Best Filament for the Bambu Lab H2D and H2S (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 H2D or H2S, with or without an AMS 2 Pro or AMS HT, 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 H2D and H2S printer page. If you own a P1S or P1P instead, see our P1S and P1P filament page.

The table is grouped by material, not ranked. The first six are everyday filaments that print with chamber heating off. The next four are engineering materials that benefit from the heated chamber. The last five are carbon-fiber filaments.

What the H2D and H2S can print, per Bambu

Hardware. Bambu's tech specs pages list the same core numbers for both printers:

The H2D is a dual-nozzle printer. Bambu's nozzle page says the two nozzles are independent, and gives the example of loading the model filament into one and support filament into the other. The H2S has a single hotend.

Materials. Bambu's H2D spec page lists these supported filaments: "PLA, PETG, TPU, PVA, BVOH, ABS, ASA, PC, PA, PET, Carbon/Glass Fiber Reinforced PLA, PETG, PA, PET, PC, ABS, ASA, PPA-CF/GF, PPS, PPS-CF/GF." The H2S page lists the same base materials and fiber-reinforced blends, worded slightly differently. Bambu's filament guide lists the "Bambu H2 Series" as an enclosed printer, "Recommended" for ABS, ASA, PC, PA and their fiber-reinforced versions.

Temperatures. Every spool on this page has a published nozzle range that tops out at 300 °C or less and a bed range that tops out at 120 °C or less. Prusament PC Blend Carbon Fiber is the closest to a limit: Prusa lists a 110 ± 10 °C bed, which reaches the 120 °C maximum.

Nozzle. Both printers ship with a hardened steel nozzle and hardened steel extruder gears, so the carbon-fiber spools here need no upgrade. Bambu's filament guide says not to use a stainless steel or brass nozzle for fiber-filled filament, because "their hardness is insufficient." Bambu's H2 series hotend is sold in hardened steel and stainless steel versions, so if you've swapped hotends, check which one is fitted before loading a carbon-fiber spool. Bambu recommends a 0.6 mm hardened steel nozzle as the first choice for third-party carbon- and glass-fiber filament, and 0.4 mm as the second. For the 0.4 mm nozzle, it suggests layer heights of 0.15–0.3 mm and about 100 mm/s at most.

Can you mix PLA and ABS on the H2D?

The heated chamber helps ABS, ASA, PC and nylon, but it can clog low-temperature filament. Bambu's H2D/H2C multi-material guide sorts filament into three groups:

• High-temperature filaments "require printing at the highest possible chamber temperature." Bambu lists ABS, ASA, ASA-CF, PC, PA, PA-CF, PA-GF, PA6-CF, PET-CF, PPS, PPS-CF, PPA-CF, PPA-GF, ABS-GF and ASA-Aero.
• Medium-temperature filaments such as HIPS, PE, PP and EVA print well without chamber heating. Bambu says to take care when printing them alongside high-temperature filaments, because they may soften and clog, and to adjust the chamber temperature carefully.
• Low-temperature filaments "may soften inside the extruder or hotend, causing clogging" once the chamber exceeds 45 °C, so "they are strictly prohibited in high-temperature chamber environments." Bambu lists PLA, PETG, PETG-CF, TPU, TPU-AMS, PLA-CF, PLA-Aero, PVA, BVOH and PCTG.
• Mixing. "High-temperature and low-temperature filaments must not be printed together," and Bambu Studio enforces this when slicing. On an H2D, that means you can't print PLA from one nozzle and ABS from the other in the same job.

For third-party filament, Bambu says to treat anything with a heat deflection temperature below 80 °C (ISO 75, 1.8 MPa) as low-temperature, or to ask the filament maker.

Door and top cover for PLA and PETG. Bambu's filament guide says that for filaments that soften below 60 °C, such as PLA and TPU, you should open the front door and/or remove the upper glass cover plate 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 and PETG-CF threshold at 70 °C. Bambu says this matters more in a warm room. The H2S intro adds that when the printer runs without chamber heating, it enters a cooling mode that opens the chamber intake vent and exhaust grille to let heat out. It also says the H2S door sensor shows a "door open" warning but keeps printing when no laser module is in use.

