Bambu Lab P1S Review (2026)
In-depth review of the Bambu Lab P1S: enclosed CoreXY speed, filtration, and full AMS multi-color support.
Bambu Lab P1S
Enclosed speed for serious makers.
Our verdict
The P1S is the serious maker's choice: enclosed, filtered, fast, and fully multi-color capable. It costs more than the A1 and lacks a touchscreen, but for engineering filaments and long print sessions it is the better machine. Buy it if you print ABS or ASA, or want the full AMS experience.
What we like
- Enclosed chamber handles ABS and ASA well
- Same 500 mm/s performance as the flagship line
- Full AMS support for up to 16 colors
What to watch out for
- No touchscreen, controlled via app or dial
- Louder than open-frame printers
- Heavier and less portable
Who it is for
Experienced hobbyists, small businesses, and makers printing functional parts in engineering filaments.
Design and build
The P1S is a fully enclosed CoreXY machine with an activated carbon filter and an all-round cooling fan. The enclosure keeps chamber temperatures stable for warp-prone filaments and contains fumes and noise. Control is via a dial and small screen plus the excellent app and desktop software.
Print quality and speed
Performance matches the flagship X1 line closely at up to 500 mm/s. The enclosure visibly improves ABS and ASA results versus open printers. Full AMS support enables up to 16 colors with automatic filament switching, a genuine production capability for small runs.
Value
The P1S is a premium purchase, but it replaces what used to require heavy modification: enclosure, filtration, and multi-color. For makers who print daily, the reliability pays for itself in failed-print savings.

Questions, answered
P1S vs X1 Carbon: what is the difference?
The X1 Carbon adds lidar calibration, a touchscreen, and hardened components. For most users the P1S prints nearly as well for meaningfully less money.
Do I need the AMS?
Only for multi-color or multi-material printing. The P1S is excellent as a single-color workhorse; add the AMS when color becomes a real need.
How effective is the carbon filter?
It reduces odors and particulates from filaments like ABS, but it is not a substitute for ventilation. Print high-emission filaments in a ventilated space.
