|---|---|---|
| Identity | ||
| Brand | Bambu Lab | Creality |
| Class | COREXY | COREXY |
| 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 Max[2] |
| 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[3] | $549.00 on store.creality.com, Aug 2026. Creality's comparison page shows $799 against a struck-through $899 on the same day[4][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] | The large K1. Build volume 300 x 300 x 300 mm and footprint 435 x 462 x 526 mm, both much larger than the K1/K1C's 220 mm cube and 355 mm-wide body; rated power is 1000 W against 350 W; it is the only K1 with RJ45 Ethernet. Its hotend is the older metal + PTFE-tube type with a copper nozzle, annotated by Creality as "Changing to All-metal Soon" and "Copper Nozzle Changing to Steel-tipped Nozzle Integrated with Heatbreak Soon", so hotend type varies by production run - do not assume it matches the K1C[2][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 340 x 320 x 340 mm (manufacturer figure)[1] | 300 x 300 x 300 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] | 435 x 462 x 526 mm[2] |
| Net weight (kg) | 30 kg net[1] | 18 kg (Tom's Hardware measurement)[7] |
| Frame construction & material | Aluminium and steel chassis and shell[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Fully 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 speed | Not documented | 300 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 name | Direct 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 tube and a copper nozzle, both annotated by Creality as changing to all-metal and to a steel-tipped integrated nozzle "soon"[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 limit | 120 C max heatbed temperature[1] | 100 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate and Smooth PEI plate supported[1] | Smooth PEI steel flex plate, heated[7] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic bed levelling assisted by a lidar sensor - Tom's Hardware records "Automatic + LIDAR", a feature the K1 and K1C do not have[7][8][9] |
| 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 design | Part-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 and PWM hotend fan, both annotated as changing to dynamically balanced versions; activated-carbon air filter fitted[2] |
| Electronics & Power | ||
| Total rated power draw | 100-120 VAC / 200-240 VAC 50/60 Hz; 2050 W at 220 V, 1170 W at 110 V[1] | 1000 W rated power - nearly three times the K1/K1C figure[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[10] | Creality OS, a Klipper derivative published as CrealityOfficial/K1_Series_Klipper on GitHub (GPL-3.0); the printhead front cover is listed as an open-source part[11][12][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 with remote monitoring, time-lapse, build-surface detection and failure detection all included[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Built-in 8 GB eMMC and a USB port; touchscreen, app and PC control interfaces[1] | Wi-Fi plus RJ45 Ethernet - the only K1-series machine with a wired network port; 8 GB 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] | 1080p AI camera fitted as standard with foreign-object detection[2] |
| Materials Support | ||
| Officially supported filament list | PLA, 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] | ABS, PLA, PETG, PET, TPU, PA, ASA, PC, PLA-CF, PA-CF, PET-CF[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Not 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[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 | ||
| Review scores from major outlets (list outlet + score + date) | Not documented | Tom's Hardware rating 4.5 out of 5 in the page's structured data[7] |
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.
