Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 3 Max[1]ELEGOO Neptune 4 Max[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 19 February 2025 (Shopify publish date)[3]Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date)[4]
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]$389.00 on us.elegoo.com, Aug 2026, against a compare-at price of $559.99; Ribbon-Cable and Type-C printhead variants are the same price[4]
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][5][6]Largest Neptune 4. The trade-off against the smaller models is easy to miss: the bed only reaches 85 C (against 100 C on the Plus and 110 C on the base Neptune 4) and acceleration is capped at 8000 mm/s2 (against 12000 and 20000), because of the mass of a 430 x 430 mm moving bed. Two printhead variants, Ribbon-Cable and Type-C, are sold under one SKU[2][7][8][4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable420 x 420 x 500 mm, which Anycubic states as 88 L[1]420 x 420 x 480 mm; printing platform 430 x 430 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)706 x 640 x 753 mm[1]658 x 632 x 740 mm; ELEGOO's maximum size for machine activity is 658 x 950 x 960 mm including rack and tray - allow nearly a metre of depth and height[2]
Net weight (kg)19 kg[1]18.1 kg net, 21.8 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame, no enclosure[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]Cartesian i3 bed-slinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedTwo lead screws with two tie rods[9]
Belts (type, width, e.g. Gates?)Semi-automatic belt tensioning, which Anycubic pairs with motor anti-skip[1]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documented"Silent Drive (All Axes)"; no driver part number published[9]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]500 mm/s max toolhead speed (manufacturer claim)[2]
Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[9]
Max acceleration (claimed, mm/s²)10000 mm/s2 maximum acceleration - half the ceiling of the smaller Kobra 3, because of the moving mass[1][6]8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion") with a quick-release hotend[1]Dual-gear direct extruder with 2 fans[9]
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]Brass nozzle, 0.4 mm, with a titanium-alloy heat break[9]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C maximum nozzle temperature[1]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit90 C maximum hotbed temperature on a PEI spring steel plate - 20 C below the smaller Kobra 3[1][6]85 C max heated bed temperature at 25 C ambient - well below the 100-110 C of the smaller Neptunes, which limits ABS/ASA work despite them being on the compatibility list[2]
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
Bed surface (material, texture, coating), single/double-sidedNot documentedPEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[9]
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]Manual levelling combined with 121-point auto-levelling[9]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, entanglement detection and power-loss resume[1]Filament detection and power-loss resume printing[2]
Multi-material/multi-color capability or official upgrade pathSupports 4- or 8-colour printing with ACE Pro units[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documented"Klipper High-Speed Quiet Motherboard" is all ELEGOO publishes[9]
Input voltage (110/220 V, switch or auto)Not documented100-120 V / 220-240 V, 50/60 Hz[2][9]
Total rated power drawNot documented320 W rated power, 24 V output[9]
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]Klipper[9]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch capacitive touchscreen[1]4.3-inch colour capacitive touch screen[9]
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]Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[9]
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app and USB drive (print only)[1]Wi-Fi, USB and WLAN file transfer[2]
Materials Support
Officially supported filament listPLA, PETG, TPU (TPU is not compatible with the ACE Pro)[1]PLA, TPU, PETG, ABS, ASA, Nylon - but note the 85 C bed ceiling against ABS and ASA[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][10][11]Operating sound published as 65 dB or less - a manufacturer figure with no distance or method stated[9]
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[12]12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[13]

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.