H2D laser editions. Bambu's H2D FAQ says that when you print low-temperature materials such as PLA or TPU after laser work, you should disconnect the exhaust pipe from the printer, or at least disconnect the air purifier. Bambu says the air purifier in particular blocks airflow significantly.

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

Which AMS units and spools work with the H2D and H2S?

Bambu's multi-model AMS guide says the H2D and H2S support up to four AMS 2 Pro and eight AMS HT units connected at once. Its H2D FAQ says the first-generation AMS also works on the H2D, without the drying function, and that the H2D does not support the AMS lite. The AMS guide says the AMS lite works only with A series printers, so it doesn't fit the H2S either. These limits apply to the spools on this page:

• Spool size. Bambu's AMS notes say 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.
• 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 cardboard spools and says they have hardened edges that "roll great in the AMS." It doesn't publish their dimensions, so measure before loading.
• ASA, ABS and PC. Bambu's filament guide lists ASA, ABS and PC as compatible with the AMS. It notes that this covers loading and unloading only.
• 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 fiber filaments, which aren't on this page. Feed all five carbon-fiber spools below from an external spool.
• TPU. Only TPU for AMS goes in the AMS. Bambu's H2 TPU guide says all other TPU "requires manual feeding." The AMS HT can hold TPU 95A HF as a spool holder, but you still feed it by hand. See the TPU section below.
• Drying in the AMS. 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, ASA, PC and nylon, it marks AMS 2 Pro drying "Not recommended" and lists AMS HT settings of 80–85 °C instead. Bambu's AMS guide says an H2 series printer can power drying for only one AMS 2 Pro, and additional units need their own power adapter.

For the full list, see which filaments work in Bambu's AMS. If a compatible spool still tangles, slips or jams, see our AMS feeding problems guide.

Everyday PLA

Print both of these with chamber heating off, and follow the door and top-cover advice above if you run the bed above 45 °C.

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 here, printed the same way with chamber heating off. 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's H2D/H2C multi-material guide classes PETG as a low-temperature filament, so print it with chamber heating off too.

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. At these bed temperatures, follow Bambu's door and top-cover advice above.

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 calls it "very hygroscopic," so plan on dry storage. It's on a cardboard spool, so use a spool adapter in the AMS.

Skip it if you can't keep filament dry, or don't want to fit a cardboard-spool adapter.

TPU for flexible parts

Bambu's H2 TPU guide covers the H2D, H2S and H2C. On the H2D, Bambu's filament printing guide says TPU "must be printed using the right hotend," because of a higher clogging risk on the left. Bambu also recommends not using a hotend that has printed carbon- or glass-fiber filament, because leftover fibers raise extrusion resistance. If you must, it says to do 3–5 cold pulls first. 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 H2 TPU guide lists TPU for AMS as compatible with the AMS, AMS 2 Pro and AMS HT, and says it "can be directly placed in the AMS series." Its 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. The H2 TPU guide recommends 0.4, 0.6 or 0.8 mm nozzles and says 0.2 mm and standard high-flow nozzles aren't supported.

Bambu Lab

• Manufacturer states it is optimized for the AMS, and its store page marks it compatible with all AMS series, including the AMS lite.
• Manufacturer states it prints up to 60% faster than Bambu TPU 95A HF and greatly reduces stringing.
• 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." Bambu's H2 TPU guide lists it as not compatible with the AMS or AMS 2 Pro, and compatible with the AMS HT only as a holder you feed by hand. In the guide's AMS HT method, it runs through a PTFE tube to the dedicated TPU inlet on the back of the printer and into the right hotend on an H2D. The guide also describes a top-feed rack. It recommends 0.4, 0.6 or 0.8 mm nozzles and says 0.2 mm and standard high-flow nozzles aren't supported.

• Manufacturer states it comes on a high-temperature reusable spool (PC + ABS, rated 90 °C).

Limitations

• 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, ABS and PC (with the chamber heated)

These are the materials the H2 chamber heater is for. Bambu's multi-material guide says they need "the highest possible chamber temperature" for layer bonding and shrinkage control. On the H2D, Bambu bars putting them in the same print as PLA, PETG or TPU. Bambu doesn't publish that rule for the H2S, but we'd avoid mixing them there too. For a wider comparison, see the ASA filament shortlist and our ABS vs ASA guide.

