Bambu Lab Filament Guide: 13 Materials Compared by Use, Printer Fit and Drying

Start with PLA Basic for everyday prints, move to PETG-HF when a part needs more heat and toughness than PLA, and reach for ASA, PC or a fiber-filled nylon or PET only when the part really demands it. Those materials need an enclosed printer, a hardened steel nozzle (for the filled ones) and a properly dried spool. This guide covers the 13 core Bambu Lab materials we carry, and what each one asks of your printer.

Which printers can run which materials

Printer design decides more than material preference does.

• Open-frame printers (A1, A1 Mini, P1P, A2L): stay with PLA, PETG, TPU and PLA/PETG supports. ABS and ASA warp without a warm, stable chamber. Bambu positions the A2L specifically for low-temperature materials: it lists PLA, PETG, TPU and PLA/PETG supports, caps the heatbed at 80 °C, and says PLA-CF and PETG-CF work once you install a hardened steel nozzle.
• Enclosed printers (P1S, X1C, X1E, P2S, X2D, H2 Series): can run ABS, ASA and PC. Fiber-filled and engineering materials also need a hardened steel nozzle, and some need hotter nozzle and chamber settings than every model offers. Check Bambu's filament compatibility page for your exact printer before buying PA6-GF, PET-CF or PPS-CF. For example, Bambu lists PPS-CF for the H2D and H2S.

RFID-tagged Bambu spools are recognized automatically by Bambu printers and load their profile. Standard 1.75 mm spools work on other printers too, without the auto-detect.

Material by material

PLA Basic, Matte and Silk+

PLA is the default for a reason: it prints at low temperature, needs no enclosure and no special nozzle, and Bambu's profiles are tuned for it. Its limit is heat. PLA softens at relatively low temperatures, so keep it away from hot cars, heaters and sustained load.

The three variants differ in finish. Basic is the all-round choice with the widest color range. Matte has a flat finish that hides layer lines on models and props. Silk+ is glossy and shimmery, for display pieces and gifts. All three run on the stock stainless nozzle and in the AMS. Bambu recommends drying PLA before use but does not require it.

PETG-HF

Regular PETG strings and oozes on fast printers, which forces you to slow down. PETG-HF is Bambu's high-flow PETG, formulated to run at the speeds Bambu printers are built for. It tolerates more heat and impact than PLA, resists moisture and many household chemicals, and suits brackets, enclosures, clips and outdoor-exposed parts. It is not abrasive, so a stainless nozzle is fine. Dry it before important prints: Bambu's AMS 2 Pro setting for PETG is 65 °C for 12 hours. Shop PETG-HF

ABS and ASA

ABS handles more heat than PETG and is the one common material you can smooth with acetone vapor. The cost is warping, so it needs an enclosed printer with the chamber closed. ASA has similar mechanical properties with UV stability, which makes it the right choice for parts that live in sunlight; ABS degrades outdoors. Both need more drying heat than the AMS 2 Pro can deliver: Bambu lists them as not compatible with the AMS 2 Pro, and gives 80 °C for 8 hours in the AMS HT or 75 to 85 °C in a forced-air oven. Shop ABS · ASA

PC

Polycarbonate is the toughest unfilled material in the lineup, with high impact strength and heat resistance. It asks the most of the printer: an enclosed machine, a dry spool, and careful first-layer setup. Bambu requires drying before use and lists 80 °C for 8 hours in the AMS HT. Use it when ABS or ASA is not strong enough. Shop PC

TPU for AMS

TPU is the flexible option: gaskets, grips, cases, strain reliefs, hinges. Standard TPU is hard to push through an AMS because it compresses in the feed path, which is why Bambu makes a TPU specifically formulated for the AMS. It needs no enclosure or hardened nozzle. Drying is required, and Bambu notes the AMS 2 Pro may not fully dry TPU at its 65 °C limit, so use the heatbed or an AMS HT (75 °C, 18 hours). Shop TPU for AMS

PA6-GF

Glass-fiber nylon for gears, pulleys and brackets under repeated load. Fatigue resistance and low friction are the draw. It is also the most moisture-sensitive material here. It needs a hardened steel nozzle, an enclosed printer and a thoroughly dried spool: Bambu lists the AMS HT at 85 °C for 12 hours and a forced-air oven at 75 to 85 °C for 8 to 12 hours. It is not for the AMS 2 Pro. Start with PETG-HF or PET-CF before nylon. Shop PA6-GF

