Bambu Lab P2S 3D Printer Review

Bambu Lab's P-series has been the default recommendation for anyone who wants an enclosed printer that just works, and the P2S is the company's attempt to defend that position without cannibalising the pricier H2 line. It arrived in October 2025 at $549 standalone, or $799 for the Combo with the four-slot AMS 2 Pro, and it looks and feels like a P1S that has been quietly modernised rather than reinvented: same 256 mm cube of build volume, same fully enclosed CoreXY frame, but with a 5-inch colour touchscreen borrowed from the flagship, a new DynaSense servo extruder and an adaptive cold-air intake system.

That positioning makes the target audience fairly clear. This is for the hobbyist or small shop that prints a lot of PLA and PETG, wants the option of ABS, ASA or the occasional carbon-filled nylon, and values multi-colour capability and remote monitoring over raw industrial capability. If you're upgrading from an open-frame A-series machine or an older enclosed printer, it's an obvious step up. If you're coming from a P1S, the calculus is less clear-cut — the changes are real but evolutionary.

The extruder is the headline and it deserves to be. Going from the P1S's drive to a servo-driven unit with 8.5 kg of extrusion force — roughly 70% more — is exactly the kind of unglamorous engineering that reduces clogs and makes high-flow filaments behave. Paired with a 40 mm³/s flow ceiling, 600 mm/s toolhead speed and 20,000 mm/s² acceleration, this should be a genuinely fast machine in practice rather than just on a spec sheet. The adaptive airflow system is the other quietly clever addition: being able to leave the door shut for PLA removes the single most annoying ritual of owning an enclosed printer.

The compromises are where Bambu Lab's product laddering shows. The chamber is enclosed but only passively heated, which caps the machine's ambitions with warp-prone engineering polymers no matter what the 300 °C nozzle and 110 °C bed suggest is possible. There's no LiDAR here either, despite some launch coverage claiming otherwise — automatic bed levelling and eddy-current flow calibration cover most of that ground, but first-layer scanning stays an H2 privilege. The AMS 2 Pro's drying function is welcome and reportedly 30% quicker than sealed heating, yet it can't dry while a print runs, which blunts its usefulness on long jobs. And the switch to H2-compatible nozzles means A1 owners with a drawer of spares get nothing for free.

Ecosystem-wise, the usual caveats apply: Bambu Studio and Handy are free and polished, a LAN-only mode is there for those who want it, and the 1080p camera with a 2 TOPS NPU for spaghetti detection is a real convenience rather than a gimmick. Note that pricing appears to have drifted since launch — one owner report has the Combo at $749 — so shop around.

Rated 4.5. The P2S doesn't break new ground, but it sharpens an already excellent formula at a price that makes the alternatives look awkward. Only the passive chamber and the absent LiDAR keep it from a clean sweep, and both are deliberate choices to protect the H2 above it. One caveat on our confidence: this assessment rests on verified specs and launch claims rather than extended hands-on testing, so long-term reliability and real-world print quality remain to be confirmed.
