Bambu Lab P1S Combo Review – A Powerful, Fast, and Reliable 3D Printer for Professionals
When the Bambu Lab P1S Combo was first introduced, it immediately drew attention for blending high-speed CoreXY motion, auto-calibration, and multi-color printing — all in one enclosed, professional-grade system. For creators who demand both performance and reliability, the P1S Combo represents a major step forward in consumer FDM printing.
Building upon the foundation of the popular P1P and borrowing several innovations from the flagship X1 Carbon, the Bambu Lab P1S 3D Printer brings together industrial-grade engineering with ease of use rarely seen in the desktop segment. Paired with the Automatic Material System (AMS), it supports up to 16 colors or materials, enabling detailed, multi-layered designs without complex manual filament changes.
This Bambu Lab P1S Combo review explores every aspect — from hardware design and setup to print quality, speed, and real-world usability. The goal: to find out if the P1S Combo truly lives up to its reputation as one of the best 3D printers of 2025.

Bambu Lab P1S Design and Build Quality
The first thing you notice about the Bambu Lab P1S is its robust, fully enclosed structure. Measuring 18.72 × 23.01 × 18.72 inches and weighing 47.5 pounds, it exudes the confidence of a machine designed for professional results.
The chassis is constructed from welded steel, enclosed with plastic and glass panels that help retain internal heat and minimize warping — especially when printing materials like ABS, ASA, or PC. The enclosed body also contributes to quieter operation and better print stability.
Inside, the printer features:
- All-metal hotend (up to 300°C) for advanced filament compatibility
- CoreXY motion system for high-speed precision
- Enhanced cooling system with closed-loop control fans
- Activated carbon filter for safer high-temperature filament printing
Unlike most open-frame printers, the Bambu Lab P1S enclosed 3D printer is built to deliver consistent results across a range of materials. The interior lighting, tidy cable routing, and built-in camera for remote monitoring underscore the attention to detail that defines Bambu Lab’s design philosophy.
Setup and Calibration
One of the main selling points of the Bambu Lab P1S Combo is how effortlessly it sets up. From unboxing to your first print, the process takes less than 15 minutes — an impressive feat for such a capable machine.
Once powered on, the printer automatically performs:
- Auto Bed Leveling (ABL)
- Vibration Compensation
- Pressure Advance Tuning
These automated steps eliminate manual calibration, ensuring accurate first layers and smoother extrusion across prints.
Using the Bambu Studio slicer, users can send files wirelessly, adjust print parameters, and monitor progress. The Bambu Handy mobile app further enhances convenience, allowing you to check print status remotely via Wi-Fi and even watch live footage through the built-in camera.
For both beginners and professionals, this “just works” experience makes the P1S Combo one of the most user-friendly yet technically advanced printers in its class.
Bambu Lab P1S Printing Speed and Performance
Speed is the crown jewel of the Bambu Lab P1S. With a maximum print speed of 500 mm/s and acceleration of 20,000 mm/s², it’s among the fastest FDM printers available.
In benchmark tests, it can print a 3D Benchy model in under 20 minutes, with minimal loss of surface quality. This is made possible by the combination of a CoreXY motion system, vibration compensation, and pressure advance algorithms, all fine-tuned by Bambu Lab’s firmware.
Even when printing complex geometries, motion stability remains excellent. Edges are crisp, surfaces are smooth, and layer consistency is impressive — even at high speed.
Compared with typical printers that slow down for quality, the P1S 3D printer manages to maintain precision without sacrificing time.
Multi-Color and Multi-Material Printing with AMS
The Automatic Material System (AMS) transforms the Bambu Lab P1S Combo from a single-material printer into a creative powerhouse. Each AMS unit can hold four filaments, and you can stack up to four AMS units for a total of 16 colors or materials.
The AMS automatically switches between filaments during printing, enabling features such as:
- Color gradients or complex logos
- Functional multi-material parts (e.g., PLA with TPU joints)
- Soluble supports using PVA or PET
The transition is seamless, though each filament swap includes a brief purge cycle. While this adds slight print time, the creative possibilities far outweigh the minor delay.
Moreover, the AMS maintains filament quality with its sealed, humidity-controlled storage, essential for moisture-sensitive materials like nylon (PA) or TPU.
Material Compatibility and Temperature Control
The Bambu Lab P1S supports a broad range of filaments, giving users flexibility to print functional or artistic models alike:
| Ideal Materials | Capable Materials | Not Recommended |
|---|---|---|
| PLA, PETG, TPU, PVA, PET, ABS, ASA | PA (Nylon), PC | Carbon/Glass Fiber Reinforced Polymers |
The 300°C all-metal hotend and enclosed chamber allow reliable printing with temperature-sensitive materials.
Thermal stability is excellent — the chamber fans and toolhead cooling system use closed-loop control, adjusting automatically to maintain consistent airflow and temperature.
This makes the P1S enclosed 3D printer ideal for functional parts requiring durability and heat resistance.
Print Quality and Surface Finish
Speed often comes at the cost of quality, but the Bambu Lab P1S Combo defies that expectation.
Layer adhesion is strong, dimensional accuracy is tight, and fine details are crisp. Overhangs up to 60° are well-handled, and bridges print cleanly without sagging. The smoothness of curved surfaces and sharpness of small text models stand out even in default profiles.
Because calibration is automated, consistency remains excellent across multiple prints — a critical advantage for professional workflows.
In side-by-side comparisons, the P1S print quality is on par with the X1 Carbon and outperforms most competitors in the same price range.
Software and Ecosystem: Bambu Studio and Bambu Handy
The Bambu Lab ecosystem centers on two key tools — Bambu Studio and Bambu Handy.
Bambu Studio (based on PrusaSlicer) includes both beginner and expert modes. It offers:
- Pre-tuned profiles for Bambu filaments
- Multi-color management for AMS
- Real-time device monitoring
- Integration with pressure advance and flow calibration
Advanced users can edit G-code or fine-tune layer-specific settings, while beginners can rely on the default profiles for plug-and-play reliability.
The Bambu Handy app adds convenience, enabling real-time print control, monitoring, and even timelapse recording via the built-in camera.
Together, these tools provide a seamless, modern workflow that elevates the entire P1S user experience.
Noise, Cooling, and Filtration Performance
Thanks to its enclosed design and controlled fans, the Bambu Lab P1S operates at a comfortable 45–50 dB, making it suitable for office or home use.
The activated carbon filter absorbs fumes and odors from materials like ABS, while the closed-loop fan system maintains consistent cooling across different filament types.
These environmental controls ensure not only cleaner prints but also a safer and quieter working environment — something not every high-speed 3D printer can claim.

Maintenance and Reliability
Maintenance is refreshingly minimal. The printer’s auto-calibration, enclosed chamber, and well-protected motion components keep dust and wear under control.
Regular maintenance includes:
- Wiping the build plate
- Cleaning the nozzle when needed
- Replacing the carbon filter periodically
The AMS requires occasional filament path cleaning, but overall, upkeep is simple and quick.
Firmware updates are easily managed through Bambu Studio, ensuring continued performance optimization and feature updates.
In long-term testing, users report consistent print quality and near-zero mechanical failures after hundreds of hours — a hallmark of reliable engineering.
