ClassCOREXYCOREXY
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 K1 (store title "Creality K1 Speedy 3D Printer")[2][3]
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[4][1]$299.00 on store.creality.com, Aug 2026. Creality's own K1-series comparison page shows $389 against a struck-through $599 on the same day[3][2]
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]Base model of the K1 family. The differences that matter are in the hotend: the K1 uses a metal + PTFE-tube hotend with a copper nozzle, while the K1C is all-metal with a steel-tipped nozzle integrated with the heatbreak and adds an air filter and a 1080p AI camera. Creality's own comparison table annotates the K1 hotend "Changing to All-metal Soon", so the hotend on a given unit depends on when it was built - check before buying. The K1 Max is the 300 mm version with 1000 W rated power and Ethernet; the K1 SE has a PA+30%GF hotend and an epoxy plate[2][6]
Market position: superseded?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[4][7]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]220 x 220 x 250 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 458 mm; package 485 x 480 x 530 mm[1]355 x 355 x 480 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]12.5 kg (Tom's Hardware measurement)[8]
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 passive chamber heating only - Creality's comparison table lists "Passive Heating" for the K1, K1C and K1 Max and no chamber heating for the K1 SE[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[9]CoreXY (Creality's own K1-series comparison table)[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[9]Not documented
Belts (type, width, e.g. Gates?)Rear adjustable belt tensioners with a Belt Tension Monitor[9]Not documented
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). Creality's own footnote says the 600 mm/s figure was achieved in Creality Lab and that the typical speed is 300 mm/s[2][6]
Recommended/typical print speedNot documented300 mm/s typical printing speed with 12000 mm/s2 typical acceleration, stated by Creality alongside the 600 mm/s headline[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)"[9]Dual-gear direct-drive extruder[2]
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][9]Metal hotend with a PTFE (Teflon) tube in the filament path and a copper nozzle. Creality's own comparison table adds "(Changing to All-metal Soon)", so this is a moving target across production runs[2]
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]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max build-plate temperature[1]100 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[10][9]Automatic bed levelling (Tom's Hardware); unlike the K1 Max there is no lidar[8][11]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - filament run-out sensor[1]Filament run-out sensor fitted[8]
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]Closed-loop part-cooling fan; PWM hotend cooling fan[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]350 W rated power[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[12]Creality OS, a Klipper derivative. Creality publishes the source as CrealityOfficial/K1_Series_Klipper on GitHub, whose own description is "clone from https://github.com/Klipper3d/klipper/", GPL-3.0, last pushed December 2025[13][14][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)[9]4.3-inch 800x480 colour 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[9]Colour touch UI; remote monitoring, time-lapse, failure detection and build-surface detection are all optional on the K1 because they depend on the optional AI camera[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)[9]Wi-Fi only - no Ethernet (the K1 Max adds RJ45); 8 GB of on-board 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]AI camera optional, not fitted as standard - unlike the K1C and K1 Max, which include a 1080p camera[2]
Materials Support
Officially supported filament listIdeal: PLA, PETG, TPU, PVA, PET, ABS, ASA. Capable: PA, PC[1]Hyper PLA, PLA, PETG, TPU, ABS - a notably shorter list than the K1C, because of the PTFE-lined hotend[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedNot verified directly. Creality's published firmware for the K1 series (CrealityOfficial/K1_Series_Klipper, GPL-3.0) is described by Creality itself as a clone of upstream Klipper, and upstream Klipper ships the verify_heater thermal-runaway check; whether Creality's stock printer.cfg enables it, and with what thresholds, was not checked here[13][14]
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[15]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[3]
Independently Measured Performance
Review scores from major outlets (list outlet + score + date)Not documentedTom's Hardware rating 4 out of 5 in the page's structured data - the lowest of the K1 family, where the K1C and K1 Max both score 4.5[8][11][16]

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.
