Bambu Lab H2S vs Markforged Onyx One — documented properties and sources
PropertyBambu Lab H2SCOREXYMarkforged Onyx OneINDUSTRIAL
Identity
BrandBambu LabMarkforged
ClassCOREXYINDUSTRIAL
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]Markforged Onyx One Desktop 3D Printer[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]Not documented
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][4]The defining limitation: the Onyx One prints Onyx only and has NO continuous-fibre reinforcement. The Onyx Pro adds fibreglass, the Mark Two adds the full continuous-fibre range, and the X7 is a much larger industrial machine. Onyx One specifications must never be read from Mark Two or X-series material lists[2][5][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable340 x 320 x 340 mm (manufacturer figure)[1]12.6 x 5.2 x 6.1 in (approximately 320 x 132 x 155 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]Not documented
Net weight (kg)30 kg net[1]Not documented
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 desktop cabinet[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]Not documented
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 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]Single extruder — plastic only, no fibre channel[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]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]Not documented
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate and Smooth PEI plate supported[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[1]Not documented
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]Not documented
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]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[7]Proprietary; slicing and print management run in Markforged's cloud-based Eiger software[2]
Connectivity, UI & Camera
Display: size, type, touch?5-inch 720x1280 touchscreen[1]Not documented
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus mobile app and PC app[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveBuilt-in 8 GB eMMC and a USB port; touchscreen, app and PC control interfaces[1]Not documented
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
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]Onyx only — Markforged's nylon filled with chopped carbon fibre. Markforged claims parts 1.4x stronger than ABS and heat deflection to 293 °F (145 °C)[2]
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[8]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.
