Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 2[1]ELEGOO Neptune 3 Pro[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 15 May 2023 (Shopify publish date)[1]Listed on the ELEGOO US store from 11 November 2022 (Shopify publish date)[3]
Street price (USD; dated snapshot per entry)$169.00 on store.anycubic.com, Aug 2026, against a compare-at price of $279.00 - the cheapest machine in this file[1]$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[3][4]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Base model of a five-way family that is easy to confuse. All of Kobra 2, Kobra 2 Neo and Kobra 2 Pro share the same 220 x 220 x 250 mm build volume, but their speed ceilings differ: Neo 250 mm/s max / 150 typical, Kobra 2 300 / 200, Kobra 2 Pro 500 / 300. The Plus (320 x 320 x 400 mm) and Max (420 x 420 x 500 mm) are bigger but drop the bed ceiling to 90 C where the three small ones reach 110 C. Anycubic's own note: Kobra 2 firmware must be at V3.0.6 or above for the quoted speed[1][5][6][7][8]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][9][10]
Market position: superseded? successor announced?Not documentedSuperseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[10]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 220 x 220 mm stated HWD, i.e. 220 x 220 x 250 mm in X x Y x Z; Anycubic quotes 12.1 L[1]225 x 225 x 280 mm; printing platform 235 x 235 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)486 x 440 x 435 mm stated as HWD, so the desk footprint is about 440 x 435 mm and the height is 486 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][9]
Net weight (kg)8.4 kg[1]8.1 kg net, 10.15 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame (Neptune family)[9]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame, no enclosure[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger with a gantry frame; Anycubic describes double metal spindles with SG15 bearings on the moving axes[1]Cartesian i3 bed-slinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashDouble-threaded rod Z axis (dual lead screws)[1]Two lead screws[2]
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)300 mm/s maximum print speed (Anycubic Lab figure; firmware V3.0.6 or above required)[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 speed200 mm/s recommended print speed (manufacturer figure) - the number to plan around, not the 300 mm/s headline[1]60 mm/s recommended printing speed (manufacturer figure)[2]
Max acceleration (claimed, mm/s²)3000 mm/s2 acceleration (manufacturer figure) - modest next to the 20000 mm/s2 of the current Kobra generation[1][11]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive with a dual-geared extrusion structure[1]Dual-gear direct extruder with 2 fans[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedBrass nozzle, 0.4 mm, titanium-alloy heat break[2]
Max nozzle temp claimed AND firmware max temp limit (both values)260 C nozzle temperature ceiling; 0.4 mm replaceable nozzle[1]260 C claimed max nozzle temperature - 40 C below the Neptune 4 series[2][9]
Heater cartridge power (W)60 W hotend heater (Anycubic states "upgraded extruder power reaches up to 60 watts")[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C hotbed temperature ceiling[1]100 C max heated bed temperature at 25 C ambient[2]
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)Anycubic LeviQ 2.0 automatic levelling with smart Z-offset and a user-adjustable Z compensation value[1]36-point auto-levelling (the Neptune 4 family moved to 121 points)[2][12]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted, with power-loss recovery[1]Filament run-out sensor and power-loss recovery[2]
Cooling & Air Handling

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)Not documentedMarlin - ELEGOO names the system "Marlin" for the Neptune 3 Pro, against "Klipper" for the whole Neptune 4 family[2][12]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour LCD touchscreen[1]4.3-inch colour capacitive touch screen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Not documentedColour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[2]

Calibration Routines & QoL
Assembly level & time from unbox to first printModular assembly - Anycubic states 5 pieces in about 10 minutes[1]Not documented
Materials Support
Officially supported filament listPLA, ABS, PETG, TPU[1]PLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[2][9]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating 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.
