The two printers
Our pick
Bambu Lab P2S
The P1S successor: touchscreen, stronger extruder, AMS 2 Pro.
Best for Most people buying an enclosed printer in 2026

Why it stands out
- Touchscreen and USB replace the P1S's D-pad and microSD
- Extruder force roughly 70% higher than P1S (per Tom's Hardware)
- AMS 2 Pro in the Combo adds filament drying
Trade-offs
- No actively heated chamber
- TPU cannot run through the AMS
- Same 256 mm cube as the P1S

What didn't change
Same 256 mm cube, same 300 °C nozzle limit, and neither has an actively heated chamber. If you need one, look at the H2D or K2 Plus.
Frequently asked questions
Is the P2S worth it over the P1S?
At similar prices, yes: the P2S adds a 5-inch touchscreen, USB, a 1080p camera, a stronger extruder (around 70% more push force per Tom's Hardware) and power for an AMS 2 Pro. A heavily discounted P1S remains a capable printer if you are fine with its simpler interface.
Is the P2S faster than the P1S?
Both quote 20,000 mm/s² acceleration. Bambu's launch materials quote up to 600 mm/s for the P2S versus 500 mm/s for the P1S, though some retailer spec sheets list the P2S at 500 mm/s. Real print times depend more on profiles and materials than on the top speed figure.
Can the P1S use the AMS 2 Pro?
Yes. The AMS 2 Pro works with the P1S, but drying needs its own power adapter, whereas one AMS 2 Pro can be powered by the P2S itself.
