Bambu Lab P2S Explained: What Changed From the P1S

Bambu Lab launched the P2S on October 14, 2025 as the successor to the P1S, which has been one of Bambu’s most popular printers for years. US buyers had to wait a little longer though. Bambu held back US sales over what it called “logistics” problems, which Tom’s Hardware linked to the new tariffs on China at the time, and the P2S did not go on sale here until late November 2025. When it did, it cost $549, or $799 for the Combo with an AMS 2 Pro.

A year later, the P2S is the enclosed Bambu printer we would point most people to. On Bambu’s US store the P2S costs $549 and the Combo is now $749, so the Combo has come down $50 since launch. During Bambu’s Black Friday sale, which runs until December 1st, they are $449 and $649.

What Is the P2S?

On paper, the P2S looks a lot like the P1S. It is an enclosed CoreXY printer with the same 256 x 256 x 256 mm build volume and a 300°C max nozzle temperature. Bambu calls it “completely reengineered from the ground up,” though, and most of the new parts come straight from the H2D and H2S.

What Changed vs the P1S

• Screen: the P1S has a 2.7 inch screen with button controls. The P2S has a 5 inch touchscreen running Bambu’s second generation interface, the same style of screen the H2 series uses.
• Extruder: a PMSM servo extruder with up to 8.5 kg of extrusion force, which Bambu says is 70% more than before. It also watches for filament grinding and clogs while it prints.
• Nozzle: hardened steel out of the box, so carbon fiber and glass fiber filaments do not need a nozzle swap. The P1S spec sheet lists a stainless steel nozzle. The P2S hotend also comes out with one clip, and it takes H2D nozzles, but not A1 nozzles.
• Camera: 1080p at 30 fps, with AI detection for spaghetti, nozzle blobs, and air printing. The P1S camera is 720p at 0.5 fps.
• Flow checks: an eddy current sensor measures how the filament flows and adjusts for it automatically.
• Airflow: a flap that either pulls in cool outside air, so you can print PLA with the door closed, or keeps the heat in for ABS and ASA while a carbon filter cleans the air inside.
• Speed and bed: a 600 mm/s top speed instead of 500 mm/s, 40 mm³/s of max flow, and a 110°C bed instead of 100°C.

What the P2S does not have is an actively heated chamber. Bambu’s FAQ says it manages chamber temperature with the enclosure and that airflow flap only. If you print a lot of nylon or PC, the X2D or the H2 series are a better fit, and our post on the X1 Carbon being discontinued compares the X2D and P2S side by side.

AMS and Drying

The P2S Combo comes with an AMS 2 Pro, which can dry filament as well as feed it. In total, the P2S can connect to 4 AMS 2 Pro units and 4 AMS HT units, for up to 20 colors in one print. Be sure to read the fine print on drying though. The P2S can power the dryer on one AMS 2 Pro, but only while it is not printing. If you want to dry while printing, or dry more than one AMS 2 Pro at a time, each unit needs Bambu’s power adapter. See our guide on which Bambu AMS to buy for more.

Should P1S Owners Upgrade?

For most P1S owners, no. Bambu said at launch that the P1S will stay on sale and remain fully supported, and its FAQ says there are no plans to stop selling it. The P1S is still listed at $399 ($349 during the sale). If your P1S already prints PLA, PETG, and ABS the way you want, the P2S will mostly do the same jobs a bit faster and with fewer failed prints to catch.

The upgrade makes sense in a few cases. For example, if you print a lot of carbon fiber or glass fiber filament, the hardened steel nozzle and stronger extruder are built for it. If you leave long prints running overnight, the 1080p camera and AI detection are a big step up from the P1S camera. And if you run several printers, the touchscreen and better monitoring save a lot of small trips to the printer.

If you are buying your first enclosed printer today, get the P2S. During the sale it is only $100 more than the P1S, and that $100 gets you the hardened nozzle, the touchscreen, the better camera, and the servo extruder. If you only print PLA and PETG, the A1 at $299 ($259 on sale) is still the cheaper way in. Not sure which filaments you will use? Try our Filament Finder!

All in all, the P2S is not a brand new kind of printer, but it fixes almost everything people complained about on the P1S, from the tiny screen to the slow camera. P1S owners can keep printing happily, and new buyers should go straight to the P2S, especially while the Black Friday price lasts.
