| Property | Bambu Lab H2SCOREXY | FlashForge AD5XCOREXY |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | FlashForge |
| 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] | Flashforge AD5X, sold as "AD5X - Multicolor 3D Printer for High-Speed, Full-Color Printing"[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] | $399.00 sale against a $549.00 compare-at price on flashforge.com, in stock, with a further $50 off at checkout, checked Aug 2026. A refurbished AD5X is listed at $315.00[2][3] |
| 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] | Shares the 220 mm Adventurer chassis with the 5M and 5M Pro but differs on the points that matter: 300 °C nozzle (vs 280 °C), 4-colour IFS unit, NO air filtration, NO auto shutdown, and a 300 mm/s print speed against a 600 mm/s travel speed. 3DJake and eolasprints both describe it as open-frame[2][6][7][8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 340 x 320 x 340 mm (manufacturer figure)[1] | 220 x 220 x 220 mm advertised[2][6] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 492 x 514 x 626 mm - the same body as the H2D and H2C[1] | Not documented |
| Net weight (kg) | 30 kg net[1] | Not documented |
| 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] | Open frame, no enclosure and no air filtration — FlashForge's own table records "Air Filtration: No". Chamber lighting and remote monitoring are listed as expandable options rather than fitted[2][7] |
| 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[7] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | FlashForge publishes two separate figures: max travel speed 600 mm/s and max print speed 300 mm/s. The 300 mm/s print figure is the one that describes printing[2][6] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20,000 mm/s2 maximum (manufacturer claim)[2][6] |
| 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] | Direct drive, one extruder, fed by the 4-colour Intelligent Filament System (IFS)[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] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature[1] | 300 °C claimed[2][6] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm default; 0.25, 0.6 and 0.8 mm optional[2][6] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 110 °C claimed[2][6] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate and Smooth PEI plate supported[1] | PEI flexible spring-steel sheet[2][6] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic levelling; probe technology not named[2][6] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[1] | Filament detection fitted; type and location not published[2][6] |
| Multi-material/multi-color capability or official upgrade path | Not documented | Four-colour printing via the integrated Intelligent Filament System (IFS), which handles filament switching[2] |
| 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] | Not documented |
| 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] | 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[9] | Not named by FlashForge; the supported slicers are Orca-Flashforge and OrcaSlicer[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] | USB, Ethernet, Wi-Fi[2][6] |
| 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] | Not documented |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-outage recovery supported; mechanism not published[2][6] |
| 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] | PETG, PLA, TPU95A, TPU64D-75D, PLA-CF, PETG-CF[2][6] |
| 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[10] | Not documented |
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.
