| Brand | Anycubic | UltiMaker |
| Class | BEDSLINGER | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra 3 Max[1] | UltiMaker Factor 4[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 19 February 2025 (Shopify publish date)[3] | Announced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[2] |
| Launch MSRP (USD) | Not documented | Starting at approximately $20,000[2] |
| Street price (USD; dated snapshot per entry) | $429.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $699.00 ($493.00 for the EU plug variant)[3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Same 420 x 420 x 500 mm build volume as the older Kobra 2 Max, so build volume will not tell them apart - but the Kobra 3 Max is faster (600 mm/s claimed against 500), runs Kobra OS with multi-colour support and a 4.3-inch touchscreen, and is lighter at 19 kg against 21 kg. Its acceleration ceiling is 10000 mm/s2, half the 20000 mm/s2 of the smaller Kobra 3 - a difference the marketing does not lead with[1][4][5] | Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 420 x 420 x 500 mm, which Anycubic states as 88 L[1] | 330 x 240 x 300 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 706 x 640 x 753 mm[1] | Not documented |
| Net weight (kg) | 19 kg[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Enclosed with actively controlled chamber airflow and a HEPA filter[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Build volume temperature controlled up to 70 °C with actively controlled chamber airflow (manufacturer specification)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Anycubic's table gives the construction as "Gantry System" - a bed-slinger, with dual Y-axis motors added to stop layer misalignment on the large moving bed[1] | Direct-drive dual extrusion; kinematic layout not stated in the source checked[2] |
| Belts (type, width, e.g. Gates?) | Semi-automatic belt tensioning, which Anycubic pairs with motor anti-skip[1] | Not documented |
| 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) | 10000 mm/s2 maximum acceleration - half the ceiling of the smaller Kobra 3, because of the moving mass[1][5] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion") with a quick-release hotend[1] | Direct-drive dual extrusion[2] |
| Filament diameter | Not documented | 2.85 mm[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | 300 C quick-release hotend with an aerospace-grade ceramic composite throat tube; 0.4 mm standard nozzle, expandable to 0.6 and 0.8 mm[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C maximum nozzle temperature[1] | 340 °C maximum with the high-temperature print core (manufacturer claim)[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 90 C maximum hotbed temperature on a PEI spring steel plate - 20 C below the smaller Kobra 3[1][5] | Not documented |
| Heat-up time to 60°C (measured preferred) | Anycubic claims the ultra-large hotbed heats up in 125 s; no target temperature is stated for that figure and it is a manufacturer claim, not a measurement[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 auto-levelling with Z-offset and area 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 |
| Spool holder location & max spool size; drybox compatibility | Not documented | Automatic climate-controlled material handling and storage station holding humidity below 15%, storing up to six spools[2] |
| Multi-material/multi-color capability or official upgrade path | Supports 4- or 8-colour printing with ACE Pro units[1] | Not documented |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | HEPA filter[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS; Anycubic Slicer Next is built on the open-source Orca slicer[1] | Not documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus slicer, Anycubic app and USB (print only); AI spaghetti detection and object skip supported[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app and USB drive (print only)[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU (TPU is not compatible with the ACE Pro)[1] | UltiMaker-branded PPS CF, PLA, Tough PLA, Nylon, PETG, PET CF and PVA, plus validated third-party materials from BASF Forward AM, Kimya, Polymaker, LEHVOSS and Jabil[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 60 dB or less in standard mode - a manufacturer figure with no distance or method stated; markedly higher than the 46-48 dB Anycubic claims for the Kobra S1 and Kobra 4[1][6][7] | 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[8] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Dimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[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.
