Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab P2S; spec sheet header "P2S Spec Sheet"[1]Snapmaker U1 3D Printer[2]
Street price (USD; dated snapshot per entry)From $549.00 on the Bambu Lab US store, Aug 2026; the product page shows $749.00 with the P2S Combo variant selected[3][4]$849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Two SKUs: P2S and P2S Combo (with the 2nd-generation AMS, which adds filament drying). Do not carry P1S figures across - the P2S differs on nearly every headline number: 600 vs 500 mm/s, 110 vs 100 C bed, hardened-steel vs stainless nozzle, 5-inch 854x480 touchscreen vs 2.7-inch monochrome, 14.9 vs 12.95 kg, 1920x1080 30 fps camera vs 1280x720 at 0.5 fps[1][5]An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[2]
Market position: superseded? successor announced?Current model, marketed by Bambu as "The Classic Evolves" - the direct replacement for the P1S, which is still sold below it[3]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm (manufacturer figure)[1]270 x 270 x 270 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)392 x 406 x 478 mm[1]584 x 499 x 730 mm[2]
Net weight (kg)14.9 kg net[1]18.2 kg[2]
Frame construction & materialPlastic and steel chassis with a plastic and glass outer frame[1]Not documented
Enclosure: open / enclosed; panel material; door/lidFully enclosed with a door sensor and an activated-carbon (granulated coconut shell) filter with VOC and particulate filtration. No active chamber heater is listed[1]Open as sold; a top cover is an optional accessory that raises the supported material range[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY - Bambu positions the P2S as the successor to the P1S platform. The spec sheet itself does not name the kinematics[1][4]Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[2]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1]500 mm/s maximum toolhead speed (manufacturer claim)[2]
Max acceleration (claimed, mm/s²)20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]20,000 mm/s2 maximum (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)40 mm3/s standard-flow hotend, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[1]32 mm3/s maximum hotend flow (manufacturer claim)[2]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput shaping with an accelerometer, run as a calibration routine[2]
Extrusion Pressure Control
Pressure advance (Klipper) / linear advance (Marlin) supported?Not documentedPressure advance, with automatic flow compensation calibration[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive with hardened-steel extruder gears, driven by a Bambu Lab high-precision permanent-magnet synchronous motor rather than a plain stepper; built-in filament cutter[1]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]300 °C maximum (manufacturer claim)[2]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedStainless steel as standard; hardened steel needed for fibre-filled grades[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heatbed temperature[1]100 °C maximum (manufacturer claim)[2]
Bed surface (material, texture, coating), single/double-sidedFlexible steel plate; Textured PEI plate included, Smooth PEI Plate and Cool Plate SuperTack supported[1]Flexible steel sheet with a PEI surface[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedMesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, tangle sensor, door sensor; filament odometry with AMS[1]Filament run-out detection, plus air-printing detection and RFID filament recognition[2]
Multi-material/multi-color capability or official upgrade pathNot documentedFour toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart-cooling fan, hotend cooling fan and auxiliary part-cooling fan, all closed-loop controlled[1]Main plus auxiliary part-cooling fans[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Motion controller is a dual-core Cortex-M4 plus a single-core Cortex-M7; application processor is a quad-core 1.5 GHz ARM A7 with a 2 TOPS neural processing unit. Board model and chip markings not published[1]Not documented
Total rated power draw100-120 VAC / 200-240 VAC 50/60 Hz; max 1200 W at 220 V, 1000 W at 110 V; steady state 200 W printing PLA[1]Maximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Closed-source proprietary firmware - not a Klipper or Marlin derivative, and no printer-firmware source is published. The bambulab GitHub organisation carries 11 repositories (Bambu Studio, wxWidgets/boost/ffmpeg forks, the wiki); none is printer firmware. Updates are delivered over the air via Bambu Studio / Bambu Handy[6]Klipper[2]

Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Built-in camera, 1920x1080 at 30 fps - a real video-rate camera, unlike the 0.5 fps unit in the P1 series[1][5]2 MP built-in chamber camera for live view[2]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery supported; mechanism not published[2]
Materials Support
Officially supported filament listPLA, PETG, ABS, ASA, TPU, support materials, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[1]Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[2]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[7]Not documented

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
