| Property | Bambu Lab H2CCOREXY | UltiMaker Factor 4INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | UltiMaker |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab H2C; spec sheet header "H2C Spec Sheet"[1] | UltiMaker Factor 4[2] |
| Release date (announcement and actual shipping) | Not documented | Announced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[2] |
| Launch MSRP (USD) | Not documented | Starting at approximately $20,000[2] |
| Street price (USD; dated snapshot per entry) | From $2,199.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $2,399.00; the compare page shows $2,399[3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Dual-nozzle top model in the H2 family, in the same 492x514x626 mm body as the H2D and H2S. Distinguishing figures: 32.5 kg (vs 31 kg H2D, 30 kg H2S); single-nozzle volume 305x320x325 mm (vs 325x320x325 mm on the H2D); BirdsEye camera fitted as standard rather than only on a Laser Edition; laser safety window listed as equipped with the Laser Edition[1][4][5][6] | Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | Single-nozzle printing 305 x 320 x 325 mm; dual-nozzle printing 300 x 320 x 325 mm; total volume for two nozzles 330 x 320 x 325 mm. The sortable figure is the single-nozzle volume[1] | 330 x 240 x 300 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 492 x 514 x 626 mm[1] | Not documented |

| Frame construction & material | Aluminium and steel chassis with a plastic and glass outer frame[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 + granulated coconut-shell carbon filtration with VOC filtration rated Superior[1] | Enclosed with actively controlled chamber airflow and a HEPA filter[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Active chamber heating, maximum 65 C (manufacturer figure)[1] | Build volume temperature controlled up to 70 °C with actively controlled chamber airflow (manufacturer specification)[2] |
| 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] | Direct-drive dual extrusion; kinematic layout not stated in the source checked[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | Not documented |
| Max volumetric flow claimed (mm³/s) | 40 mm3/s, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual direct-drive extruders, hardened-steel gears, Bambu high-precision permanent-magnet synchronous motors[1] | Direct-drive dual extrusion[2] |
| Filament diameter | Not documented | 2.85 mm[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Hardened-steel nozzles, 0.2/0.4/0.6/0.8 mm supported; built-in filament cutter[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature[1] | 340 °C maximum with the high-temperature print core (manufacturer claim)[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Flexible steel plate with Textured PEI included; Engineering Plate also supported[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - run-out sensor and door sensor[1] | Not documented |
| Spool holder location & max spool size; drybox compatibility | Not documented | Automatic climate-controlled material handling and storage station holding humidity below 15%, storing up to six spools[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan, hotend cooling fan, chamber exhaust fan and chamber heat-circulation fan, all closed-loop controlled[1] | Not documented |
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | HEPA filter[2] |
| Electronics & Power | ||

| 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.

| 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.

| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Dimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[2] |
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.
