From P1S to P2S: Closer to the Bambu Lab top models
As the successor to the popular P1S, the P2S primarily brings innovations in material handling and process reliability. For users, this means: even fewer manual settings, but more stability and more reliable print results. Of course, tinkering with the 3D printer is interesting and you learn a lot in the process. But if you just want to print reliably, Bambu Lab printers are exactly the right devices. No calibration, no trial and error, no bed leveling, etc. The print can be monitored with the camera on your smartphone. When the filament runs out, you simply reload and continue printing, etc.

The combo with 4 filaments and automatic filament change is more interesting than some might think. I see the main application here not in different colors (which I would only need sporadically), but rather in the combination of different materials in a single print. For example, you can print a special support filament that is easy to remove, or combine PETG with TPU to connect flexible parts with rigid components. Just the fact that you don’t have to load your main filaments first is a great convenience gain.
The heart of the system is the new PMSM servo motor with up to 8.5 kilograms of thrust. This makes extrusion more uniform and faster, which mainly matters for complex and detailed prints. This is complemented by automatic flow calibration, which adjusts the material flow in real time using an eddy current sensor, ensuring constant print quality.
The new 1080p camera combined with AI-based error detection can automatically recognize many common error patterns (e.g. “spaghetti”, air bubbles, clogs) and stop the print early. For the user, this means fewer failed prints and greater convenience.
With the new Quick-Swap hotend, nozzle changes are possible without tools, simplifying maintenance work. The adaptive airflow system also dynamically adjusts cooling to the filament being used - an important factor for versatile material use.
The P2S is operated via a modern 5-inch touch display with a user-friendly interface whose design has been significantly improved compared to the P1S. In combination with the AMS 2 Pro system for multi-filament printing and active filament drying, a workflow is created that comes very close to plug-and-play principles.
Bambu Lab P2S vs. P1S vs. X1C: Technology and application compared
Previously, the mid-range series (P1S) differed more technically from the upper class (X1C), which works with additional professional features such as Micro-LiDAR for quality assurance. With the P2S, this gap shrinks:
- Build volume: 256 × 256 × 256 mm for all models - a standard size that is sufficient for a wide range of applications.
- Extruder: From the stepper in the P1S, to the powerful PMSM servo in the P2S, to the high-end servo with LiDAR quality assurance in the X1C.
- Error detection: Basic camera in the P1S, 1080p AI camera in the P2S, Micro-LiDAR plus camera in the X1C.
- Operation: Keypad and basic UI UIUser Interface – the visible surface of software (windows, menus, buttons). In HA: the dashboard (Lovelace), settings and the add-on store in the P1S, 5" touchscreen with new UI generation in the P2S and X1C.
- AMS system: Classic AMS in the P1S, advanced AMS 2 Pro with active drying in the P2S and X1C.
- Speed: Up to 500 mm/s acceleration in the P2S, similarly good values in the X1C, P1S somewhat slower.
- Price: From 539 € (P1S Combo), 749 € (P2S Combo) to 999 € (X1C Combo).
Why a filament dryer makes a lot of sense
The Bambu Lab P2S Combo comes with an integrated filament drying system. Why this is a very good thing and what the science behind it is, was explained in detail some time ago by my colleague, Dr. Natalie Rudolph:
Material variety: From standard to fiber-reinforced filaments
One of the most important developments of the P2S is the expanded compatibility with abrasive and fiber-reinforced filaments. While the P1S is designed more for standard filaments such as PLA, ABS, PETG, Nylon and Polycarbonate, the robust mechanics and hardened steel nozzle of the P2S allow safe printing with carbon and glass fiber reinforced materials (e.g. PA-CF, PETG-CF).
The X1C models go one step further here and, through special nozzles and temperature management, also support high-end fiber materials that are primarily in demand in industrial prototyping and workshops.

Conclusion
The Bambu Lab P2S brings technical and functional improvements that bring it closer to the upper class in many areas. The improved extrusion, AI-supported error detection and expanded material compatibility in particular make it an interesting choice for users who want to realize high-quality prints with modern and also fiber-reinforced filaments without a lot of maintenance effort.
While the P1S has now dropped significantly in price, the P2S offers a balance between ease of use and professional features. The X1 series retains its place for users with the highest demands - but for many, the P2S is likely to be the choice with the perfect price-performance ratio.
