In the Bambu Lab P1S vs P2S comparison, the P2S is the real upgrade for people who want filament drying and easier maintenance, while the P1S remains the value pick. The P2S Combo costs $779 and the P1S Combo $549 (Amazon listings, Oct 16, 2026). They ranked #2 and #1 in Amazon Best Sellers in 3D Printers that day.
The P2S’s quick-swap nozzle was much easier to change than the P1S’s, which needs screws and unplugged connectors, according to Rad Dad’s Print Lab, a YouTube channel that logged more than 500 hours on the P2S and 1,400 on the P1S. Bambu lists up to 600 mm/s for the P2S and an AMS 2 Pro that dries filament at up to 65 °C.
Speed is not the headline. Gray Scalp Miniatures, a YouTube channel that compared the two, did not see a big real-world speed gain.

Which One Should You Buy?
The P2S Combo ($779) lists up to 600 mm/s, a PMSM servo extruder, AI failure detection, an adaptive airflow system that can hold a 50 °C chamber, and the AMS 2 Pro, which dries filament at up to 65 °C.
The P1S Combo ($549) lists 500 mm/s, an enclosed body and the original AMS. If you want filament drying and the newer features, the P2S is the upgrade. If price matters most, the P1S still ranked #1 on October 16, 2026.
My Planned Test
Planned test: if I get both printers, I plan to print the same model on each and compare setup time, print time, noise and results. I will update this post with the results and add my video when they are done.
What YouTube Reviewers Found: P1S vs P2S
Until my own hands-on test is done, here is what independent YouTube reviewers reported. These are their findings, paraphrased and linked so you can watch the full videos. Prices they mention were current when each video was made.
- In a non-sponsored comparison with 500+ hours on the P2S and 1,400+ hours on the P1S, the P2S quick-swap nozzle was much easier than the P1S, which needs screws and unplugged connectors (Rad Dad’s Print Lab, “Bambu Lab P2S or P1S? After Hundreds of Hours, Here’s My Pick”).
- The P2S camera is a big upgrade. It also has an automatic rear flap to regulate chamber air, while the P1S manual approach is to open the lid and door for PLA and PETG (Rad Dad’s Print Lab, “Bambu Lab P2S or P1S? After Hundreds of Hours, Here’s My Pick”).
- The P2S nozzle system is shared with Bambu’s newer printers, and a hardened steel extruder gear and nozzle come standard. One reviewer did not see a big real-world speed gain (Gray Scalp Miniatures, “Bambu Lab P1S Vs P2S: Which One Should You Buy?”).
- The P2S adds two internal LED bars and a full HD camera. One downside raised: it no longer filters exhaust air when printing PLA or PETG (CNC Kitchen, “The P2S Is the Upgrade No One Expected”).
