Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 3 Max[1]ELEGOO Neptune 3 Pro[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 11 November 2022 (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]$259.99 on us.elegoo.com, Aug 2026, with the compare-at price also $259.99 - notably more than the newer and far faster Neptune 4 at $219[4][5]
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][6][7]The last Neptune 3 still listed; the 3 Plus and 3 Max are gone from the store's Neptune section. Do not read Neptune 4 figures onto it: the 3 Pro runs Marlin, not Klipper, tops out at 180 mm/s rather than 500, uses a 36-point mesh rather than 121-point, and its nozzle stops at 260 C rather than 300 C. Its machine size, 475 x 445 x 515 mm, is identical to the Neptune 4's, so body dimensions will not tell them apart[2][8][9]
Market position: superseded? successor announced?Not documentedSuperseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[9]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable420 x 420 x 500 mm, which Anycubic states as 88 L[1]225 x 225 x 280 mm; printing platform 235 x 235 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)706 x 640 x 753 mm[1]475 x 445 x 515 mm - the same body as the Neptune 4. ELEGOO's maximum size for machine activity is 475 x 580 x 725 mm[2][8]
Net weight (kg)19 kg[1]8.1 kg net, 10.15 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame (Neptune family)[8]
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[2]
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[2]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]30-180 mm/s, with 60 mm/s given by ELEGOO as the recommended speed - a pre-Klipper machine, and the slowest in this file apart from the OrangeStorm Giga[2]
Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]60 mm/s recommended printing speed (manufacturer figure)[2]
Max acceleration (claimed, mm/s²)10000 mm/s2 maximum acceleration - half the ceiling of the smaller Kobra 3, because of the moving mass[1][7]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion") with a quick-release hotend[1]Dual-gear direct extruder with 2 fans[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]Brass nozzle, 0.4 mm, titanium-alloy heat break[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C maximum nozzle temperature[1]260 C claimed max nozzle temperature - 40 C below the Neptune 4 series[2][8]
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][7]100 C max heated bed temperature at 25 C ambient[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[2]
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]36-point auto-levelling (the Neptune 4 family moved to 121 points)[2][10]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, entanglement detection and power-loss resume[1]Filament run-out sensor and power-loss recovery[2]
Multi-material/multi-color capability or official upgrade pathSupports 4- or 8-colour printing with ACE Pro units[1]Not documented
Electronics & Power
Total rated power drawNot documented300 W rated power, 24 V output[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]Marlin - ELEGOO names the system "Marlin" for the Neptune 3 Pro, against "Klipper" for the whole Neptune 4 family[2][10]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch capacitive touchscreen[1]4.3-inch colour capacitive touch screen[2]
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[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app and USB drive (print only)[1]TF (microSD) card and USB cable only - no LAN and no Wi-Fi[2]
Materials Support
Officially supported filament listPLA, PETG, TPU (TPU is not compatible with the ACE Pro)[1]PLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[2][8]
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][11][12]Operating sound published as 48 dB or less - a manufacturer figure with no distance or method stated[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[13]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[14]

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.
