu says the P1 series' direct-drive extruder gives "better control on the extrusion and retraction of flexible filaments." The AMS is the problem, 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 lists "Seamless AMS & AMS lite Integration" and "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 to dry it before use, and says it isn't compatible with a 0.2 mm nozzle. The 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. We follow the product's own page, but check Bambu's current guidance for your AMS unit.

Bambu Lab

• Manufacturer states its RFID tag carries the print settings, which the AMS reads.

Limitations

• At 68D it is much stiffer than typical 95A TPU, so parts are tough rather than soft and squishy.
• Manufacturer says it must be dried before use and kept moisture-free during printing to prevent stringing.
• Not compatible with a 0.2 mm stainless steel nozzle, per Bambu Lab's store page.

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 as an external spool through the back of the printer. On a P1S, keep the bed at or below 45 °C, or open the door, as noted above.

ASA and ABS (P1S only)

These materials need the P1S enclosure. Bambu's filament guide marks them "Not Recommended" on open-frame printers such as the P1P. All three makers below say to print them enclosed. 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 product page lists a 230–260 °C nozzle, a 75–95 °C bed and a 70 °C, 7-hour drying setting, and says to keep the cooling fan off and print in a well-ventilated area. ASA suits outdoor and sun-exposed parts. It's on a cardboard spool, so use a spool adapter in the AMS.

Polymaker PolyLite ABS (Black, 1 kg)

Polymaker says to print PolyLite ABS on an enclosed printer, and lists a 245–265 °C nozzle and a 90–100 °C bed. That bed range sits at the P1S's 100 °C limit. Polymaker's 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 P1S chamber isn't actively heated, so keep large ABS parts in mind.

• Manufacturer publishes a full TDS with mechanical, thermal, and drying data.

Limitations

• TDS lists a closed chamber as 'Needed'. Polymaker's product page says a non-enclosed printer with a 90 °C bed and 260 °C nozzle can handle models smaller than fist size, larger prints need an enclosed printer (about 40–50 °C), and models over about 15–20 cm need a heated chamber (about 70 °C or more).

What do the P1S and P1P need before carbon fiber?

Bambu's P1 FAQ says that to print carbon-fiber filament on a P1P or P1S, you should "upgrade it to a hardened hotend with Nozzle and Hardened Steel Extruder Gear Assembly." Bambu's filament guide says not to use a stainless steel or brass nozzle for these materials, because "their hardness is insufficient." Don't load any of the three carbon-fiber spools below until both parts are fitted.

Which hotend to buy: Bambu's P1 series version

Buy Bambu's hardened steel hotend made for the P1 series. Bambu's nozzle compatibility table lists the "P1 Series Hotend" for the P1P and P1S, and the "X1C Hotend" as a separate part for the X1C only. Its P1 FAQ links P1P and P1S owners to the P1 series hotend, and its P1S upgrade guide says to choose the P1 series version of the complete hotend. Check that a listing names the P1P or P1S before you order.

Bambu sells the P1 series hotend in two forms. The hotend on its own reuses your heater, thermistor and fan, which Bambu's replacement guide has you move over from the old hotend. The complete hotend comes with those parts already fitted. Bambu's store lists a 320 °C maximum printing temperature for the hotend, but the P1S and P1P still limit you to 300 °C.

Bambu recommends a 0.6 mm hardened steel nozzle as the first choice for third-party carbon- and glass-fiber filament, because it clogs less. It lists 0.4 mm as the second choice, at layer heights of 0.15–0.3 mm and about 100 mm/s at most. The extruder gears are a separate Bambu part. For nozzle and hotend options by printer, see our replacement nozzle shortlist.

Skip the upgrade if you only print unfilled PLA, PETG, TPU, ASA or ABS. The stock stainless nozzle is fine for those.

Carbon-fiber filament (after the upgrade)

Bambu's filament guide lists PLA-CF and PETG-CF as suitable for open-frame or enclosed printers, so these three work on either printer once it's upgraded. Bambu's AMS notes say to keep third-party fiber-reinforced filament out of the AMS, so feed all three as external spools. 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 a 190–230 °C nozzle and a 25–60 °C bed, with no enclosure needed. It suits stiff, matte prototypes and fixtures. It still has PLA's heat limit, and on a P1S the same door-open advice for beds above 45 °C applies.

Polymaker Fiberon PETG-rCF08 (Black, 0.5 kg)

Fiberon PETG-rCF08 is a PETG with recycled carbon fiber, for stiffer functional parts than PLA-CF. Polymaker lists a 240–270 °C nozzle, a 60–70 °C bed and "0.4mm+ hardened nozzle required." It says brass nozzle life may be about 9 hours. Polymaker recommends an enclosed printer, and on an open-frame printer such as the P1P, says to use its own presets. It sells this only in 0.5 kg and 3 kg spools, because carbon-fiber filament is more brittle and needs a larger spool 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.

Checklist before you buy for a P1S or P1P

• Material. PLA, PETG and TPU on either printer. ASA and ABS on the P1S only.
• Temperatures. The hotend tops out at 300 °C and the bed at 100 °C. Check the spool's published ranges.
• Spool for the AMS. Width 50–68 mm and diameter 197–202 mm. Bambu's own spools are 200 × 67 mm. Use an adapter for cardboard spools.
• TPU. Only TPU for AMS is sold for the AMS. Feed softer TPU as an external spool.
• Hard particles. Carbon-fiber, glass-fiber, metal-filled or glow filament needs a hardened steel hotend and extruder gears first, and third-party fiber filament stays out of the AMS.
• Enclosure heat. On a P1S, open the door or remove the top glass for PLA and TPU when the bed is above 45 °C.

Drying, storage and safety

PETG, TPU and carbon-fiber filament are the most moisture-sensitive materials here. Bambu's filament guide lists TPU drying as "Required" and PLA, PETG, ABS and ASA drying as "Recommended." 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 P1S or P1P for it, so it contains no test results or scores. The printer limits come from Bambu Lab's P1P/P1S parameter table, P1 series page and FAQ, P1 loading and upgrade guides, nozzle and hotend pages, AMS notes and filament guide. The spool and AMS statements come from each filament maker's own pages, listed in the sources section. All were retrieved on 2026-10-07. Makers update their pages, so check the current version before relying on a number. Read more in our editorial standards and affiliate disclosure.
