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 Plus[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]$999.00 on store.creality.com, Aug 2026[4]
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][5]Largest and only fully specified K2. It is the only one with a 350 C nozzle, a 120 C bed, 30000 mm/s2 acceleration, step-servo motors on Z as well as X/Y, automatically adjusted belt tension, two auxiliary cooling fans, two air filters, a 1080p chamber camera, dual-band Wi-Fi and a 4.3-inch screen. Its "smart auto levelling" is listed as arriving via firmware update rather than shipping enabled, unlike the K2 and K2 Pro. A separate K2 SE model also exists[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Market position: superseded?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][6]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]350 x 350 x 350 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 458 mm; package 485 x 480 x 530 mm[1]495 x 515 x 640 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]35 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 with chamber temperature control up to 60 C and two air filters[2]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented60 C max chamber temperature (manufacturer figure)[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[7]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[7]Not documented
Belts (type, width, e.g. Gates?)Rear adjustable belt tensioners with a Belt Tension Monitor[7]Automatically adjusted belt tension - the K2 and K2 Pro are tensioned by hand[2]
Stepper motors (frame size, step angle, brand if known)Not documentedStep-servo motors on the X, Y and Z axes and the extruder[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]30000 mm/s2 max acceleration (manufacturer claim) - 50% above the rest of the K2 family[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive; the service part is the "Stainless Steel Extruder Unit (P1 series)"[7]Direct drive with a 0.4 mm hardened "unicorn" quick-swap nozzle[8]
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][7]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]350 C claimed max nozzle temperature[2]
Heater cartridge power (W)Not documented100 W rated hotend power[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max build-plate temperature[1]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[1]Coated steel flex plate, heated, removable[8]
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[9][7]Smart auto levelling listed as "Available via Firmware Update" rather than shipping enabled; automatic flow-rate calibration via the nozzle AI camera[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[10]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[11][12][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)[7]4.3-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[7]Touch UI with a built-in RFID reader; Creality notes the K2 Plus has no alarm sounds, which the K2 and K2 Pro do have[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)[7]Dual-band Wi-Fi (2.4 and 5 GHz), RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[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 at 1080p 30 fps plus the nozzle AI camera[2]
Materials Support
Officially supported filament listIdeal: PLA, PETG, TPU, PVA, PET, ABS, ASA. Capable: PA, PC[1]PLA, PETG, PET, ABS, ASA, PLA-CF, PA-CF, 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[11][12]
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[13]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[14]
Independently Measured Performance
Benchmark print times (source + settings)Not documentedBenchy in 15 minutes 56 seconds - independently measured by Tom's Hardware, which noted visible layer lines and slightly droopy overhangs at that speed[8]
Review scores from major outlets (list outlet + score + date)Not documentedTom's Hardware rating 4.5 out of 5 in the page's structured data[8]

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.
