ClassCOREXYTOOLCHANGER
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab P1P. Bambu documents it alongside the P1S in a single two-column parameters table[1]Snapmaker U1 3D Printer[2]
Street price (USD; dated snapshot per entry)Not documented$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)P1P is the open-frame version; the P1S is the same motion platform in an enclosure with plastic and glass panels. Bambu's own comparison table shows what the P1P lacks: control-board fan, chamber temperature regulator fan, auxiliary part-cooling fan and air filter are all listed "Optional" on the P1P and "Closed Loop Control"/"Activated Carbon Filter" on the P1S. The P1P is also lighter, 9.65 kg vs 12.95 kg, and 386 mm deep vs 389 mm. A P1P Enclosure Kit is sold as a spare part. Filament support differs accordingly: ABS/ASA are "Capable" on the P1P but "Ideal" on the P1S[1]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Market position: superseded?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?Superseded. No longer listed in the Bambu Lab US store 3D-printer collection in Aug 2026 (the collection carries A1, A1 mini, A2L, P1S, P2S, X2D, H2S, H2D, H2C); /products/p1p redirects to the collection page and only P1P spare parts remain in the store sitemap. No live first-party price could therefore be recorded[3][1]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm advertised. Bambu's own footnote limits the default printable height in Bambu Studio to 250 mm to avoid heatbed collisions, and warns that the collapsible filament-cutter stopper takes part of the printing area when popped out[1]270 x 270 x 270 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)386 x 389 x 458 mm (P1P). Bambu prints P1P and P1S dimensions in the same cell - the P1S is 389 x 389 x 458 mm[1]584 x 499 x 730 mm[2]
Net weight (kg)9.65 kg net, 14.30 kg gross[1]18.2 kg[2]
Frame construction & materialOpen frame; Bambu offers printable mod-plates for the side panels[1]Not documented
Enclosure: open / enclosed; panel material; door/lidOpen frame. An official P1P Enclosure Kit exists as a spare part, and the enclosed version of the same platform is sold as the P1S[1][3]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 driven by two stepper motors, each with its own belt to the printhead. Bambu's wiki states the P1P and P1S share the same motion system[4]Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree leadscrews driven from a single stepper motor through a belt; the whole bed drops in Z. There is no motorised Z-tilt - bed tramming is by three manual knobs under the bed[4]Not documented
Belts (type, width, e.g. Gates?)Adjustable belt tensioners at the rear; a Belt Tension Monitor reports when tension drifts out of range[4]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)500 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)20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]20,000 mm/s2 maximum (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)Not documented32 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; Bambu sells a "Stainless Steel Extruder Unit (P1 series)" as the service part[4]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)All-metal all-in-one hotend: the nozzle is integrated into the heatblock and joined to the heatsink by a thin metal tube, so the hotend is replaced as a unit. 0.4 mm stainless-steel nozzle included; 0.2/0.6/0.8 mm optional[1][4]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end 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 limit100 C max build-plate temperature[1]100 °C maximum (manufacturer claim)[2]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[1]Flexible steel sheet with a PEI surface[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Nozzle-touch probing against three ceramic force (piezo) sensors under the heatbed: Z homing works by detecting the force of the nozzle contacting the heatbed. Three manual levelling knobs are also fitted[5][4]Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - filament run-out sensor[1]Filament run-out detection, plus air-printing detection and RFID filament recognition[2]
Multi-material/multi-color capability or official upgrade pathCompatible with AMS and the AMS hub, up to 16 colours with four AMS units[4]Four 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 fitted; the control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan that the P1S has under closed-loop control are all listed as Optional on the P1P[1]Main plus auxiliary part-cooling fans[2]
Electronics & Power
Total rated power drawNot documentedMaximum 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]
Connectivity, UI & Camera
Display: size, type, touch?2.7-inch 192x64 monochrome screen, not a touchscreen - control is by button, app or PC application[4]3.5-inch, 320 x 480 touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Button-driven on-device UI on a 192x64 monochrome panel; most interaction is expected to happen in Bambu Studio or Bambu Handy[4]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi, Bluetooth and Bambu-Bus; microSD card storage; 5 V/1.5 A USB output power[4]Wi-Fi 2.4 GHz (802.11b/g/n) and USB flash drive. No Ethernet listed[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Low-rate chamber monitoring camera, 1280x720 at 0.5 fps, timelapse supported - the 0.5 fps figure is Bambu's own and is far below video rate[1]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 listIdeal: PLA, PETG, TPU, PVA, PET. Capable: PA, PC, ABS, ASA - the open frame is the limiting factor, and the same table upgrades ABS/ASA to Ideal for the enclosed P1S[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.
