The Bambu Lab P1S 3D printer delivers high-speed performance with exceptional print quality in a fully enclosed design. Built on a CoreXY motion system, the P1S achieves printing speeds of 500mm/s with 20,000 mm/s² acceleration while maintaining precision through advanced vibration compensation technology. This enclosed system creates a controlled environment for printing various materials including PLA, PETG, TPU, ABS, and ASA within its 256 x 256 x 256 mm build volume.
The Bambu Lab P1S excels through its combination of automation and versatility. Its fully automatic bed leveling system ensures perfect first layers without manual adjustment, while the built-in camera enables remote print monitoring and timelapse creation. When paired with the optional Automatic Material System (AMS), the P1S supports multi-color printing with up to 16 colors when equipped with four AMS units. The integrated activated carbon filter reduces odors when printing materials like ABS and ASA.
This printer serves both beginners and experienced makers seeking reliability without extensive tinkering. The P1S sets up in 15 minutes and works immediately out of the box, eliminating the learning curve often associated with 3D printing. Through the Bambu Studio software and Bambu Handy mobile app, users can control prints remotely and monitor progress from anywhere. With its maximum hotend temperature of 300°C and comprehensive cooling system featuring auxiliary part cooling, chamber temperature regulation, and control board fans, the P1S handles everything from decorative models to functional prototypes with consistent results.
The Bambu Lab P1S delivers exceptional print quality through its advanced CoreXY motion system combined with vibration compensation and input shaping technologies. This printer produces prints with clean, even finishes and precisely stacked layers even at high speeds. The P1S achieves this quality consistently across various materials while maintaining dimensional accuracy. Print tests show no noticeable quality difference between normal speed (200-300mm/s) and high speed (500mm/s) prints, with layers described as "very neatly stacked" in both scenarios. The printer handles fine details effectively, printing at layer heights as low as 0.08mm with the stock 0.4mm nozzle for detailed work like multi-color models.
Performance specifications of the Bambu Lab P1S set it apart with maximum print speeds of 500mm/s and acceleration up to 20,000mm/s². The printer offers three speed modes: standard, "sport" (124% faster than standard), and "ludicrous" (164% faster than standard). This translates to practical time savings, with a standard 3D Benchy printed in just 18 minutes at maximum speed compared to 26 minutes at normal speed. Most prints complete in 1-2 hours, approximately four times faster than entry-level printers. The P1S maintains reliability during these high-speed prints, with the slicer's volumetric speed limitation acting as a built-in throttle to ensure proper material flow based on filament type.
Real-world examples demonstrate the P1S's versatility across applications. A multi-color Baby Yoda painting printed with 0.08mm layers took 2 hours and 36 minutes with results described as "super smooth." An action figure with multiple parts printed in 2 hours and 43 minutes using 0.16mm layers and 3 walls, producing "buttery smooth" layers. Technical materials perform well too, with Nylon gears for RC cars printed in 1 hour and 13 minutes, ASA tape dispensers in 1 hour and 17 minutes, and TPU car spoilers in 5 hours and 47 minutes at a reduced 40mm/s for optimal flexibility.
The mechanical features of the Bambu Lab P1S contribute significantly to its print quality. The fully automatic bed leveling system ensures perfect first layers without manual adjustments. The direct-drive extruder provides precise control over filament flow, particularly beneficial for flexible materials. The enclosed design maintains stable temperatures, while the comprehensive cooling system—including hotend fan, front cover fan, and auxiliary fan—ensures proper cooling across different materials. Active vibration compensation and pressure advance technologies work together to eliminate common print artifacts, resulting in consistent, high-quality prints regardless of complexity or speed settings.
Yes — it has a direct-drive extruder, offering superior control over filament extrusion and retraction of flexbile filaments.
The control algorithm works as follows: the printer rattles X/Y axes pre-print to measure resonant frequencies; firmware then applies input-shaping offsets so moves avoid those frequencies, eliminating ringing. Pressure Advance predicts nozzle pressure—firmware boosts flow on acceleration and retracts on deceleration—keeping line width constant even at 500 mm/s. This ensures precise and consistent extrusion.
The AMS uses 3 sensor stages:
During any pause the AMS retracts, cuts, and purges residual filament so printing can safely restart without layer shifts or oozing.

The Bambu Lab P1S supports 8 filament types through its fully enclosed printing chamber, all-metal hotend reaching 300°C, and heated build plate with 100°C maximum temperature. The 8 filament types are: PLA, PETG, TPU, PVA, PET, ABS, ASA, PA (Nylon) and PC (Polycarbonate). The enclosed chamber of the Bambu Lab P1S creates a stable temperature environment, making it particularly well-suited for printing ABS and ASA compared to open-frame printers. This enclosed design combined with the activated carbon filter reduces odors and potentially harmful emissions when printing these materials.
