ClassCOREXYCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab H2S; spec sheet header "H2S & H2S Laser Edition Spec Sheet"[1]Creality K1 (store title "Creality K1 Speedy 3D Printer")[2][3]
Street price (USD; dated snapshot per entry)From $1,199.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $1,249.00[4]$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)Single-nozzle machine sharing the H2 body. H2S and H2S Laser Edition are covered by one spec sheet: the Laser Edition adds laser safety windows, the air-assist pump and the 3264x2448 BirdsEye camera, and a plain H2S can be upgraded with a Laser Upgrade Kit. Against the dual-nozzle H2D in the same 492x514x626 mm shell: 30 kg vs 31 kg, 340x320x340 mm single-nozzle volume vs 325x320x325 mm[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]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable340 x 320 x 340 mm (manufacturer figure)[1]220 x 220 x 250 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)492 x 514 x 626 mm - the same body as the H2D and H2C[1]355 x 355 x 480 mm[2]
Net weight (kg)30 kg net[1]12.5 kg (Tom's Hardware measurement)[7]
Frame construction & materialAluminium and steel chassis and shell[1]Not documented
Enclosure: open / enclosed; panel material; door/lidFully enclosed with a door sensor; active chamber heating to 65 C, chamber exhaust and heat-circulation fans, G3 + H12 + coconut-shell carbon filtration[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]
Passive chamber temperature reached (if enclosed; measured values preferred)Active chamber heating, maximum 65 C (manufacturer figure)[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY - not named in the spec sheet; grouped by Bambu with the H2 enclosed CoreXY machines at 20000 mm/s2[1]CoreXY (Creality's own K1-series comparison table)[2]
Speed & Acceleration
Max print speed (claimed, mm/s)1000 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)20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]20000 mm/s2 max acceleration (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)40 mm3/s standard-flow hotend, 65 mm3/s optional high-flow hotend; Bambu's test is a 250 mm round single-wall model in Bambu ABS at 280 C[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive with hardened-steel gears and a Bambu high-precision permanent-magnet synchronous extruder motor; built-in filament cutter[1]Dual-gear direct-drive extruder[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)All-metal hotend, hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; optional high-flow hotend[1]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)350 C claimed max nozzle temperature[1]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]100 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate and Smooth PEI plate supported[1]Coated steel flex plate, heated, removable[7]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedAutomatic bed levelling (Tom's Hardware); unlike the K1 Max there is no lidar[7][8]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[1]Filament run-out sensor fitted[7]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart-cooling fan, hotend cooling fan, main control board fan, chamber exhaust fan, chamber heat-circulation fan and auxiliary part-cooling fan, all closed-loop controlled[1]Closed-loop part-cooling fan; PWM hotend cooling fan[2]
Electronics & Power
Total rated power draw100-120 VAC / 200-240 VAC 50/60 Hz; 2050 W at 220 V, 1170 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[9]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[10][11][2]
Connectivity, UI & Camera
Display: size, type, touch?5-inch 720x1280 touchscreen[1]4.3-inch 800x480 colour touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus mobile app and PC app[1]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-driveBuilt-in 8 GB eMMC and a USB port; touchscreen, app and PC control interfaces[1]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)Live-view camera 1920x1080 and toolhead camera 1600x1200; the 3264x2448 BirdsEye camera is fitted only on the Laser Edition[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 listPLA, PETG, TPU, PVA, BVOH, ABS, ASA, PC, PA, PET, PPS, plus carbon/glass-fibre reinforced PLA, PETG, PA, PET, PC, ABS, ASA, PPA and PPS[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[10][11]
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[12]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[7][8][13]

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.
