Bambu Lab P1S Review: Quick Verdict
The Bambu Lab P1S is an enclosed CoreXY 3D printer with a 256 × 256 × 256 mm build volume that its Amazon listing positions as beginner-friendly.
It is a strong pick if you want a large enclosed printer with a path to multi-color printing, as long as you don’t plan to print carbon fiber filaments.
The trade-offs: multi-color printing needs the separately sold AMS, and the listing marks carbon and glass fiber reinforced filaments as not recommended.

- Fully enclosed design for advanced filaments such as ABS and ASA
- Optional multi-color printing, up to 16 colors, with the AMS
- Automatic bed leveling and a built-in chamber camera
- Access to the MakerWorld model library through Bambu Lab’s ecosystem
Cons
- The AMS is sold separately, so multi-color printing costs extra

Bambu Lab P1S Performance and Real-World Use
Speed and Motion
The listing rates the printer at 500 mm/s with 20,000 mm/s² acceleration on a CoreXY frame. Those are maximums, and real print time depends on the model, layer height, and filament. We have not tested the printer, so treat these as spec-sheet figures.
Materials and Enclosure
The enclosed body is meant to improve results with advanced filaments. The listing rates PLA, PETG, TPU, PVA, PET, ABS, and ASA as ideal and PA and PC as capable, with a 300°C maximum nozzle temperature and a stainless steel nozzle. Reinforced filaments are where it draws the line.
Setup and Software
The listing claims setup takes about 15 minutes and highlights automatic bed leveling. It also promotes the MakerWorld model library, which gives you ready-made models to print. Multi-color printing needs the AMS, which connects to the printer and is sold separately.
Who Should Buy the Bambu Lab P1S?
A great fit if you…
- Want a larger build volume in an enclosed printer
- Plan to print PLA, PETG, TPU, ABS, or ASA
- May add multi-color printing later with the AMS
- Like starting from a library of ready-made models
Look elsewhere if you…
- Want to print carbon fiber or glass fiber reinforced filaments
- Want multi-color printing without buying an extra unit
- Prefer the newest P-series model rather than the P1S
Alternatives to Consider
- Creality K1C: a smaller 220 × 220 × 250 mm build volume, but its listing says it handles carbon fiber filaments. Read our Creality K1C review or the side-by-side comparison.
- Bambu Lab P2S: the newer P-series model, launched in October 2025. Compare its current Amazon listing with the P1S before you buy.