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.

Overture ASA (Black, 1 kg)

Overture's product page lists "Enclosed Printer Required," a 240–270 °C nozzle, a 70–95 °C bed and drying at 75 °C for 7 hours. Overture says ASA "does produce some odor during printing," and advises good ventilation and considering air filtration. Overture doesn't publish spool material or dimensions, so check the spool against the AMS limits above before loading it.

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, well within the H2's 120 °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+)." Bambu lists a 65 °C maximum chamber temperature, a little below that figure, so very large ABS parts may still need care.

• TDS lists a heat deflection temperature of 98 °C at 1.8 MPa.
• 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).
• Needs a 90–100 °C bed (TDS), so printers with low-temperature beds aren't suitable.

Polymaker PolyLite PC (Transparent, 1 kg)

PolyLite PC is a translucent polycarbonate for stiff, heat-resistant parts. Polymaker lists a 250–270 °C nozzle and a 90–105 °C bed, and its printing requirements say "Enclosed printer that can trap heat required" and "Actively heated chamber highly recommended. Minimum 60˚C chamber temp highly recommended." The H2's 65 °C chamber meets that minimum, but Polymaker's TDS (V5.4) lists a 70–100 °C chamber, above the H2's maximum, so large PC parts may still need care. Polymaker recommends annealing at 90 °C for 2 hours after printing, and a dryer or dry box. Bambu's filament guide lists PC drying as "Required" and puts the PC bed at 100–120 °C on its own plates. It's on a cardboard spool, so use a spool adapter in the AMS.

Can the H2D and H2S print carbon fiber?

The H2D and H2S ship with hardened steel nozzles and extruder gears, so these five spools need no upgrade. Bambu's AMS notes say to keep third-party fiber-reinforced filament out of the AMS, so feed all five from an external spool. The first two are low-temperature filaments in Bambu's grouping, so print them with chamber heating off. Our abrasive filament nozzle guide and carbon fiber filament shortlist go further, and our PLA-CF vs PETG-CF guide compares the first two materials below.

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 the same door-open advice for beds above 45 °C applies.

190–230 °C

Nozzle

Abrasive: the maker recommends a wear-resistant nozzle

Strengths

• Manufacturer states 8% chopped carbon fiber gives exceptional rigidity and strength.
• Manufacturer states a matte black finish with virtually invisible layer lines and low shrinkage.
• Manufacturer states it prints with standard PLA settings; the TDS lists no enclosure needed.

Limitations

• Abrasive: Polymaker strongly recommends a hardened nozzle.
• Not suited to heat: the TDS lists a heat deflection temperature of 50 °C (1.8 MPa).
• Cardboard spool: Bambu Lab strongly advises a spool adapter or adapter ring for cardboard spools in the AMS.
• The Amazon listing's bullet points describe plain PolyLite PLA, though its title and model number (PA10001) are the carbon-fiber version. Check that the title says Carbon Fiber PLA before you buy.

Skip it if the part will see heat.

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 and enclosed printing "Not Required," with a 25–50 °C chamber. 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. Bambu classes PETG-CF as low-temperature, so keep chamber heating off.

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

ASA-CF is the carbon-fiber pick that uses the heated chamber. ELEGOO's specification table lists a "Hardened Steel Nozzle, ≥ 0.4 mm," a 250–280 °C nozzle, a 90–100 °C bed, enclosed printing "Required" and a 45–60 °C chamber, which fits under the H2's 65 °C maximum. It requires build-plate glue and drying at 80 ± 5 °C for 8 hours (a page note says 85 °C). ELEGOO says to print it in a well-ventilated area because it "may produce a more noticeable odor" than standard filaments.

Prusament PC Blend Carbon Fiber (Black, 800 g)

This is a carbon-fiber polycarbonate blend for heat-stressed parts. Prusa's material page says "Hardened steel nozzle needed (abrasive material)" and "Enclosure not needed," and lists heat resistance of 114 °C, or up to 130 °C after annealing. Its TDS lists a 285 ± 10 °C nozzle and a 110 ± 10 °C bed. That bed range reaches the H2's 120 °C maximum. Prusa says no drying is needed before printing. It comes in an 800 g spool, and Prusa doesn't publish the spool dimensions.

