The Bambu Lab P1S is a fully enclosed CoreXY 3D printer with a 256 × 256 × 256 mm build volume, offering fast print speeds up to 500mm/s and 20,000 mm/s² acceleration. It supports a wide range of materials, including PLA, PETG, TPU, ABS, and ASA, and includes features like auto-bed leveling, a built-in camera for remote monitoring and timelapses, and optional AMS support for up to 16-color printing. An activated carbon filter helps reduce odors from materials like ABS and ASA. With a 300°C hotend, advanced cooling, and simple 15-minute setup, the P1S is designed for both beginners and experienced users, and can be controlled remotely via Bambu Studio and Bambu Handy.
What is the print quality and performance of the Bambu Lab P1S CoreXY 3D Printer?
The Bambu Lab P1S delivers high-quality prints at speeds up to 500mm/s using a CoreXY system with vibration compensation and input shaping. It maintains dimensional accuracy and clean layer stacking across materials, with minimal difference in quality between standard (200–300mm/s) and high-speed prints. It prints fine details at 0.08mm layer height using the stock 0.4mm nozzle, with optional nozzles from 0.2mm to 0.8mm.
The Bambu Lab P1S reaches speeds of 500mm/s with 20,000mm/s² acceleration and offers three modes: standard, sport (124% faster), and ludicrous (164% faster). A Benchy prints in 18 minutes at full speed versus 26 at normal speed. Most prints finish in 1–2 hours — about four times faster than entry-level printers. The slicer’s volumetric speed limit ensures reliable material flow across filament types.
Real-world prints show the P1S's versatility: a multi-color Baby Yoda was printed in 2h 36m (0.8mm layer height); a multi-part action figure was printed in 2h 43m (0.16mm layer height, 3 wall perimeters); nylon RC car gears in 1h 13m; ASA tape dispensers in 1h 17m; and TPU car spoilers in 5h 47m at 40mm/s.
The Bambu Lab P1S delivers consistent print quality through key mechanical features: auto bed leveling for a perfect first layer, a direct-drive extruder for precise filament control (especially with flexibles), and an enclosed design for chamber temperature stability. Its cooling system — hotend, front cover, and auxiliary part cooling fans — supports various materials. Vibration compensation and pressure advance reduce artifacts, ensuring clean results at any speed or complexity.
Does Bambu Lab P1S use a direct-drive extruder?
Yes — it has a direct-drive extruder, offering superior control over filament extrusion and retraction of flexible filaments.
How does Vibration Compensation and Pressure Advance work?
Before printing, the P1S measures X/Y axis resonant frequencies and applies input shaping with an advanced control algorithm to avoid them, reducing ringing. Pressure Advance adjusts flow based on movement — boosting during acceleration and retracting on deceleration — to maintain consistent line width, even at 500mm/s.
How does the AMS detect and handle filament run-outs or tangles during multi-colour prints on the Bambu Lab P1S, and what recovery mechanisms are built in to prevent failed jobs?
The AMS uses 3 sensors:
Optical gates in each feeder and hub detect filament presence; if empty, it auto-switches spools or pauses for user input.
A toolhead switch confirms filament arrival; if triggered mid-print, it signals a run-out and pauses.
A tension module monitors drag; excess force triggers a “tangle detected” pause.
During pauses, the AMS retracts, cuts, and purges filament to prevent oozing or layer shifts before resuming.

Which filaments can you use with the Bambu Lab P1S?
The Bambu Lab P1S supports over 8 printing filaments — PLA, PETG, TPU, PVA, PET, ABS, ASA, Nylon (PA), and Polycarbonate (PC) — thanks to its enclosed chamber, 300°C all-metal hotend, and 100°C heated print bed. The fully enclosed printing chamber for materials like ABS and ASA, while an activated carbon filter reduces odors and emissions.
The included textured PEI plate offers good adhesion for most materials, but Bambu Lab recommends their Engineering Plate for better results with high-temp filaments like polycarbonate and nylon.
For optimal results, flexible filaments like TPU should be printed at 40mm/s to avoid jams during loading. Nylon benefits from reduced wall speeds around 75mm/s for better layer adhesion. Carbon- or glass-fiber filaments require a hardened steel nozzle, as the stock 0.4mm stainless steel nozzle wears quickly with abrasives.
The Bambu Lab P1S supports both Bambu Lab and third-party filaments. Bambu filaments include RFID tags for automatic detection of type, color, and remaining amount. Third-party filaments work well but require manual setup in Bambu Studio and lack auto-identification.

