P2S
Best value enclosedThe P1S successor Bambu didn't have to make better, but did. Same build volume and a fully enclosed, passive (not actively heated) chamber, now with 600 mm/s, at $549 in Bambu's US store. The default answer to "I want a Bambu that prints ABS" alongside the P1S ($369, the budget route).

Should I buy the P2S?
Yes. It's the most straightforward buying decision in Bambu's lineup. If you want a fully enclosed machine that handles ABS and ASA reliably, costs under $600, and works out of the box, this is it. Better than the P1S, but $180 more ($549 vs $369), so the P1S stays the budget pick.
Who should buy the P2S?
- ABS, ASA and CF compositesGood fit
Bambu lists ABS, ASA, PC and carbon-filled nylons such as PA6-CF and PPA-CF for the P2S, printed through the stock hardened steel nozzle. P1S vs P2S → (Bambu P2S FAQ) - MulticolorGood fit
Up to four AMS 2 Pro plus four AMS HT units, 20 slots in total. P2S vs X2D → (Bambu wiki) - PPS and 350°C materialsLook elsewhere
The hotend tops out at 300°C and the chamber is not actively heated; the H2S adds a 350°C hotend and a 65°C heated chamber. P2S vs H2S → (Bambu P2S FAQ) - Upgrading from the P1SDepends
Faster (600 mm/s vs 500 mm/s) with a hardened steel nozzle and the same 256 × 256 × 256 mm build volume; Bambu says a P1S cannot be converted into a P2S. P1S vs P2S → (Bambu P2S FAQ)
Known issues
- Firmware 01.03.00.00 adds E3D High-Flow hotend support and 1000 mm/s travel moves, but both need Bambu Studio 2.8.3.66 or later, which is a public beta as of October 2, 2026. (Bambu release notes · Bambu Studio releases)
- No Ethernet port: Bambu's FAQ says the P2S does not support a wired network connection. (Bambu P2S FAQ)
- No active chamber heating: Bambu regulates the chamber through the closed chassis and by switching between internal and external air circulation. (Bambu P2S FAQ)

The P2S is a better P1S, but not a cheaper one: at $549 it costs $180 more than the P1S ($369 in the Bambu US store, checked October 6, 2026), which keeps the P1S as the budget pick. The 600 mm/s top speed is a genuine improvement, you'll print at 300–400 mm/s for good quality results, but the headroom is there. Like the P1S, the chamber is enclosed but not actively heated.
The P2S takes up to four AMS 2 Pro plus four AMS HT units at once (20 slots), against four units on the P1S. Bambu's own filament list for the P2S includes PC and carbon-filled nylons (PA6-CF, PAHT-CF, PPA-CF), printed through the stock hardened steel nozzle. For PPS, or a 350°C hotend with active chamber heating, you need the H2S. For PLA, PETG, ABS, ASA, and CF composites, the P2S covers everything needed.
Pros
- Best price-to-capability in Bambu's enclosed lineup
- 600 mm/s, meaningfully faster than P1S
- Passive ~50°C chamber: reliable ABS/ASA
- activated carbon filtration included
- Up to 8 AMS units (4 AMS 2 Pro + 4 AMS HT, 20 slots)
- Camera included for remote monitoring
- 110°C bed: handles engineering materials
- Full auto-calibration suite
Cons
- 300°C hotend: no PPS (the H-series goes to 350°C)
- Passive chamber only (vs active 65°C in H2S)
- Same 256mm volume as cheaper A1
- No Lidar first-layer scanning
- AMS 2 Pro sold separately ($299 in the Bambu US store)
- Cloud-dependent by default (LAN+Dev mode workaround)
| Material | Support | Notes |
|---|---|---|
| PLA / PLA+ | Excellent | Native. Open the door for better cooling if needed. |
| PETG | Excellent | Very good. Use glue on PEI to prevent over-adhesion. |
| ABS | Excellent | The ~50°C passive chamber handles ABS reliably. Let it pre-heat. |
| ASA | Excellent | Even better than ABS in some cases. Great results. |
| TPU (85A–95A) | Supported | Works well with direct drive. |
| PLA-CF / PETG-CF | Supported | On Bambu's P2S filament list. The stock nozzle is hardened steel, no swap needed. |
| ABS-GF / ASA-CF | Supported | On Bambu's P2S filament list. Stock hardened nozzle + enclosure. |
| PA / PA6-GF | Supported | On Bambu's P2S filament list. Dry filament required; without active chamber heating, large parts warp more easily. |
| PC | Supported | On Bambu's P2S filament list. No active chamber heating; the H2S's heated chamber reduces warping on large PC parts. |
| PA-CF / PPA-CF | Supported | Bambu lists PA6-CF, PAHT-CF and PPA-CF for the P2S. Dry filament required. |
ABS/ASA pre-heat: Heat the bed to 100°C and let the sealed chamber warm up for 15 minutes before starting. The ~50°C passive chamber dramatically reduces corner lifting.
PLA cooling: For PLA, crack open the door slightly or lower chamber temperature settings. The enclosure can cause over-heating for low-temp materials.
Which AMS: The original AMS (from P1S/X1C) also works with the P2S via the P2S filament buffer. If buying new, the AMS 2 Pro adds drying.
LAN mode: Enable LAN Only + Developer Mode in Settings for Orca Slicer.
P2S or P1S? P2S if you want the newest enclosed Bambu: it is faster (600 vs 500 mm/s) and better in every spec that differs. But the P1S costs $369, $180 less than the P2S ($549), which makes the P1S the budget pick and the P2S the performance pick.
P2S or A1? A1 ($299) if you only print PLA/PETG and want to spend less. P2S ($549) if you want ABS/ASA capability, an enclosure with carbon filtering, or 600 mm/s speed.
P2S or H2S? P2S covers PLA through ABS/ASA and, on Bambu's own filament list, PC and carbon-filled nylons (PA6-CF, PAHT-CF, PPA-CF) as well. H2S ($1,199) if you want a 350°C hotend and an active 65°C chamber for the most demanding grades (among current models, only the H-series lists PPS).
Does the original AMS work with the P2S? Yes. Bambu sells the original AMS with a P2S configuration; a standalone P2S needs the P2S filament buffer (included in the Combo). The AMS 2 Pro adds filament drying.

Starter accessories for the P2S
What we would add to a new P2S in the first month.
Textured 257 mm PEI plate that fits the P2S. Keep a spare so a cooling plate never blocks the print queue.
Amazon →
Capricorn XS, 1.9 mm ID. Bambu specifies 2.5 mm ID tubes for the P2S (2.0 mm inside the AMS units) and advises against a smaller ID because it adds friction. In our own printers it has still worked better than the stock tube, which is why we keep recommending it; if feeding gets worse, go back to the stock size.

Dry spools make the biggest quality jump on PETG and nylon, both of which the P2S handles well.
Amazon →
Cheap, consistent PETG for functional parts. Pairs well with the P2S enclosure and stock profiles.
