Choosing the best PETG filament for Bambu P2S owners got harder in 2026, not easier. Bambu discontinued PETG HF, the reformulated PETG Basic behaves differently, and the P2S itself is a newer machine whose profile library is still filling out. Below we rank the best PETG filament for Bambu P2S choices — this guide narrows the field to seven PETG spools that are consistently recommended by P2S owners, with the temperatures, AMS notes and trade-offs that actually decide which one belongs on your shelf.
This is a research-based guide. Every recommendation below is drawn from manufacturer specifications, published technical data sheets and documented community reports — not from hands-on testing in our own workshop. Where the community disagrees, we say so rather than smoothing it over.

| Use case | Pick | Approx. price | Why it wins |
|---|---|---|---|
| Best overall | Polymaker PETG | ~$20–24/kg | Fewest caveats of any spool here: low stringing by formulation, ±0.03 mm tolerance, Pantone-matched colours that repeat between orders. |
| Best value | Overture PETG | ~$17–19/kg | A ±0.02 mm published tolerance at a budget price. Multipacks push it under $18/kg. |
| Best without a dryer | eSUN PETG | ~$16–20/kg | Dried and vacuum-sealed before shipping, so spools tend to print clean straight from the bag. |
| Best for the AMS | Bambu PETG Basic (2026) | ~$25–30/kg | RFID auto-detection means zero profile setup for multi-colour work on the P2S. |
| Best surface finish | Polymaker Matte PETG | ~$24–28/kg | Matte scatters light and hides the ringing that glossy PETG shows at P2S speeds. |
| Best budget bulk | SUNLU PETG | ~$14–18/kg | Cheapest credible option. Expect to spend a session on retraction tuning. |
| Best high-speed | Siraya Tech PETG HF | ~$22–26/kg | A dedicated high-flow line, and the closest thing to a drop-in successor to Bambu PETG HF. |
Why the P2S is a genuinely good PETG machine
Picking the best PETG filament for Bambu P2S starts with understanding how PETG fails. PETG fails in predictable ways: it warps when the ambient temperature swings, it delaminates when the chamber is cold, and it strings when it is damp. The P2S addresses the first two by design. The enclosed chamber holds a stable ambient temperature, which is exactly what PETG wants for interlayer strength — the Bambu Lab wiki recommends an enclosed printer for PETG for precisely this reason.
| Spec | P2S | What it means for PETG |
|---|---|---|
| Chamber | Enclosed (passive) | HELPS Stable ambient temperature keeps interlayer bonding consistent on tall parts. |
| Max nozzle temp | 300 °C | AMPLE PETG lives at 230–250 °C, so there is generous headroom. |
| Build plate | Textured PEI | CAUTION PETG bonds aggressively to smooth PEI. Textured is the safe default — use glue stick as a release layer. |
| Flow sensor | Eddy-current | HELPS More accurate flow calibration than earlier Bambu models, which matters for third-party spools. |
| Third-party profiles | Partial | CAUTION Polymaker and eSUN have presets. Everything else starts from Generic PETG. |
| Stock nozzle | Stainless steel | SWAP Fine for plain PETG. PETG-CF/GF requires a hardened nozzle. |
When choosing the best PETG filament for Bambu P2S, remember the one thing the enclosure does not fix is moisture. PETG absorbs water from the air faster than PLA, and a damp spool strings no matter how well the chamber is sealed. If you buy one accessory alongside your filament, make it a dryer — our guide on how to dry filament covers the temperatures and times.
The 7 best PETG filaments for the Bambu P2S
Each of these is a strong candidate for the best PETG filament for Bambu P2S owners, sorted by the job it does best. Prices are approximate and shift with colour and sale period.
1. Polymaker PETG — the default recommendation
Polymaker reformulated its PETG in late 2025 with a high-flow compound rated to around 300 mm/s, and it has since become the most repeated answer in Bambu community threads about PETG HF replacements. Two things justify that: stringing is reduced at the formulation level rather than left to your retraction settings, and colours are matched to Pantone references, so a re-order months later still matches the part you printed in spring. Bambu Studio ships a Polymaker preset, so the P2S will not make you start from Generic. The trade-off is price — it sits above the budget brands without reaching Prusament territory.
2. Overture PETG — the value pick
Overture publishes a ±0.02 mm diameter tolerance, which is tighter than several spools costing $5 more per kilogram, and multipack pricing regularly lands under $18/kg. Layer adhesion is consistently described as excellent in community write-ups. The catch is that there is no dedicated Bambu Studio preset, so you will select Generic PETG and run the calibration sequence. On the P2S that is a short job thanks to the eddy-current flow sensor, but it is a step Polymaker buyers skip.
3. eSUN PETG — the pick if you do not own a dryer yet
eSUN dries its PETG before vacuum-sealing it, and the practical consequence is that spools arrive printable rather than pre-strung. For anyone who has not yet bought a filament dryer, that removes the single most common cause of a failed first PETG print. Tolerance is published at ±0.03 mm and the price sits in the $16–20/kg band. Colour range and surface finish are mid-pack rather than exceptional — this is a functional-parts filament, not a display-piece filament.
4. Bambu PETG Basic (2026) — the zero-setup option
The reformulated PETG Basic returned in March 2026 as Bambu’s official answer to the PETG HF discontinuation, with a compound aimed at the two loudest complaints about the original: moisture sensitivity and stringing. On a P2S with an AMS it is genuinely frictionless — the RFID tag sets the profile, and multi-colour PETG works without you touching a setting. What it is not is a drop-in speed replacement for PETG HF. Community reports consistently indicate it does not match HF above roughly 350 mm/s. If you are migrating, read our PETG HF replacement report before assuming your old profile carries over.