What is the build volume of the Bambu Lab P1S?
The Bambu Lab P1S has a 256 × 256 × 256 mm build volume, shared with the P1P and X1 Carbon. Bambu Studio limits the default printable height to 250 mm to avoid bed collisions, but the full height is accessible with safety precautions. The collapsible filament cutter stopper slightly reduces usable space when extended.
What is the difference between the Bambu Lab P1S and Creality K1 Max, Prusa Core One and Flashforge Adventurer 5M?
Bambu Lab P1S — enclosed CoreXY with 256 × 256 × 256 mm build, 300 °C nozzle, 100 °C bed, activated-carbon filtration, integrated chamber camera, and optional AMS for multi-material — aimed at balanced speed (≤500 mm/s travel) and turnkey usability.
In contrast:
Creality K1 Max — wins on build volume (300³ mm) and headline speed (≤600 mm/s) plus AI LiDAR; loses the AMS-style multi-material ecosystem and has less clearly integrated filtration specifics compared with P1S’s enclosed, filtered setup.
Prusa Core One — wins on heated chamber (~55 °C), 120 °C bed, and load-cell first-layer automation; loses on build volume (250 × 220 × 270 mm vs 256³), lacks an included camera (optional), and doesn’t publish a comparable headline speed.
Flashforge Adventurer 5M — wins on travel speed (≤600 mm/s); loses enclosure/filtration, has a smaller volume (220³ mm), and a lower nozzle ceiling (280 °C vs 300 °C).
Flashforge Adventurer 5M Pro — wins on enclosure with HEPA+carbon filtration and ≤600 mm/s travel; loses on build volume (220³ mm) and nozzle temp (280 °C vs 300 °C) and lacks an AMS-like multi-material option.
Buy the Bambu Lab P1S, if you want an enclosed, camera-equipped 256³ workhorse with 300 °C headroom and a drop-in multi-material path (AMS);
Buy the Creality K1 Max for sheer size/speed;
Choose the Prusa Core One for chamber heat, broader material capability and first-layer automation;
Buy the Flashforge Adventurer 5M/5M Pro for lighter-duty, smaller-volume use (Pro adds enclosure + filtration).

What connectivity options are available on the Bambu Lab P1S?
The Bambu Lab P1S supports Wi-Fi, Bluetooth (for pairing), and a MicroSD slot for remote printing. Setup involves connecting to Wi-Fi and linking a Bambu Lab account via the Bambu Handy app, enabling communication with Bambu Studio and the mobile app. A "LAN only" mode is available for local-only use, with access controlled by a printer-displayed code.
What software is offered with the Bambu Lab P1S?
The Bambu Lab P1S runs on a software ecosystem built around Bambu Studio, a slicer based on PrusaSlicer. It includes material presets, multicolor painting for AMS, automatic filament-based settings, and flow calibration for optimized prints. The Bambu Handy mobile app (iOS/Android) offers remote control, live camera monitoring, and print management. Both apps connect to MakerWorld, Bambu Lab’s model library for direct downloads.
While the P1S supports third-party slicers via Bambu Connect, native tools offer the best experience — especially for AMS and high-speed printing.
How does Bambu Studio’s project-based workflow manage multi-plate assemblies and shared resources compared with traditional slicers like PrusaSlicer?
Bambu Studio bundles every part, plate, filament preset, and slicer setting into a single 3MF “project.”
Plates: tabbed views let you drag models between plates, auto-re-slice just the active plate, and queue plates sequentially to one or many printers — traditional slicers treat each plate as a separate file.
Shared resources: one project-level library holds build-plate profiles, colors, AMS mappings, and assembly metadata, so changes propagate to every plate instantly; PrusaSlicer stores these per-file, requiring manual duplication.
What is the design and build quality of the Bambu Lab P1S?
The Bambu Lab P1S features a fully enclosed, durable design with plastic side panels, a glass door and top, and a gunmetal finish. Built on a welded steel chassis for stability, it measures 389 × 389 × 458 mm (15.3 x 15.3 x 18 inches) and weighs 12.95 kg (28.5 lbs).
The glass door offers clear print visibility, and the removable glass top allows ventilation or supports the optional AMS. While the P1S has a sleek, functional design, it uses plastic panels instead of the aluminum found on the higher-end X1 Carbon.
The Bambu Lab P1S uses a CoreXY system with carbon X-axis rods and LMU8-bearing linear rods for Y and Z movement, achieving speeds up to 500 mm/s and 20,000 mm/s² acceleration. Vibration damping, input shaping, and semi-automatic belt tensioning within the precision control system of the Bambu Labenable rapid acceleration from zero to 500 mm/s in 0.025 seconds. The Bambu P1S prints up to 4× faster than bed-slingers without quality loss. A direct-drive extruder ensures precise and consistent extrusion.
Three Z-axis lead screws ensure stable bed movement, while the direct-drive extruder delivers precise filament control for clean, accurate prints.
The Bambu Lab P1S includes user-friendly features like a built-in LED light for chamber visibility, though some users find it dim.
The rear spool holder supports standard filament rolls, feeding through a PTFE tube to the print head when AMS isn't used. An "excess chute" expels waste filament during color changes but lacks a collection container. The enclosed design maintains stable temperatures for materials like ABS and ASA, while a carbon filter reduces odors. Maintenance is easy via the glass door, providing access to key components.
The cooling system includes an auxiliary part fan, chamber regulator fan, and control board fan to manage temperatures across different materials.
The power supply is made by MornSun, a reputable supplier.
The main controller board is a proprietary Bambu Lab design with integrated motor drivers and an aluminum heatsink. Connectors lack thermal adhesive, making repairs easier.
Power Supply Unit:
The front cooling shroud uses a magnetic quick-release with built-in fan mounts. The visible, modular filament feed assembly and hotend are made from precision-built components and can be easily removed or disassembled.
