With improvements in practically everything —from thermal control to material management and the extrusion system—, this 3D printer arrives with second-generation technology ready to make the competition sweat. 🚀

In this guide we tell you everything you need to know: what's new, how it compares to other top models on the market, and why it could (or could not) be your next FDM beast. We also include direct links to the official pages so you can explore more on your own. 🧐

What makes the P2S special?

The P2S is a CoreXY FDM 3D printer with a build volume of 256 × 256 × 256 mm. It is designed for demanding users who want to print both decorative and functional parts using advanced materials. Some of the improvements it brings over the P1S include:

• PMSM servo extruder with 8.5 kg of force, capable of moving filament with precision at high speeds.

• 5″ touchscreen with a smartphone-style interface, offering intuitive menus and built-in tutorials.

• Eddy current sensor to calibrate flow in real time and compensate for variations in corners and curves.

• Adaptive cooling system that allows operation with the enclosure closed at 50 °C for technical materials, or open for filaments such as PLA.

• 1080p AI camera to detect printing failures and monitor the first layer.

• Quick-swap nozzle: the entire hotend is replaced in seconds with no tools required.

• AMS 2 Pro compatibility, Bambu's multicolor feeding and drying system, which allows printing up to 20 colors/materials and drying filaments with 30% greater efficiency.

With these innovations, the P2S becomes an intermediate model between Bambu's P series and H series, inheriting many features from the X1 Carbon while maintaining a more accessible price point.

Technical specifications

To assess whether this 3D printer suits your needs, here is a summary of its specifications:

Enhanced user experience

One of the most notable changes in the P2S is the redesigned interface. The 5″ screen uses a proprietary operating system with large icons and smooth animations. The assistant guides you through levelling, calibration and maintenance processes, so even users without experience get good results from the very first print.

• Automatic levelling: the bed calibrates in seconds using integrated sensors and automatically adjusts the Z axis.

• Flow calibration: the current sensor analyses filament pressure during extrusion and immediately corrects any variation, preventing the typical bulging at corners.

• Real-time alerts: if the 3D printer detects a filament jam or an error on the first layer, it sends a notification to the user and pauses the print to avoid wasting material.

Thanks to these controls, the P2S can print at high speeds with greater reliability than many similar models.

Powerful and stable extrusion

The PMSM servo extruder is one of the cornerstones of the P2S. By delivering up to 8.5 kg of force, it can move filament with precision even at high speeds. This translates into several advantages:

• Fewer slips: rigid and loaded filaments (such as PLA‑CF or PETG‑CF) are fed without skipping, maintaining consistent extrusion.

• Greater speed: the 3D printer can reach 600 mm/s without over‑extrusion zones or voids occurring.

• Early jam detection: the motor measures resistance and detects any anomaly before it causes a serious failure.

Combined with the current sensor, the servo extruder results in superior quality on walls and complex geometries.

Adaptive air system

Another differentiating aspect is the ability to adjust ventilation according to the material. The P2S offers three modes:

1. External cold air: ideal for PLA and TPU, prevents the chamber from overheating.

2. Filtered recirculation: captures VOCs and particles, keeping the chamber closed for moderately technical filaments like PETG.

3. Chamber heated to 50 °C: essential for ABS, ASA or PC, reduces warping and cracking.

This level of temperature control and filtration is rarely found in 3D printers in the same price range. Models like the Creality K2 Plus or the Prusa Core One feature a closed chassis, but do not offer such fine air control or integrated filters.

AI failure detection

The built-in camera uses computer vision algorithms to monitor the print. Some of its functions include:

• Detecting when the part detaches from the bed and the dreaded "spaghetti" forms.

• Alerting if the nozzle becomes clogged or stops extruding correctly.

• Evaluating first layer adhesion and pausing the print if poor adhesion is detected.

This feature is not common in the market. Although the X1 Carbon from Bambu offers a similar function, 3D printers from other brands rely on the user's eye or external cameras.

Nozzle swap in seconds

The P2S simplifies maintenance with a quick-change hotend. The entire block releases with a clip and is replaced without tools. Switching from 0.4 to 0.6 mm —or to a steel nozzle for abrasive filaments— takes less than a minute.

This is very practical for those who alternate between fine and large parts or between abrasive and standard materials. On models like the Core One or the K2 Plus, changing the nozzle requires tools and manual recalibration.

Multicolor printing with AMS 2 Pro

The AMS 2 Pro system allows loading up to 20 spools (four modules of four spools each) and actively drying the filament. Its main advantages are:

• Multicolor and multi‑material printing with fast and precise changes.

• More efficient drying, essential for hygroscopic materials like nylon or PETG.

• Tangle and empty spool detection. The system pauses the print and alerts the user.

Compared to the CFS system of the K2 Plus, the AMS 2 Pro performs smaller filament purges and manages waste more efficiently. Additionally, the PMSM motor reduces swap time, saving up to 10 minutes over 100 color changes.

Comparisons with other printers

When deciding which 3D printer to buy, it is useful to see how the P2S stacks up against other popular models. Below we analyze some notable rivals.

Versus P1S

The P1S was the first Bambu 3D printer to offer a closed chassis. By comparison, the P2S adds:

• Servo extruder with 8.5 kg of force.

• 5″ interface and second-generation software.

• Adaptive air system with heated chamber.

• AI-powered failure detection.

Therefore, the P2S is ideal if you are looking for a qualitative leap in performance and ease of use.

Versus X1 Carbon

The X1 Carbon is Bambu's flagship 3D printer and shares some features with the P2S, but adds extras such as the Micro LiDAR sensor (7 μm) for millimeter-precise first layer calibration. In return, it comes at a considerably higher price. If you do not need absolute maximum precision, the P2S offers most of the X1's features at a more moderate cost.

Versus Creality K2 Plus

The K2 Plus from Creality stands out for its enormous build volume (350 × 350 × 350 mm) and its ability to print in multiple colors via the CFS system. However:

• It does not have AI for failure detection.

• The heated chamber control is less advanced and lacks a carbon filter.

• The Klipper interface can feel less intuitive for beginners.

• The color purge system generates more filament waste.

If you need a large build volume, the K2 Plus is a valid option; but for a standard volume with a more refined workflow and more consistent results, the P2S is superior.

Versus Prusa Core One

The Core One is Prusa's take on enclosed CoreXY 3D printers. It has a robust design and very polished software, with profiles for hundreds of filaments. However:

• It does not include a multicolor system as standard (requires the MMU accessory).

• It does not feature AI or a flow rate sensor.

• Nozzle changes require tools.

It is an excellent machine for those who value reliability and Prusa support, but the P2S is more advanced in terms of automation and ease of use.

Versus Bambu H2D

The Bambu H2D is Bambu's professional 3D printer with a dual extruder. Its purpose is mass production and the simultaneous printing of two colors or materials. It is more expensive and complex. The P2S, on the other hand, is aimed at enthusiast or professional users who want a complete and affordable device. If you don't need a dual print head, the P2S is more than enough.

Pros and cons of the P2S

To help you decide, here we summarize the main strengths and weaknesses of this 3D printer:
