| Property | Anycubic Kobra S1 MaxCOREXY | Formlabs Form 4LRESIN |
|---|---|---|
| Identity | ||
| Brand | Anycubic | Formlabs |
| Class | COREXY | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1 Max[1] | Formlabs Form 4L[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] | Not documented |
| 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][4] | Same Low Force Display engine as the Form 4 but a different machine on every physical figure: 353 x 196 x 350 mm vs 200 x 125 x 210, 46 um vs 50 um pixels, 58.5 kg vs 18.3 kg, 900 W vs 480 W, two resin cartridges vs one. Formlabs lists Basic, Premium and Complete packages, whose prices are not printer-only prices, and no printer-only USD figure was found on a live listing[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 350 x 350 x 350 mm[1] | 353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 502.7 x 483 x 584 mm[1] | 664 x 528 x 794 mm[2] |
| Net weight (kg) | 25.7 kg net, 31 kg packaged[1] | 58.5 kg[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed CoreXY with 65 C active chamber heating, dual external-circulation cooling fans and an activated carbon filter, plus a temperature and moisture display[1] | Enclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 65 C active chamber heating (manufacturer figure, actively heated rather than passive)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (stated outright in Anycubic's specification table)[1] | Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | Not documented |
| 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] | Not documented |
| 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] | Not documented |
| 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] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C maximum nozzle temperature[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C maximum hotbed temperature on a PEI spring steel build plate[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 auto-levelling[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, entanglement detection and power-loss resume[1] | Not documented |
| Multi-material/multi-color capability or official upgrade path | Up to 16-colour printing with ACE 2 Pro units, sold separately[1] | Not documented |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Activated carbon filter for odour removal; dual external-circulation cooling fans[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 9 A, 50/60 Hz, 900 W[2] |
| Total rated power draw | Not documented | 900 W[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS with pressure advance and flow calibration supported[1] | Proprietary; print preparation is PreForm[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | 7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus slicing software, Anycubic app and U-disk; AI spaghetti detection using an in-house algorithm and the 720p camera[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app and U-disk[1] | Dual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[2] |

| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Ships 95% pre-assembled; Anycubic claims unbox to print in 10 minutes[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Consumer grades: PLA, PETG, TPU (95A), TPU for ACE, PET, PLA-CF, PETG-CF, PVA. Engineering grades: ABS, ASA, PC, PA, PA6-CF, PC-CF/GF, PET-CF[1] | Formlabs resin range as for the Form 4; biocompatible materials require a B-series machine[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 48 dB or less in standard mode, as low as 45 dB in quiet 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[5] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XY dimensional tolerance +/-0.15% — a manufacturer specification[2] |
| Resin & MSLA | ||
| Masking LCD | Not documented | Low Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[2] |
| Light source | Not documented | Backlight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[2] |
| Layer height range | Not documented | 25-200 um[2] |
| Resin vat & feeding | Not documented | Two next-generation resin cartridges. No vat capacity published[2] |
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.