5. Polymaker Matte PETG — the best-looking parts
Glossy PETG is unforgiving: it shows ringing, layer lines and every flow inconsistency, and the P2S prints fast enough to generate all three. A matte compound scatters light and hides most of it. Polymaker’s matte line is the one most often singled out for surface quality in comparison round-ups. Use it for enclosures, display pieces and anything that gets photographed; use something cheaper for brackets nobody sees.
6. SUNLU PETG — the cheapest credible spool
SUNLU regularly prices at $14–18/kg, which is the floor for PETG that is worth putting in a printer. Reported diameter consistency is good. The honest caveat, repeated across several independent comparisons, is that it strings more than Overture at the same temperature and absorbs moisture faster than eSUN. Dropping to around 235 °C and increasing retraction is the usual fix. If you print PETG in volume and own a dryer, the savings are real; if you are printing your first spool, start elsewhere.
7. Siraya Tech PETG HF — for genuinely high speeds
If you bought a P2S specifically to print PETG fast, the reformulated PETG Basic will disappoint you above 350 mm/s. Siraya Tech markets a dedicated high-flow PETG line, and it is the option most often named alongside Polymaker in threads about replacing Bambu PETG HF. Budget a tuning session — high-flow compounds change how the melt zone behaves, and copying an HF profile across rarely works cleanly.
PETG print settings for the Bambu P2S
Dialing in the best PETG filament for Bambu P2S is mostly about temperature. These are starting points drawn from manufacturer data sheets and community-published profiles, not values we measured ourselves. For the best PETG filament for Bambu P2S results, run Bambu Studio’s calibration sequence after loading any third-party spool — on the P2S it takes a few minutes and it handles flow dynamics and pressure advance automatically.
| Filament | Nozzle | Bed | Speed | Fan | Dry first? |
|---|---|---|---|---|---|
| Polymaker PETG | 240–250 °C | 70–80 °C | up to 300 mm/s | 30–50% | IF OPEN >1 WEEK |
| Overture PETG | 235–245 °C | 70–80 °C | 150–250 mm/s | 30–50% | RECOMMENDED |
| eSUN PETG | 240–245 °C | 70–80 °C | 150–250 mm/s | 30–50% | USUALLY NOT |
| Bambu PETG Basic | 240–243 °C | 70–80 °C | 250–350 mm/s | RFID profile | USUALLY NOT |
| SUNLU PETG | 230–240 °C | 70–80 °C | 120–200 mm/s | 40–60% | YES |
| Siraya Tech PETG HF | 245–255 °C | 70–80 °C | 300 mm/s+ | 30–40% | RECOMMENDED |
Even the best PETG filament for Bambu P2S will string if it is wet. If your parts still string after tuning temperature and retraction, the cause is almost always moisture rather than settings. We covered the full diagnostic order in PETG stringing: causes and fixes.
Running PETG through the AMS on a P2S
Once you have chosen the best PETG filament for Bambu P2S, the AMS is the next thing to get right. PETG feeds through the AMS more reliably than TPU but demands more care than PLA. Two failure modes account for most AMS jams with PETG: a damp spool that swells slightly and binds in the PTFE path, and aggressive bed adhesion pulling the print loose during a filament swap. The first is a drying problem; the second is a plate and glue problem.
| Concern | Verdict | Fix |
|---|---|---|
| Feeding reliability | GOOD | Keep spools dry. A swollen damp spool is the #1 cause of PETG AMS binding. |
| RFID auto-profile | BAMBU ONLY | Only Bambu spools carry the tag. Third-party spools need a manual profile assignment. |
| Bed adhesion on swaps | WATCH | Glue stick as a release layer on textured PEI; prevents the part lifting during purges. |
| Multi-colour stringing | WATCH | Increase purge volume; PETG oozes more than PLA at the flush tower. |
When it comes to feeding the best PETG filament for Bambu P2S through the AMS, reliability is mostly about dryness. If you are seeing repeated jams rather than the occasional one, the problem is mechanical rather than filament-specific — our write-up on Bambu AMS jamming covers the full checklist.
Frequently asked questions
What is the best PETG filament for the Bambu P2S overall?
For most P2S owners, the best PETG filament for Bambu P2S is Polymaker PETG — the all-round choice: it strings less by formulation, holds a ±0.03 mm tolerance, has a Bambu Studio preset so you skip manual calibration, and its colours repeat between orders. If price matters more than convenience, Overture PETG delivers a tighter published tolerance for less money.
Can the Bambu P2S print PETG HF now that it is discontinued?
The best PETG filament for Bambu P2S today is not PETG HF. The P2S can still print any remaining PETG HF stock, but Bambu will not restock it once sold out. The official replacement is the reformulated PETG Basic (2026). For genuinely high-speed PETG above 350 mm/s, the community has moved to Polymaker PETG and Siraya Tech’s high-flow line rather than PETG Basic.
Do I need to dry PETG before printing on the P2S?
For the best PETG filament for Bambu P2S, drying depends on the brand and how long the spool has been open. eSUN and Bambu PETG Basic usually print clean from a fresh bag. Overture, SUNLU and any spool open longer than a week should be dried first — PETG absorbs moisture faster than PLA, and a damp spool strings regardless of your temperature settings.
What bed temperature should I use for PETG on the P2S?
Start at 70–80 °C on the textured PEI plate. PETG bonds aggressively to smooth PEI, so use the textured plate with a glue-stick release layer to protect it. The enclosed P2S chamber handles the ambient-temperature side automatically.
Does third-party PETG work in the P2S AMS?
Yes, but without the RFID auto-profile that Bambu spools get. Assign a Generic PETG profile manually, keep the spool dry to avoid feed binding, and increase purge volume for multi-colour prints since PETG oozes more than PLA.