PET-CF

Carbon-fiber PET: much stiffer than PETG, with a matte finish that looks like machined hardware. Use it for brackets, drone frames, jigs and parts where flex is a failure. The carbon fiber is abrasive, so install a hardened steel nozzle first. Bambu requires drying (AMS HT 80 °C for 12 hours, or a forced-air oven at 80 °C for 8 to 12 hours). An enclosure helps layer adhesion on long prints. Shop PET-CF

PPS-CF

PPS-CF is for one scenario: continuous exposure to high temperature and aggressive chemicals at the same time. It needs a hardened steel nozzle, a printer Bambu lists for it, and a spool that is completely dry. The AMS HT cannot dry it; Bambu gives a forced-air oven at 100 to 140 °C for 8 to 12 hours, and says the heatbed method is less effective. At $129 for 0.5 kg, exhaust ASA, PC and PET-CF before choosing it. Shop PPS-CF

Supports: PVA and Support for PLA/PETG

PVA dissolves in water, which is the cleanest option for internal voids and tight overhangs. It is very moisture-sensitive and jams if wet; Bambu lists the AMS HT at 85 °C for 18 hours, and says even the AMS HT may not fully dry it. Support for PLA/PETG snaps off the model instead of dissolving, which is faster and simpler for accessible overhangs. Bambu also makes a version for PA/PET. Shop PVA · Support for PLA/PETG

Drying: Bambu's official settings

Wet filament makes steam in the hot nozzle, which shows up as stringing, bubbles, rough surfaces and weak parts. These are the temperatures and times from Bambu's drying guide. The AMS 2 Pro tops out at 65 °C (and only reaches it in a room at 25 °C or warmer); the AMS HT reaches 85 °C.

Two rules from the same guide. When you dry ABS or PETG, take PLA and TPU out of the AMS first, because those temperatures exceed PLA's and TPU's softening point. And do not dry in a microwave or a kitchen oven. Bambu specifies forced-air ovens, and the open-frame A1, A1 Mini, P1P and A2L cannot dry filament on their heatbed.

Which filament should you use?

1. New to your printer: PLA Basic. Forgiving, cheap, widest color range.
2. You care about the finish: Matte for flat, Silk+ for glossy. Same settings as Basic.
3. The part gets warm, handled or wet: PETG-HF.
4. Outdoors, in sunlight: ASA on an enclosed printer. ABS only if you need acetone smoothing.
5. It must flex: TPU for AMS.
6. Stiffer than PETG: PET-CF, with a hardened steel nozzle.
7. Load, wear or fatigue: PA6-GF, once you can dry and enclose it properly.
8. More than any of those: PC, then PPS-CF as the last resort.

FAQ

Do all Bambu Lab filaments work on all Bambu Lab printers?

No. PLA, PETG and TPU work across the lineup. ABS, ASA, PC and the nylon and fiber-filled materials need an enclosed printer, and open-frame models such as the A1, A1 Mini, P1P and A2L are limited to low-temperature materials. Check Bambu's compatibility page for your exact model before buying engineering filament.

Which Bambu Lab filaments need a hardened steel nozzle?

Anything with carbon fiber, glass fiber, glow pigment or metal fill: PET-CF, PA6-GF, PPS-CF, PLA-CF, PETG-CF, PA6-CF, PAHT-CF, ASA-CF and ABS-GF. Unfilled PLA, PETG, ABS, ASA, PC and TPU run on stainless steel. See the hardened nozzle guide and the nozzle guide.

Do I need to dry Bambu Lab filament?

PLA, PETG and ABS/ASA: Bambu recommends it. TPU, PC, PVA, nylon (PA6) and PET-CF, PPS-CF: Bambu lists drying as required. Use the table above. Remember the AMS 2 Pro tops out at 65 °C, which is not enough for ABS, ASA, PC, nylon or PET-CF.

What is the difference between PLA Basic and PLA Matte?

Same base material and price, different surface. Basic has a slight sheen that shows layer lines. Matte is flat and hides them. Use Matte for models and figurines, Basic for prototypes and functional parts.

Can I use Bambu filament on a non-Bambu printer?

Yes. They are standard 1.75 mm spools. The RFID tags only work for auto-detection on Bambu printers, so enter the temperatures manually elsewhere.