Certain materials require specific adjustments for optimal results with the Bambu Lab P1S. TPU printing performs best at reduced speeds around 40mm/s rather than the default settings, as tests showed it can occasionally get hung up in the extruder gears during loading. Nylon prints achieve stronger layer adhesion when printed at reduced wall speeds of approximately 75mm/s rather than high speed. The printer isn't recommended for carbon-fiber or glass-fiber reinforced filaments without first upgrading to a hardened steel nozzle, as the standard 0.4mm stainless steel nozzle will wear prematurely with these abrasive materials.
The Bambu Lab P1S works with both proprietary Bambu Lab filaments and third-party materials without restrictions. Bambu Lab filaments include RFID tags that enable the printer and Automatic Material System (AMS) to identify the type, color, and remaining quantity of filament automatically. Third-party filaments function perfectly well but lack the automatic identification features. Users configure settings for non-Bambu filaments in the Bambu Studio software, and when used with the AMS, these filaments operate similarly to official spools.
The hardware features of the Bambu Lab P1S expand its material compatibility significantly. The direct-drive extruder provides precise control for flexible filaments like TPU. The comprehensive cooling system incorporates three key components: an auxiliary part cooling fan, chamber regulator fan, and control board fan, ensuring proper temperature management for different materials. The textured PEI build plate included with the printer provides good adhesion for most materials, though Bambu Lab recommends purchasing their Engineering Plate separately for optimal results with high-temperature filaments like polycarbonate and nylon. The 0.4mm stainless steel nozzle comes standard, with optional 0.2mm, 0.6mm, and 0.8mm nozzles available for different applications.
The Bambu Lab P1S offers a cubic build volume of 256 x 256 x 256 mm (10 x 10 x 10 inches), providing ample space for both recreational and functional 3D printing projects. This build volume is identical across Bambu Lab's core printer lineup, including the P1P and X1 Carbon models. For safety considerations, the default printable height in Bambu Studio is set to 250mm to prevent potential heat bed damage from collisions, though users can access the full 256mm height by following safety instructions in the Bambu Lab wiki. The collapsible filament cutter stopper will occupy part of the printing area when extended, which users should account for when utilizing the entire build space.
| 3D Printer Model | Build Volume |
|---|---|
| Bambu Lab P1S | 256 x 256 x 256 mm |
| Bambu Lab X1 Carbon | 256 x 256 x 256 mm |
| Bambu Lab P1P | 256 x 256 x 256 mm |
| Bambu Lab A1 Mini | 180 x 180 x 180 mm |
| Creality K1 Max | 300 x 300 x 300 mm |
| Prusa Core One | 250 x 220 x 270 mm |
| FlashForge Adventurer 5M | 220 x 220 x 250 mm |
The Bambu Lab P1S's 256 x 256 x 256 mm cubic build volume strikes an optimal balance between desktop footprint and printing capacity. Unlike the rectangular build volumes of competitors like the Prusa Core One (250 x 220 x 270 mm) and FlashForge Adventurer 5M (220 x 220 x 250 mm), the P1S offers uniform dimensions that maximize usable space without wasted areas. This cubic design proves particularly advantageous for printing large, symmetrical objects and multi-part assemblies. While the Creality K1 Max provides 17% more volume at 300³ mm, the P1S delivers sufficient capacity for 95% of typical printing projects while maintaining excellent print quality through its enclosed chamber design. Compared to the compact A1 Mini's 180³ mm volume, the P1S offers 2.3x more printing space, making it suitable for both hobbyist and small production workflows.
Print examples demonstrate the practical capabilities of the Bambu Lab P1S build volume. Reviewers have printed detailed wearable masks utilizing much of the available space, including a multi-color Pumpkin Girl mask (33-hour print time) and a two-color Droid mask assembled from multiple sections (40-hour total print time). Functional prints showcase the versatility of this build volume, including a Dragon phone holder in recycled PETG (1 hour 52 minutes). The combination of the substantial build volume with the high print speeds of the Bambu Lab P1S allows for completing larger projects efficiently, making it suitable for both hobbyist and small production environments.
The Bambu Lab P1S features a monochrome dot-matrix screen with a directional pad (D-pad) for navigation rather than a touchscreen interface. This control panel displays essential information including current nozzle and print bed temperatures, remaining print time, and provides access to printer functions through menu navigation. The filament loading process requires heating the hotend using the down arrow with waves icon, inserting filament through the Bowden tube until it stops, then pressing the advance filament button (arrows with an E) multiple times until material extrudes from the nozzle. For filament unloading or color changes, a dedicated unload option handles the entire process automatically without user intervention beyond menu selection.
The Bambu Lab P1S includes comprehensive calibration controls accessible through its interface. The printer performs a thorough 15-minute calibration during initial setup, with an option to run a shorter 5-minute calibration before each print job. These calibration routines include auto-bed leveling, vibration compensation, and semi-automatic belt tensioning with no manual adjustments required. The printer intentionally omits z-height adjustment options as the system handles this automatically. During printing, users can adjust speed directly from the control panel, selecting between normal speed, "Sport" mode (124% faster than normal), or "Ludicrous" mode (164% faster than normal). For prints using the Automatic Material System (AMS), the interface includes a dedicated "AMS retry" button to resolve filament issues when the material becomes stuck or runs out.
