Bambu Lab P2S vs. X1 Carbon: Is the King Dead?

Introduction

The cards are being reshuffled in the world of 3D printing. Replacing the long-time “price/performance” leader P1S, the Bambu Lab P2S is not just an update, but almost a revolution. Users are now asking the question: “When the P2S is this packed with features, why should I still buy the X1 Carbon?”

In this article, we compare the P2S Combo, equipped with Bambu Lab’s latest technologies, against the legendary X1 Carbon Combo. What you see might surprise you, because the device seen as the “lower model” actually surpasses its big brother in some aspects!

1. The AMS 2 Pro Revolution: Filament Drying Feature (The P2S Difference)

The biggest winner of this comparison might already be clear. The P2S Combo comes with the new generation AMS 2 Pro.

• P2S Combo (AMS 2 Pro): This new unit doesn’t just change colors; it actively dries your filament! Thanks to its active ventilation system, it heats the filaments to purge moisture. This is a massive innovation that directly affects print quality. Additionally, color changes are 60% faster.

• X1 Carbon Combo (Standard AMS): The X1C generally continues to be sold with the standard AMS (unless otherwise stated). This unit protects against moisture (via silica gel) but cannot perform active drying.

• Critical Difference: If you live in a humid region or use moisture-sensitive materials like Nylon/PETG, the P2S Combo’s drying AMS could be a reason to buy it all on its own.

2. Screen and Interface: Now Equals

Forget that old, button-operated screen of the P1S.

• Bambu Lab P2S: It has caught up with the X1 Carbon! It now also has a 5-inch, high-resolution touchscreen. It comes with a 2nd generation interface and is as fluid as using a phone.

• Bambu Lab X1 Carbon: Still has an excellent touchscreen. However, the P2S’s disadvantage in this area has completely disappeared.

3. Extruder and Hotend Technology: P2S Takes the Lead

Interestingly, the P2S possesses newer technology than the X1 Carbon:

• P2S (DynaSense Extruder): Bambu Lab’s new servo-motor extruder. It can detect clogs and filament grinding in real-time. Also, thanks to the “Quick Swap” hotend system, changing the nozzle takes only 30 seconds and is done with a single clip.

• X1 Carbon: Uses the classic, reliable extruder system. However, to change the nozzle, you have to deal with screws and cables, which is much more troublesome compared to the P2S.

4. Calibration: Lidar vs. Eddy Current

Both devices claim a “Perfect First Layer,” but their methods are different:

• X1 Carbon (Micro Lidar): Scans before printing with a Lidar sensor. This is still a very cool and effective technology.

• P2S (Eddy Current Sensor): Instead of Lidar, it uses a high-frequency “Eddy Current” sensor at the nozzle tip. This sensor performs flow dynamics calibration very precisely. Although it doesn’t look as “futuristic” as Lidar, in terms of functionality (especially on textured plates), it can sometimes work even more stably.

5. Cooling and Material Capabilities

• P2S (Adaptive Airflow): The P2S features a new system that draws cold air directly from outside. This ends the trouble of “leaving the door open” when printing PLA in an enclosed case. It also comes out of the box with Hardened Steel nozzles and gears; meaning it’s ready to print Carbon Fiber the moment it’s unboxed!

• X1 Carbon: Still has very good cooling and insulation, and is very successful with materials like ABS/ASA thanks to its 110°C (or 120°C) bed temperature. It also comes with hardened parts.

Comparison Summary

Conclusion: Is the King Dead?

The X1 Carbon is still a device that feels “Premium” with its build quality (aluminum exterior) and Lidar technology. However, in terms of technological infrastructure, the P2S Combo is currently the more logical choice.

Why Should You Buy the P2S Combo?

• Filament Drying: The AMS 2 Pro is a game-changer on its own.

• Ease of Use: Changing the nozzle takes seconds, great for beginners or print farms.

• New Technology: Smarter extruder and better cooling system.

• Price: It offers newer features despite likely being more affordable than the X1C.

If the X1 Carbon’s “Aluminum case” or “Lidar sensor” is not an indispensable prestige/necessity for you; the Bambu Lab P2S Combo is indisputably the best 3D printer of 2025.
