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]VzBoT AWD 330, also written Vz330. Sold as "DIY VzBoT AWD 330 VZ330 3D Printer Kit" by Mellow[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]$1,360.00 at Mellow, available and shipping from China, checked Aug 2026[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][4]Ordered by colour (black or silver) and mains voltage (110 V or 220 V). Mellow describes the kit as a test version that still requires the buyer to print some components, and the 5-inch DSI screen requires a host computer that supports DSI — neither is included[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable340 x 320 x 340 mm (manufacturer figure)[1]330 x 330 x 400 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]530 x 500 x 720 mm body dimensions[2]
Net weight (kg)30 kg net[1]31 kg net, 36 kg gross[2]
Frame construction & materialAluminium and steel chassis and shell[1]CNC-machined all-metal frame with carbon-rod components[2]
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]Not documented
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 in an AWD (all-wheel drive) arrangement — two motors on X and two on Y, four in total for the XY plane, each on its own external driver[2]
X-axis guide type (rods / linear rails / V-wheels; size)Not documentedLDO 9 mm rail on X; LDO 12 mm dual rails on Y; 10 mm optical shafts on Z[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedFour external TMC5160 drivers for the LDO XY motors[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 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]Lightweight all-metal direct drive with a twill drive wheel[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]VZ High Speed hotend[2]
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]120 °C maximum bed temperature (manufacturer claim)[2]
Bed heater type (DC/AC mains) & wattageNot documented750 W silicone bed heater on an 8 mm aluminium plate[2]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate and Smooth PEI plate supported[1]8 mm aluminium plate with a magnetic spring-steel PEI-coated sheet[2]
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
Mainboard model & MCU (exact chip markings if teardowns exist)Not documented32-bit mainboard, quoted by Mellow at 550 Hz. Exact board model not named on the listing[2]
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[5]Klipper or RepRapFirmware[2]
Connectivity, UI & Camera
Display: size, type, touch?5-inch 720x1280 touchscreen[1]5-inch DSI display; requires a compatible host computer, which is not included[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]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
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit; some parts must be printed by the buyer[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]Not documented
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[6]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.
