Bambu Lab’s P1S has been the default recommendation for enclosed CoreXY printing for two years — and the P2S is what replaces it. Same footprint, same price bracket, but a faster toolhead, a 30-second-swap hotend, and AI failure detection baked in rather than bolted on. Here’s what actually changed, and whether it’s worth choosing over a discounted P1S.
Bambu Lab P2S by the numbers
- 600 mm/s — the P2S’s rated top print speed per Bambu Lab, a jump from the P1S’s 500 mm/s ceiling and the fastest in Bambu’s non-H2D lineup.
- 256 × 256 × 256 mm — the P2S’s build volume, unchanged from the P1S and matching Bambu’s standard enclosed-printer footprint.
- 30 seconds — how fast the P2S’s quick-swap hotend changes nozzles via a single clip, compatible with hardened-steel nozzles, versus a multi-step teardown on older Bambu printers.
- $549 → $799 — the P2S price range: $549 solo, and $699 (B&H) to $799 (Dynamism) for the P2S Combo with the AMS 2 Pro, per current US retailer pricing.
- Up to 20 colors — the maximum multi-color output when the P2S is paired with the AMS 2 Pro, Bambu’s newest automatic material system with active filament drying.
P2S configurations at a glance
| Config | Price | Adds | Best for |
|---|---|---|---|
| P2S (solo) | $549 | Printer only | Single-color printing, tightest budget |
| P2S + AMS 2 Pro Combo | $699–$799 | Auto material system, active filament drying, up to 20 colors | Multi-color / multi-material printing |
| Bambu Lab P1S (for comparison) | ~$399–$549 street | Older hotend, 500 mm/s ceiling | Budget buyers who don't need the speed/hotend upgrade |
| Bambu Lab X2D (for comparison) | ~$649 | 65°C actively heated chamber | PA-CF, PC-CF, and other warp-prone composites |
The 30-second verdict
Buy the solo P2S if you want Bambu’s fastest enclosed printer under $600. The 600 mm/s speed ceiling and 30-second hotend swap are genuine upgrades over the P1S, not marketing repackaging, and the 256×256×256 mm build volume covers the vast majority of hobbyist and prototyping prints.
Add the AMS 2 Pro Combo if multi-color matters. At $699–$799 it costs more than a solo P1S, but the newest-generation AMS brings active filament drying — worth it specifically for moisture-sensitive filaments like nylon blends and some PETGs.
Buy a discounted P1S instead if price is the only factor. Street pricing on the outgoing P1S has dipped into the $399–$549 range at some retailers, and it still handles PLA, PETG, and ABS printing just as reliably — you’re trading the P2S’s speed and hotend convenience for savings.

What’s actually new versus the P1S
The P2S isn’t a cosmetic refresh. Top speed climbs to 600 mm/s from the P1S’s 500 mm/s ceiling, a 20% increase that shortens print times on larger, multi-hour jobs. The quick-swap hotend is the more practical upgrade day to day: a single-clip mechanism lets you change nozzles — say, from a 0.4mm standard to a 0.6mm hardened-steel nozzle for abrasive filament — in about 30 seconds, replacing the slower teardown process older Bambu printers required.
Bambu also redesigned the interface: a 5-inch touchscreen runs a new second-generation UI on a more powerful processor, and AI failure detection now ships natively rather than requiring a subscription add-on. An adaptive airflow cooling system with cold-air intake rounds out the hardware changes, aimed at improving overhangs and low-temperature filament (like TPU) that struggle on printers with less controllable part cooling.
AMS 2 Pro Combo: what the upgrade buys you
Pairing the P2S with the AMS 2 Pro brings Bambu’s newest automatic material system, capable of up to 20-color prints. The meaningful upgrade over older AMS units is active filament drying — the AMS 2 Pro vents and dries filament during storage and printing rather than just feeding it, which matters most for moisture-sensitive materials like nylon blends and some PETG formulations that print noticeably worse once they’ve absorbed ambient humidity.
At $699–$799 for the Combo versus $549 solo, the $150–$250 premium is worth paying specifically if multi-color or multi-material printing is a regular part of your workflow — skip it if you’re running single-color PLA and PETG almost exclusively, since the solo P2S is the identical printer without that hardware.
No heated chamber: know the material ceiling
Like the P1S before it, the P2S is passively enclosed, not actively heated — its enclosure traps ambient heat rather than driving the chamber to a controlled temperature the way the Bambu X2D or H2D do. That’s enough for PLA, PETG, ABS, and even CF-PLA or CF-PETG blends. But carbon-fiber nylon (PA-CF) and polycarbonate composites (PC-CF) warp badly as they cool without active chamber heating, so buyers set on those materials should look at the X2D’s 65°C heated chamber instead — see our best carbon fiber 3D printer guide for the full breakdown.
Bottom line
The Bambu Lab P2S is a real, hardware-level upgrade over the P1S rather than a rebrand — faster printing, a genuinely useful quick-swap hotend, and AI monitoring that used to cost extra now come standard. Buy the solo P2S ($549) if single-color printing covers your needs and speed matters. Add the AMS 2 Pro Combo ($699–$799) for multi-color work. And if budget is the only constraint, a discounted P1S still gets the job done for less — just without the P2S’s speed and convenience gains.
