Summary of "FINALLY! The Complete Bambu P2S Review"

Quick verdict

A solid, well‑finished, no‑surprises workhorse: reliable, easy to use, and capable of printing a wide range of materials well. Not cutting‑edge or flashy, but good value and a sensible choice if you want a finished consumer printer that just works. Recommended for anyone who wants a dependable machine rather than an experimental/high‑tweak system.

Main features

Positioning: mid‑range in Bambu’s lineup — sits between the feature‑rich H series and the budget A series.
Build volume: 256 × 256 × 256 mm (256 mm cube).
Bed: removable spring‑steel PEI plate (easy to swap/replace).
Tool head: quick‑swap nozzle (compatible with H2 nozzles and third‑party nozzles such as E3D). No accessory mounting for H‑series tools (drag cutter, pen plotter, laser).
Z motion: three lead screws on three guide rods for stability (rear lead screw can be tricky to access for maintenance).
AMS support: combo available with AMS2 Pro inside (supports up to four AMS or AMS HT units; up to 20 material slots in mixed setups). AMS2 Pro includes filament heating/drying and vents.
Cooling/filtration:
- Dual airflow modes: “cool” mode pulls fresh air across the part (PLA/PETG); “hot” mode recirculates through a carbon filter for high‑temp materials (ABS/ASA/PC).
- Bambu released an optional external exhaust fan kit and updated rear panel/firmware to allow external venting.
Connectivity/UI:
- Wi‑Fi, touchscreen UI (similar to H2).
- USB stick port behind the screen (replaces SD card).
- Desktop and phone apps (live monitoring, MakerWorld integration).
- Time‑lapse camera inside (1080p export, live view).
Extras: internal light, nozzle wiper, waste chute, belt tensioners.

Print performance and materials

PLA: solid, predictable baseline prints.
PETG: good with default profiles.
ABS & ASA: excellent results — good bridging, low stringing, decent surface finish.
Polycarbonate: possible but prone to bed‑adhesion/warping at the corners; mixed results.
Nylon: prints successfully when using a brim and dried filament (AMS heat); initially failed without a brim.
Chamber heating: passive/radiant from the bed — in a typical indoor room (21–23°C, ~30% humidity) the P2S reached roughly 50°C chamber temperature; results vary with ambient conditions.
Multi‑color printing via AMS works but can be long and wasteful (example: a 19‑hour multi‑colour dragon with material waste).

User experience and workflow

Very finished consumer experience: polished UI, cohesive ecosystem, and ongoing updates from Bambu.
USB drive is required for sending multiple files at once and for saving timelapses (timelapse videos are not stored to internal memory). Use low‑profile USB drives because the port sits behind the screen.
Camera provides decent monitoring but sees outside the build chamber (privacy concerns); a printable cover is included.
Closed‑door printing reduces noise, although the machine is mechanically still on the louder side.
Bambu Studio (slicer) favors usability with one‑click options (e.g., colour changes). Orca Slicer supports the machine but requires an extra app to send prints.

Pros

Reliable, predictable printing across many materials.
Strong ABS/ASA performance; PETG and PLA work well with default profiles.
Thoughtful airflow design and responsive post‑release support (external exhaust kit and firmware updates).
Strong ecosystem: AMS drying, cross‑compatible nozzles, app and MakerWorld integrations.
Well supported after release (firmware and hardware updates).
Finished consumer product: less fiddly than many competing machines.

Cons, issues, and design oddities

“Boring” design — dark gray and intentionally restrained.
No Ethernet port (Wi‑Fi only); reviewer would have preferred Ethernet for farms.
USB port position (behind screen) requires low‑profile drives to avoid damage.
Filament buffer (2:1 port) seems redundant if you use an AMS; unclear utility.
Filament reel mount placement can cause the PTFE tube to rub on the spool edge — potential wear.
In cool printing mode the carbon filter can be bypassed (air is pulled in and vented out) — some users worry about emissions for PLA/PETG (Bambu added an exhaust option).
Tool head lacks mounting for H‑series accessories (missed opportunity).
No easy access to extruder gears for clearing clogs — reviewer experienced a clog (old silk PLA) and required partial disassembly.
Rear lead screw access is awkward for maintenance.
No dedicated 4‑pin Cyber Kit port (limits some accessory connections).
Multi‑color AMS prints can be long and wasteful.
Polycarbonate and nylon require care (brims, drying, controlled environment) — not a magic solution.

Comparisons

Within Bambu lineup: less feature‑rich than the H series; more capable and more finished than the A series.
Competitors: in value/performance the P2S can outperform older fan favorites like the X1 Carbon for many users.
Build volume nuance: 256 mm vs some competitors advertising 260 mm — a small numeric difference but relevant to spec‑minded buyers.

Reviewer’s experience and anecdotes

Reviewer kept the unit for months to test many materials and scenarios.
Experienced one clog from old silk PLA and needed partial disassembly to clear it.
Printed a variety of items: a customizable travel pouch (MakerWorld), a multi‑colour dragon (19 hours), a prop helmet in PLA, and multiple ABS/ASA parts.
Recommends using brims for nylon and using AMS drying for moisture‑sensitive filaments.
Praises Bambu for listening to user concerns and releasing an exhaust kit rather than issuing a new model.

All unique points mentioned (concise list)

Mid‑range positioning between H and A series.
“Boring” but intentionally simple and clear product fit.
Unboxing: QR setup guide; shipping securing guards on lead screws and bed.
2:1 buffer port on back (questionable utility with AMS).
Filament mount placement causing PTFE rubbing.
Screen sticks out and can be tilted up but not down.
No Ethernet port (Wi‑Fi only).
USB replaces SD card; low‑profile drives advised; required for multiple files/timelapses.
Vent holes inside grab handles; auxiliary fan pulls fresh air from these vents.
Dual airflow modes: cool mode (fresh air to part, filter bypassed) and hot mode (recirculation through carbon filter).
Bambu released external exhaust fan kit and updated panel/firmware for external venting.
Tool head: quick‑swap nozzle; nozzle not centered; lacks accessory mounting.
Heated/drying AMS2 Pro included in combo; reviewer prefers AMS HT single‑reel variant for some workflows.
Can support up to 4 AMS or AMS HT combos; up to 20 slots possible.
Time‑lapse camera: 1080p export, live feed; privacy considerations.
Z axis: three lead screws; rear screw hard to access.
Build plate: compatible with existing third‑party plates.
Chamber passive heating reaches ~50°C in a typical room.
Print results: PLA/PETG good; ABS/ASA excellent; PC/nylon need special care/brims.
Software/UI: Bambu ecosystem (Bambu Studio, phone app, MakerWorld); simpler UX vs Orca Slicer.
Reviewer prefers finished products and praises Bambu’s post‑release support.

Bottom line recommendation

If you want a reliable, polished, well‑supported desktop FFF printer that handles PLA, PETG, ABS, ASA and can do higher‑temperature materials with care, the Bambu Lab P2S is a strong choice. If you want experimental add‑ons, bespoke accessory mounting (drag cutter/laser), or the absolute maximum features and build size, consider the H series or other specialized machines.
