| Property | Anycubic Kobra S1 MaxCOREXY | Bambu Lab H2DCOREXY |
|---|---|---|
| Identity | ||
| Brand | Anycubic | Bambu Lab |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1 Max[1] | Bambu Lab H2D[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 16 January 2026 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $699.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $899.00 ($804.00 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 large enclosed Anycubic. Against the Kobra S1: 350 mm cube against 250 (Anycubic claims 174% more volume), 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 lacks entirely, a titanium-alloy throat tube and hardened-steel extruder gears, an activated carbon filter, 720p camera against 480p, and 25.7 kg against 9.37 kg. Its engineering-filament list is correspondingly longer[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| Market position: superseded?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 documented | Current model; the H2C sits above it in the same body at $2,199 and the H2S below it at $1,199[4] |

| Build volume X×Y×Z (mm) — advertised vs actually usable | 350 x 350 x 350 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) | 502.7 x 483 x 584 mm[1] | 492 x 514 x 626 mm[2] |
| Net weight (kg) | 25.7 kg net, 31 kg packaged[1] | 31 kg net[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 speed | 300 mm/s recommended 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 documented | 40 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 name | Direct drive ("short distance extrusion") with hardened-steel extruder gears, which Anycubic rates at six times the life of brass on carbon-fibre filament[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 with a titanium-alloy throat tube; 0.4 mm and 0.6 mm nozzles supplied, 0.25 and 0.8 mm optional; hardened steel[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] |

| 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] |
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.
