| Property | Anycubic Kobra XBEDSLINGER | ELEGOO Neptune 3 ProBEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | Anycubic | ELEGOO |
| Class | BEDSLINGER | BEDSLINGER |
| 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 3 Pro[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 11 November 2022 (Shopify publish date)[4] |
| 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][5] | $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][6] |
| 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][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| Market position: superseded?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 | Not documented | Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[9] |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 usable | 260 x 260 x 260 mm[1] | 225 x 225 x 280 mm; printing platform 235 x 235 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] | 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) | 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] | 8.1 kg net, 10.15 kg gross[2] |
| Frame construction & material | Not documented | CNC-machined aluminium extrusion frame (Neptune family)[8] |
| Enclosure: open / enclosed; panel material; door/lid | Open 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][7] | Cartesian i3 bed-slinger[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | 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) | 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 speed | 300 mm/s recommended print speed (manufacturer figure)[1] | 60 mm/s recommended printing speed (manufacturer figure)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | Dual-gear direct extruder with 2 fans[2] |
| 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, 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 limit | 100 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-sided | Not documented | PEI 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 path | Native 4-colour printing built in, expandable to 19 colours; active drying still needs a separate ACE 2 Pro[1] | Not documented |
| Electronics & Power | ||
| Total rated power draw | Not documented | 300 W rated power, 24 V output[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS with pressure advance and flow calibration supported[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? | Not documented | 4.3-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 recommended, Orca and Cura supported[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer 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] |
| 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 list | PLA, PETG, TPU, PVA, PLA-CF, PETG-CF, ASA[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) | 48 dB or less - a manufacturer figure with no mode, distance or method stated[1] | 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[11] | 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[12] |
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.