The Bambu Lab P1S features 3 connectivity options for flexible printer operation. At its core, the printer integrates Wi-Fi for network connectivity, Bluetooth for initial device pairing, and a MicroSD card slot required for remote printing functionality. During setup, users connect the Bambu Lab P1S to their wireless network and link it to their Bambu Lab account through the Bambu Handy mobile app, establishing the communication pathway between the printer and both Bambu Studio software (for computers) and the mobile app (for smartphones). For users prioritizing data privacy, the Bambu Lab P1S offers a "LAN only" mode that restricts all communication to the local network without cloud connectivity, using an access code displayed on the printer screen for authentication.
The Bambu Lab P1S operates through a complete software ecosystem centered on Bambu Studio, a specialized slicing program derived from PrusaSlicer. This desktop application offers comprehensive features including material-specific presets, multicolor painting tools for Automatic Material System (AMS) compatibility, and automatic parameter configuration based on the detected filament types. Bambu Studio integrates flow dynamics calibration tools that optimize print quality, and automatically applies proper settings for Bambu Lab filaments. Complementing this desktop experience, the Bambu Handy mobile app for iOS and Android provides remote printer control, live monitoring through the built-in 720p camera, and print job management from anywhere. Both applications connect to MakerWorld, Bambu Lab's model repository platform where users browse and download printable models directly within the software interface.
The software capabilities extend the Bambu Lab P1S functionality through cloud services and firmware features. Users remotely start prints, monitor progress through the camera feed, adjust fan speeds and temperatures, and generate timelapse videos automatically stored on the microSD card. Regular firmware updates delivered through the Bambu Handy app enhance the printer with features like motor noise cancellation, remote SD card file browsing, print statistics tracking, and optimization technologies including active vibration compensation and pressure advance. The Bambu Lab P1S supports third-party slicers through Bambu Connect, though the native software provides the most integrated experience, particularly for managing multicolor printing with the AMS system and utilizing the printer's high-speed modes.
Bambu Studio bundles every part, plate, filament preset, and slicer setting into a single 3MF “project.”
The Bambu Lab P1S showcases a fully enclosed design with durable material made to support long-term use, featuring plastic side panels complemented by a glass door and top, all finished in a textured gunmetal color. Built upon a welded steel chassis for stability, the printer measures 389 x 389 x 458 mm (15.3 x 15.3 x 18 inches) and weighs 12.95 kg (28.5 lbs). The glass door provides clear visibility of prints in progress, while the removable glass top serves two purposes: enabling ventilation when needed and creating a stable platform for the optional Automatic Material System (AMS). The Bambu Lab P1S delivers a premium appearance with practical functionality, though it uses plastic enclosure panels rather than the aluminum found on the more expensive X1 Carbon model.
The CoreXY motion system of the Bambu Lab P1S incorporates high-quality components that deliver exceptional performance. The printer employs carbon rods for X-axis movement and linear rods with LMU8 bearings for Y-axis and Z-axis travel, enabling precise positioning at speeds up to 500 mm/s with acceleration reaching 20,000 mm/s². This advanced motion system, combined with vibration damping input shaping technology and a semi-automatic belt tensioning system, allows the Bambu Lab P1S to produce prints up to four times faster than traditional bed-slinger printers without sacrificing quality. Three Z-axis lead screws move the heated bed with consistent stability, while the direct-drive extruder provides precise control over filament flow for clean, accurate prints.
The Bambu Lab P1S integrates practical design elements that enhance usability during operation and maintenance. A built-in LED light illuminates the print chamber, though some users report it provides minimal brightness. The rear-mounted spool holder accommodates standard filament rolls when not using the AMS system, with the filament feeding through a PTFE tube to the print head. For material changes, the printer includes an "excess chute" at the rear that expels waste filament during color transitions, though it lacks an integrated collection container. The enclosed design creates a controlled print environment that maintains consistent temperatures for high-temperature materials like ABS and ASA, with the activated carbon filter helping to reduce odors during printing. Access for maintenance is straightforward through the glass door, allowing users to reach the print head, bed, and internal components when needed.
The Bambu Lab P1S ships in a mostly assembled state, requiring 15 minutes of setup time to prepare for first prints. Setup involves removing shipping protections (including cardboard from the tool head, foam from the excess chute, and zip ties securing the toolhead), installing the spool holder and LCD screen using the included Allen key, and connecting the AMS if purchased with the Combo version. The Bambu Lab P1S includes everything needed to start printing immediately, with sample filament provided for testing the pre-loaded models stored on the MicroSD card. The printer's quick start guide walks users through the installation process, ensuring a smooth transition from unboxing to printing.
