Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 4[1]Bambu Lab H2S; spec sheet header "H2S & H2S Laser Edition Spec Sheet"[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 29 May 2026 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$279.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $379.00 ($320.90 for the EU plug variant)[3]From $1,199.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $1,249.00[4]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Shares its 260 mm cube volume and its exact machine dimensions (455.4 x 445.3 x 461.3 mm) with the Kobra X, so those two cannot be told apart on size. The difference is multicolour: the Kobra X ships with native 4-colour capability, while the Kobra 4 needs an ACE 2 Pro unit for multicolour and drying. The Kobra 4 also has a smaller 3.5-inch screen where the Kobra 3 and S1 use 4.3-inch panels[1][5][6]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[2][7]
Physical & Frame

Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed with a door sensor; active chamber heating to 65 C, chamber exhaust and heat-circulation fans, G3 + H12 + coconut-shell carbon filtration[2]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documentedActive chamber heating, maximum 65 C (manufacturer figure)[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Anycubic's table gives the construction as "Gantry system" - a bed-slinger, not CoreXY[1]CoreXY - not named in the spec sheet; grouped by Bambu with the H2 enclosed CoreXY machines at 20000 mm/s2[2]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s the default[1]1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[2]
Recommended/typical print speed300 mm/s default print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1]20000 mm/s2 max toolhead acceleration (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)Not documented40 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[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Direct drive with hardened-steel gears and a Bambu high-precision permanent-magnet synchronous extruder motor; built-in filament cutter[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hardened-steel nozzle, 0.4 mm standard with 0.25, 0.6 and 0.8 mm optional[1]All-metal hotend, hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; optional high-flow hotend[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C maximum nozzle temperature[1]350 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C maximum hotbed temperature on a PEI spring steel build plate[1]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedTextured PEI plate and Smooth PEI plate supported[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)LeviQ 3.0 49-point auto-levelling with Z-offset; Anycubic claims levelling repeatability under 0.02 mm and states no manual compensation is needed[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, entanglement detection and power-loss resume[1]Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[2]
Multi-material/multi-color capability or official upgrade pathMulticolour and active drying both require the separate ACE 2 Pro unit; Anycubic quotes 4 independent brushless feed motors in that unit[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedPart-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[2]
Electronics & Power
Total rated power drawNot documented100-120 VAC / 200-240 VAC 50/60 Hz; 2050 W at 220 V, 1170 W at 110 V[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS with pressure advance and flow calibration; a built-in accelerometer drives vibration compensation[1]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[8]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch capacitive touchscreen - smaller than the 4.3-inch panels on the Kobra 3 and S1 series[1][6][9]5-inch 720x1280 touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus Anycubic Slicer, the Anycubic app and USB; AI spaghetti detection and object skip supported[1]Touchscreen plus mobile app and PC app[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB, Anycubic Slicer and the Anycubic app[1]Built-in 8 GB eMMC and a USB port; touchscreen, app and PC control interfaces[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Standard HD camera fitted, 720p[1]Live-view camera 1920x1080 and toolhead camera 1600x1200; the 3264x2448 BirdsEye camera is fitted only on the Laser Edition[2]
Calibration Routines & QoL
Assembly level & time from unbox to first printAnycubic claims assembly and first print within 15 minutes[1]Not documented
Materials Support
Officially supported filament listPLA, PETG, TPU 95A - and Anycubic notes TPU 95A cannot be used through the ACE 2 Pro[1]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[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)48 dB or less in standard mode and 45 dB or less in silent print mode - manufacturer figures with no distance or method stated[1]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[10]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[11]
Independently Measured Performance
Benchmark print times (source + settings)Anycubic claims a 14-minute Benchy - a manufacturer figure with no slicer settings published, not an independent measurement[1]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.
