Bench unitThe Bambu Lab P1S is a superb enclosed FDM printer that hits a sweet spot between speed, print quality, and affordability. Its rigid CoreXYZ frame, effective auto-leveling, and enclosed chamber make it a versatile machine capable of handling both simple PLA prints and more demanding materials like ABS and ASA. While the AMS add-on and cloud-dependent app leave some room for improvement, the P1S remains one of the best values in the prosumer 3D printing space today.
Measured on our bench
The Bambu Lab P1S is a high-speed FDM 3D printer that builds on the foundation established by the earlier P1P, wrapping the same capable core in a fully enclosed chassis. This enclosure is not merely cosmetic; it stabilizes the internal chamber temperature, making the printer far more reliable when working with warp-prone engineering materials like ABS, ASA, and PETG-CF. Inside that enclosed frame sits a CoreXY motion system paired with high-torque stepper motors, allowing the P1S to reach print speeds and accelerations that dramatically outpace typical consumer-grade Bendy-frame printers, all while maintaining tight dimensional accuracy on finished parts.
At the heart of the P1S is the same Micro Lidar-assisted auto bed leveling and flow calibration system found in Bambu Lab's higher-end X1 series, meaning users get automatic first-layer compensation, vibration compensation, and input shaping without manual tuning. The all-metal hotend is capable of hitting 300°C, opening the door to advanced filaments such as nylon, PC, and carbon-fiber-reinforced blends, while the direct-drive extruder ensures consistent filament feeding for flexible materials like TPU. A tempered glass build plate with a textured PEI-style surface option, an active carbon and HEPA filtration system, and quiet cooling fans round out a machine designed to run intensive, unattended, multi-hour prints safely inside a home or office.
Connectivity and ecosystem integration are where the P1S distinguishes itself further, running on Bambu Studio slicing software with cloud-based monitoring, timelapse recording, and remote control through the Bambu Handy mobile app. The printer supports the AMS (Automatic Material System) for multi-color and multi-material printing, letting users swap between up to sixteen spools using multiple units without manual filament changes. Combined with a compact footprint, a built-in camera for live print monitoring, and Bambu Lab's continually updated firmware, the P1S serves makers, small businesses, and prosumers who want the speed and multi-material versatility of premium 3D printing hardware without stepping up to the full X1 Carbon price point.
Coming from a basic Ender 3, the P1S feels like a leap into the future. Prints finish in a fraction of the time and the surface quality is fantastic even at high speeds. The enclosure means I can finally print ABS parts without warping.
The printer itself performs excellently — fast, quiet, and accurate. My only gripe is how tied everything is to Bambu's app and cloud services. Still, the print results speak for themselves.
Adding the AMS unit lets me print multi-color models with zero hassle. Combined with the P1S's speed, this has completely changed my workflow for functional prototypes and multi-material projects.
I've had mine running almost daily for months with very few issues. The auto bed leveling and flow calibration save me tons of time. Just wish the base kit included more spare nozzles.
