Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra S1[1]Bambu Lab H2D[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$349.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $549.00 ($401.00 for the EU plug variant)[3]From $1,549.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $1,749.00; the product page shows $1,749.00 (typical $1,999.00) with a combo variant selected[4][5]
Variants & sibling models — and how to tell them apart (spec-contamination risk)The CoreXY line, not to be confused with the gantry/bed-slinger Kobra 3, Kobra 4 and Kobra X. Within the S line the Kobra S1 Max is a much bigger machine: 350 mm cube against 250, a 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 does not have at all, and 25.7 kg against 9.37 kg. Multicolour is sold separately on both (ACE Pro / ACE 2 Pro)[1][6]Six SKUs on one product page including H2D, H2D AMS Combo and H2D Laser Full Combo. The Laser Edition adds laser safety windows and the air-assist pump; a plain H2D can be upgraded with a Laser Upgrade Kit. The BirdsEye camera is only fitted on the Laser Edition. Siblings in the same family are the H2S (single nozzle, 340x320x340 mm, 30 kg) and H2C (dual nozzle, 305x320x325 mm single-nozzle volume, 32.5 kg, four cameras as standard) - all three share the 492x514x626 mm body, so body dimensions alone will not tell them apart[2][7][8]
Market position: superseded? successor announced?Not documentedCurrent model; the H2C sits above it in the same body at $2,199 and the H2S below it at $1,199[4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 250 x 250 mm[1]Single-nozzle printing 325 x 320 x 325 mm; dual-nozzle printing 300 x 320 x 320 mm; total volume across the two nozzles 350 x 320 x 320 mm. The sortable figure is the single-nozzle volume[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)400 x 410 x 490 mm[1]492 x 514 x 626 mm[2]
Net weight (kg)9.37 kg net, 20.2 kg packaged[1]31 kg net[2]
Frame construction & materialNot documentedAluminium, steel, plastic and glass chassis and shell[2]
Enclosure: open / enclosed; panel material; door/lidFully enclosed - Anycubic's own wording is "Fully Enclosed CoreXY Construction". There is no active chamber heating on the S1 (that is the S1 Max's addition)[1][6]Fully enclosed with a door sensor; active chamber heating to 65 C, chamber exhaust and heat-circulation fans, and a G3 + H12 HEPA + granulated coconut-shell carbon filter stack[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)CoreXY (stated outright in Anycubic's specification table)[1]CoreXY - not named in the spec sheet; Bambu groups the H2 series with its 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 recommended[1]1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[2]
Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended (manufacturer claims)[1]20000 mm/s2 max toolhead acceleration (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)Not documented40 mm3/s with the standard-flow hotend, 65 mm3/s with the optional high-flow hotend; both measured by Bambu on 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]Dual direct-drive extruders with hardened-steel gears, driven by Bambu high-precision permanent-magnet synchronous motors[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Quick-release hotend; 0.4 mm standard nozzle expandable to 0.25, 0.6 and 0.8 mm[1]All-metal hotend with hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; an optional high-flow hotend is offered[2]
Max nozzle temp claimed AND firmware max temp limit (both values)320 C maximum nozzle temperature[1]350 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C maximum hotbed temperature on a PEI spring steel build plate - the highest bed ceiling of any Anycubic machine in this file except the S1 Max[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 auto-levelling with Z-offset, plus area levelling[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, filament 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 is sold separately - the ACE Pro / ACE 2 Pro units are not included with the bare S1[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedPart-cooling fan, auxiliary part-cooling fan, chamber heat-circulation fan, hotend cooling fan, main control board fan and chamber exhaust fan, all closed-loop controlled[2]
Electronics & Power
Total rated power drawNot documented100-120 VAC / 200-240 VAC 50/60 Hz; 2200 W at 220 V, 1320 W at 110 V. The US store page states the H2D it sells is the 100-120 V version[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS, with pressure advance and flow calibration supported[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[9]
Connectivity, UI & Camera

Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Standard HD camera fitted, but only 480p - lower than the 720p units on the S1 Max, Kobra 4 and Kobra X[1][6][10]Four cameras listed: live view 1920x1080, nozzle camera 1920x1080, toolhead camera 1920x1080, and a 3264x2448 BirdsEye camera fitted only on the Laser Edition[2]
Materials Support
Officially supported filament listPLA, PETG, TPU, ABS, ASA[1]PLA, PETG, TPU, PVA, BVOH, ABS, ASA, PC, PA, PET, plus carbon/glass-fibre reinforced PLA, PETG, PA, PET, PC, ABS, ASA, PPA-CF/GF, PPS and PPS-CF/GF[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)46 dB or less in standard mode and 44 dB or less in quiet mode - manufacturer figures with no distance or method stated, so not comparable with an independently measured reading[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[11]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[12]

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.