• Manufacturer states excellent temperature resistance (114 °C), up to 130 °C with annealing.
• Manufacturer states an enclosure is not needed, with good UV stability and resistance to common chemicals.
• Manufacturer states a professional-looking matte finish and lighter weight than unmodified PC Blend.

Limitations

• Abrasive: Prusa states a hardened steel nozzle is needed.
• Needs a hotend reaching 285 ± 10 °C and a heated bed at 110 ± 10 °C per the TDS.
• Spool holds 800 g, and diameter tolerance is ±0.04 mm, looser than Prusa's unfilled filaments.
• The data sheet's 285 ± 10 °C nozzle range tops out above the 290 °C maximum Prusa lists for the MK4S, CORE One, and XL hotends; stay at or below your printer's limit.

Polymaker Fiberon PA612-CF15 (Black, 1 kg)

Fiberon PA612-CF15 is a carbon-fiber nylon for strong, stiff functional parts. Polymaker lists a 250–300 °C nozzle, "0.4mm+ hardened nozzle required," a 40–50 °C bed and drying at 100 °C for 10 hours, and says to store and print it below 20% RH. Its chamber guidance differs from Bambu's grouping. Bambu lists PA-CF among filaments that want the highest chamber temperature, but Polymaker says "an actively heated chamber is not required." Its FAQ adds that for its Warp-Free technology to work, "the build plate and the ambient air temperatures are both below 50˚C." For this spool, follow Polymaker's settings rather than Bambu's generic PA-CF profile.

Maker's nozzle range

250–300 °C

Nozzle

Abrasive: the maker recommends a wear-resistant nozzle

Strengths

• Manufacturer states significantly lower moisture sensitivity than PA6/66 and PA6-based nylons.
• TDS lists 91.9 MPa X-Y tensile strength dry and 83.1 MPa after moisture conditioning (annealed specimens).
• Manufacturer states Warp-Free technology for print size stability.

Limitations

• Abrasive: the TDS highly recommends a hardened steel or ruby nozzle (brass lasts about 9 h).
• Needs a 250–300 °C hotend; Polymaker's product page recommends an enclosure, and the TDS recommends annealing at 100 °C for 16 h for full properties.
• Still hygroscopic: the TDS says to store and print below 20% RH and dry at 100 °C for 10 h.

Skip it if you can't dry filament at 100 °C, or don't want to anneal parts. Polymaker recommends annealing at 100 °C for 16 hours to reach the published strength.

Checklist before you buy for an H2D or H2S

• Material. Bambu supports PLA, PETG, TPU, ASA, ABS, PC and nylon on both printers, plus carbon-fiber blends of all of them except TPU.
• Temperatures. The hotend tops out at 350 °C, the bed at 120 °C and the heated chamber at 65 °C. Check the spool's published ranges.
• Chamber heat. Keep chamber heating off for PLA, PETG, TPU, PLA-CF and PETG-CF, and open the door or top cover at higher bed temperatures. Don't mix those with ABS, ASA, PC or nylon in one print. Bambu Studio blocks this on the H2D.
• 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 feeds from the AMS. Feed softer TPU by hand, through the right hotend on an H2D.
• Hard particles. The stock hardened steel nozzle handles carbon fiber, but third-party fiber filament stays out of the AMS.

Drying, storage and safety

PETG, TPU, PC, nylon and carbon-fiber filament are the most moisture-sensitive materials here. Bambu's filament guide lists TPU, PC, PA and PA-CF 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 an H2D or H2S for it, so it contains no test results or scores. The printer limits come from Bambu Lab's H2D and H2S tech specs pages, H2D FAQ, H2S intro, H2D filament and multi-material guides, H2 TPU guide, nozzle page, AMS notes, multi-model AMS guide and filament guide. The spool statements come from each filament maker's own pages, listed in the sources section. All were retrieved on 2026-10-07. Makers update their pages, so check the current version before relying on a number. Read more in our editorial standards and affiliate disclosure.
