Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 3 Combo - the Kobra 3 sold together with the ACE Pro filament unit[1]ELEGOO Neptune 4 Plus[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 30 April 2024 (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)$329.00 with a US plug on store.anycubic.com, Aug 2026 ($355.00 for the EU plug variant)[3]$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][6][5]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Two things to watch here. First, the Combo is printer plus ACE Pro; the ACE Pro alone weighs 4.6 kg and measures 366 x 283 x 235 mm, so plan bench space for both. Second, Anycubic's own specification table on this page mixes generations - the weight row reads "Kobra 3 V2 - 9.2kg" while the package row reads "Kobra 3 - 12kg", and a separate Kobra 3 V2 Combo product is listed at the same price. Treat any single figure from this page as needing confirmation against the exact SKU[1][3][7]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][8][9][10]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 250 x 260 mm; Anycubic quotes a 16.25 L maximum printing volume[1]320 x 320 x 385 mm; printing platform 330 x 330 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)452.9 x 504.7 x 483 mm for the printer; the ACE Pro is a separate 365.94 x 282.84 x 234.5 mm box[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)Anycubic's table gives "Kobra 3 V2 - 9.2kg" for the machine weight and "Kobra 3 - 12kg" for the package weight, plus 4.6 kg for the ACE Pro - the two rows do not refer to the same thing, so treat 9.2 kg as the machine and 12 kg as shipping weight[1]14.4 kg net, 16.65 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame (Neptune 4 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 specification table gives the construction as "Gantry System" - it is a bed-slinger, not the CoreXY layout used by the Kobra S1 series[1][11]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), with 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 (manufacturer claims)[1]12000 mm/s2 maximum acceleration; default acceleration 5000 mm/s2[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive (Anycubic's term is "short distance extrusion")[1]Dual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[2][10]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)300 C quick-release hotend; 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[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C maximum nozzle temperature (manufacturer figure)[1]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 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, plus 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, filament entanglement detection, nozzle clog 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 path4-colour printing with one ACE Pro, or up to 8 colours with two units[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. Anycubic's slicer, Anycubic Slicer Next, is stated to be built on the open-source Orca slicer[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][10]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch capacitive touchscreen with a 30-60 degree adjustable tilt[1]4.3-inch colour capacitive touch screen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus Anycubic Slicer Next, the Anycubic app and USB (print only); AI spaghetti detection and object skip are 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)Camera is optional on the Kobra 3 - a 720p HD unit, not fitted as standard, unlike the Kobra S1, Kobra 4 and Kobra X[1][11][12]Not documented
Materials Support
Officially supported filament listPLA, PETG and TPU, and Anycubic notes TPU is not compatible with the ACE Pro multi-material unit[1]PLA, TPU, PETG, ABS, ASA, Nylon[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating 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[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.
