Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra X (store variant title "Kobra X (4 Colors)")[1]ELEGOO Neptune 4 Plus[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 25 December 2025 (Shopify publish date)[3]Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date), the same date as the Neptune 4 Max[4][5]
Street price (USD; dated snapshot per entry)$299.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $399.00 ($344.00 for the EU plug variant). The collection page headline reads "Kobra X - Price from $289"[3][6]$309.00 on us.elegoo.com, Aug 2026, against a compare-at price of $425.00. Only a Ribbon-Cable printhead variant is listed for the Plus, unlike the Neptune 4 and 4 Max which also offer a Type-C version[4][7][5]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Same 260 mm cube and the same machine dimensions as the Kobra 4 (455.4 x 445.3 x 461.3 mm) - the difference is that the Kobra X has native 4-colour printing built in, expandable to 19 colours, where the Kobra 4 needs an ACE 2 Pro for any multicolour at all. The Kobra X also takes a wider filament list (adds PVA, PLA-CF, PETG-CF, ASA) but still needs an ACE 2 Pro for active drying[1][8]Middle model of the Neptune 4 family. Against the base Neptune 4: bigger (320 x 320 x 385 mm), but a lower bed ceiling (100 C rather than 110 C) and much lower acceleration (12000 rather than 20000 mm/s2). Against the Max: smaller and lighter (14.4 kg against 18.1 kg) but with a higher bed ceiling (100 C against 85 C) and higher acceleration (12000 against 8000). Its Z drive is 2 lead screws with 2 tie rods, where the Centauri machines use 3 lead screws[2][9][10][11]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable260 x 260 x 260 mm[1]320 x 320 x 385 mm; printing platform 330 x 330 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)455.4 x 445.3 x 461.3 mm for the printer; the ACE 2 Pro, if added, is a separate 368 x 291.5 x 236.5 mm unit[1]533 x 517 x 638 mm; ELEGOO also publishes a maximum size for machine activity of 578 x 750 x 860 mm including rack and tray, so allow 750 mm of depth[2]
Net weight (kg)About 9.5 kg for the printer (Anycubic's own figure is approximate); packaged 13.2 kg bare or 18 kg as the Combo[1]14.4 kg net, 16.65 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame (Neptune 4 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)Anycubic does not state a construction type for the Kobra X, but its dimensions, price and feature set match the gantry/bed-slinger Kobra 4 rather than the CoreXY S1 series[1][8]Cartesian i3 bed-slinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedTwo lead screws with two tie rods[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documented"Silent Drive (All Axes)" is all ELEGOO publishes; the driver part number is not given on the product page[2]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]30-500 mm/s printing speed, with 250 mm/s given by ELEGOO as the recommended figure - the 500 mm/s number is a ceiling, not a working speed[2]
Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]250 mm/s recommended printing speed (manufacturer figure)[2]
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1]12000 mm/s2 maximum acceleration; default acceleration 5000 mm/s2[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Dual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[2][11]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hardened-steel nozzle, 0.4 mm standard, expandable to 0.25, 0.6 and 0.8 mm[1]Brass nozzle, 0.4 mm, with a titanium-alloy heat break[2]
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 limit100 C maximum hotbed temperature on a PEI spring steel build plate[1]100 C max heated bed temperature at 25 C ambient[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedPEI spring steel sheet; ELEGOO notes it is now upgraded to a dual-sided textured PEI + PLA-specific surface[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]Manual levelling combined with 121-point auto-levelling[2]
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; no camera, no clog detection, no auto filament unloading[2]
Multi-material/multi-color capability or official upgrade pathNative 4-colour printing built in, expandable to 19 colours; active drying still needs a separate ACE 2 Pro[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU is published[2]
Total rated power drawNot documented320 W rated power; 24 V output; 110-120 V / 220-240 V input[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS with pressure advance and flow calibration supported[1]Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 Plus, rather than the ELEGOO OS branding used on the Centauri machines)[2][11]
Connectivity, UI & Camera
Display: size, type, touch?Not documented4.3-inch colour capacitive touch screen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Control from the printer, the slicing software, the Anycubic app and USB (print only); AI spaghetti detection and object skip supported[1]Colour capacitive touch UI; ElegooSlicer is recommended, with Orca and Cura also supported[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app and USB drive (print only)[1]USB, LAN and Wi-Fi[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Standard HD camera fitted, 720p[1]Not documented
Materials Support
Officially supported filament listPLA, PETG, TPU, PVA, PLA-CF, PETG-CF, ASA[1]PLA, TPU, PETG, ABS, ASA, Nylon[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)48 dB or less - a manufacturer figure with no mode, distance or method stated[1]Operating sound is published as 65 dB or less - a manufacturer figure with no measuring distance or method given, so it is not comparable with a reviewer's dB reading[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[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.
