Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab P1S. Store title: "Bambu Lab P1S 3D Printer"[1]Creality K2[2]
Street price (USD; dated snapshot per entry)From $369.00 (base P1S) on the Bambu Lab US store, Aug 2026, against a stated typical price of $399.00; with the P1S AMS 2 Pro Combo variant selected the same page shows $539.00 against a typical $579.00[3][1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Enclosed version of the P1P and mechanically the same motion platform. Three SKUs on one product page: P1S, P1S AMS Combo and P1S AMS 2 Pro Combo (the AMS 2 Pro adds active filament drying). Sibling figures that get mixed up: net weight 12.95 kg (P1S) vs 9.65 kg (P1P); depth 389 mm vs 386 mm; ABS/ASA Ideal (P1S) vs Capable (P1P). Also distinct from the 2026 P2S, which is a different machine (600 mm/s, 110 C bed, 5-inch touchscreen, 14.9 kg)[1][4]Smallest of three K2 machines that share a product page. K2: 260 mm cube, no chamber heating, 100 C bed, 300 C nozzle, 8 GB storage, one air filter, one auxiliary cooling fan, 720p camera, no RFID reader, no Ethernet. K2 Pro: 300 mm cube, 60 C chamber, 110 C bed, RFID, Ethernet, 32 GB. K2 Plus: 350 mm cube, 350 C nozzle, 120 C bed, 30000 mm/s2, dual air filters, auto belt tensioning, 1080p camera, dual-band Wi-Fi. A K2 SE also exists as a separate model[2]
Market position: superseded? successor announced?Still sold in Aug 2026, but Bambu now markets the P2S as "The Classic Evolves" above it in the same enclosed-CoreXY slot[3][5]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm advertised. Bambu's own footnote sets the default printable height in Bambu Studio to 250 mm to prevent heatbed collisions, and notes the collapsible filament-cutter stopper occupies part of the print area when popped out[1]260 x 260 x 260 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 458 mm; package 485 x 480 x 530 mm[1]404 x 436 x 545 mm[2]
Net weight (kg)12.95 kg net, 17.60 kg gross; the AMS Combo ships at 21.60 kg gross and the AMS 2 Pro Combo at 21 kg gross[1]18.3 kg[2]
Frame construction & materialSteel chassis (shared with the P1P) inside plastic and glass panels[1]Not documented
Enclosure: open / enclosed; panel material; door/lidFully enclosed - plastic and glass panels with a glass front door and lid, plus an activated-carbon air filter. No active chamber heater; the chamber temperature regulator fan is closed-loop controlled[1]Enclosed, but with no chamber temperature control - Creality's table gives a max chamber temperature for the K2 Pro and K2 Plus and a dash for the K2. One air filter fitted[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY driven by two stepper motors, each with an independent belt to the printhead; the P1P and P1S share the same motion system[6]CoreXY - Creality groups the K2 series with its CoreXY flagships and quotes 600 mm/s with step-servo motors on the X and Y axes[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree leadscrews belt-driven from a single stepper motor, whole bed moving in Z; manual tramming by three knobs under the bed, no motorised Z-tilt[6]Not documented
Belts (type, width, e.g. Gates?)Rear adjustable belt tensioners with a Belt Tension Monitor[6]Manual belt tensioning (the K2 Plus is auto-adjusted)[2]
Stepper motors (frame size, step angle, brand if known)Not documentedStep-servo motors on the X and Y axes and the extruder (the K2 Plus adds them on Z)[2]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1]600 mm/s max printing speed (manufacturer claim)[2]
Max acceleration (claimed, mm/s²)20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]20000 mm/s2 max acceleration (manufacturer claim)[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive; the service part is the "Stainless Steel Extruder Unit (P1 series)"[6]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)All-metal all-in-one hotend with the nozzle integrated into the heatblock, replaced as a unit; 0.4 mm stainless-steel nozzle included, 0.2/0.6/0.8 mm optional[1][6]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]300 C claimed max nozzle temperature[2]
Heater cartridge power (W)Not documented70 W rated hotend power[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max build-plate temperature[1]100 C max heatbed temperature - the lowest in the K2 family[2]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Nozzle-touch probing using three ceramic force (piezo) sensors mounted under the heatbed - Z homing is done by detecting the force of the nozzle contacting the bed[7][6]Smart auto levelling fitted; unlike the K2 Pro and Plus there is no nozzle AI camera, so there is no automatic flow-rate calibration[2]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - filament run-out sensor[1]Not documented
Multi-material/multi-color capability or official upgrade pathAMS-compatible; sold as P1S AMS Combo and P1S AMS 2 Pro Combo, up to 16 colours with four AMS units[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart-cooling fan plus auxiliary part-cooling fan, control-board fan and chamber temperature regulator fan, all closed-loop controlled (all four are merely Optional on the P1P)[1]One auxiliary cooling fan and one air filter[2]
Chamber/exhaust fan & filtration (activated carbon / HEPA)Chamber temperature regulator fan with an activated-carbon air filter[1]Not documented
Electronics & Power
Total rated power draw100-240 VAC 50/60 Hz; 1000 W at 220 V, 350 W at 110 V[1]Not documented
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[8]Creality OS, a Klipper derivative. Creality publishes the K2 firmware source as CrealityOfficial/K2_Series_Klipper on GitHub under GPL-3.0, last pushed March 2026[9][10][2]
Connectivity, UI & Camera
Display: size, type, touch?2.7-inch 192x64 monochrome screen, not a touchscreen; control by button, app or PC application (P1 series)[6]4-inch touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Button-driven monochrome on-device UI; job setup happens in Bambu Studio or Bambu Handy[6]Touch UI with alarm sounds; no built-in RFID reader[2]
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 (P1 series)[6]Wi-Fi 2.4 GHz, USB drive and a Creality 485 port; no Ethernet. 8 GB eMMC storage[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[1]One chamber camera, 720p at 30 fps[2]
Materials Support
Officially supported filament listIdeal: PLA, PETG, TPU, PVA, PET, ABS, ASA. Capable: PA, PC[1]PLA, PETG, PET, ABS, PLA-CF - a shorter list than the K2 Pro and Plus, which add ASA, PA-CF and PPA-CF[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedNot verified directly. Creality publishes the K2-series firmware as CrealityOfficial/K2_Series_Klipper (GPL-3.0); upstream Klipper ships the verify_heater thermal-runaway check, but whether the stock configuration enables it was not checked here[9][10]
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[11]Creality's US store states "Up to 12-Month Warranty", a 14-day return and refund window and "Lifetime Customer Support" on its printer product pages. The "up to" wording means the term is not uniform across parts[12]

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.
