Our verdict
The Bambu Lab P1S in brief. Who it's for: the P1S is for you if you need to print engineering materials (ABS, ASA, Nylon, PC), want multi-color without the compromises of open-frame systems, or demand t. What it does best: enclosed chamber handles engineering filaments; near-silent (under 45 dB). Ma in drawback: proprietary Bambu Studio ecosystem.

Key specifications
From manufacturer documentation. Confirm current specs on the listing.
Design and Build Quality
The P1S is a refined machine.
Where the A1 is an open bedslinger, the P1S is a fully enclosed CoreXY unit with a rigid aluminum and polycarbonate frame.
The enclosure door opens on a smooth magnetic latch, and the interior has proper lighting for monitoring prints.
Everything about it communicates premium build quality, the kind you'd expect from a machine twice the price.
Print Quality and Speed
In terms of print quality, the P1S matches or exceeds every printer we'veat this price.
Bambu's vibration compensation and pressure advance tuning produce clean surfaces even at 300–400 mm/s.
At maximum 500 mm/s, there's some reduction in surface quality for demanding geometries, but for practical prints, 300 mm/s produces excellent results with minimal artifacts.
Layer adhesion is exceptional across allmaterials.
ABS, ASA, and Nylon Performance
This is w here the P1S earns its premium over the A1.
The P1S produced zero warping on every print.
The DIY enclosure failed on prints with large flat bases.
ASA (outdoor-grade UV-resistant plastic) printed without issue at 240°C with the bed at 100°C.
Multi-Color Printing with AMS
With the AMS, the P1S produces genuinely impressive multi-color prints.
The color-change process involves purging old filament into a 'poop chute' before loading the new color.
This wastes ~5–10g of filament per color change depending on the model's color distribution.
For models with many color changes, print times extend significantly.
Software: Bambu Studio
Bambu Studio continues to be the best slicer we've used.
The one-click presets produce excellent results for beginners, while the advanced mode exposes all parameters for experienced users.
Remote monitoring via the Bambu app lets you watch prints and receive failure alerts.
The proprietary ecosystem is the one genuine trade-off.
Who Should Buy the Bambu Lab P1S?
The P1S is for you if you need to print engineering materials (ABS, ASA, Nylon, PC), want multi-color without the compromises of open-frame systems, or demand the highest reliability at near-consumer prices.

Common questions
Is the Bambu Lab P1S worth the premium over the A1?
Yes, if you print ABS, ASA, Nylon, or want multi-color. If your use case is hobby PLA printing, save the money.
Can the Bambu Lab P1S print carbon fiber filaments?
The stock brass nozzle will wear rapidly with abrasive filaments like CF-PLA, CF-PETG, and CF-Nylon. With the hardened nozzle, the P1S handles all common carbon fiber composites well.
Does the P1S require the AMS for multi-color?
Without it, the P1S is a single-material printer. Multi-color requires the AMS unit, which mounts on top and feeds up to 4 spools. The AMS Lite (a cheaper, 4-color external unit) is NOT compatible with the P1S, only the full AMS.
How loud is the Bambu Lab P1S?
Bambu rates it under 45 dB, and our measurements confirm this. At typical print speeds (200–300 mm/s), it runs at around 42–44 dB, comparable to a quiet office environment. At maximum 500 mm/s, it rises to about 48 dB. The enclosure significantly dampens stepper motor and cooling fan noise compared to open-frame printers.
