Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra X (store variant title "Kobra X (4 Colors)")[1]Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 25 December 2025 (Shopify publish date)[3]Not documented
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][4]$2,319.99 at Fabreeko for the fully-specified US kit (price includes shipping and duty in the continental USA), Batch 4, checked Aug 2026. 300 mm ABS-parts variant in stock, 400 mm down to one unit. Rat Rig's own base kit is priced separately in EUR[2][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][6]Three sizes (300, 400, 500 mm cubes) and three motion configurations: Standard CoreXY, Hybrid CoreXY (+$149.99, adds two motors to Y), and IDEX with two independent toolheads (+$450.00). Superseded by the V-Core 4.1. Raspberry Pi and enclosure panels are not included[2][5]
Market position: superseded? successor announced?Not documentedSuperseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables. Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 owners[5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable260 x 260 x 260 mm[1]300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[2][5]
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]Not documented
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]Not documented
Frame construction & materialNot documented30-series aluminium extrusion with printed ABS structural parts[2][5]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open by default; enclosure panels sold separately[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][6]CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTMC2209[2]
Speed & Acceleration

Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]LDO Orbiter 2.0 direct-drive extruder[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]Phaetus Rapido 2.0 UHF[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C maximum nozzle temperature[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C maximum hotbed temperature on a PEI spring steel build plate[1]Not documented
Bed surface (material, texture, coating), single/double-sidedNot documentedKeenovo silicone bed heater[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]Beacon eddy-current probe[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, entanglement detection and power-loss resume[1]Not documented
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
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedNidec 4028 part-cooling fan[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedBigTreeTech Octopus[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS with pressure advance and flow calibration supported[1]RatOS, Rat Rig's Klipper distribution[5]
Connectivity, UI & Camera
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]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app and USB drive (print only)[1]Not documented
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Standard HD camera fitted, 720p[1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit; Raspberry Pi and enclosure panels sourced separately[2]
Materials Support
Officially supported filament listPLA, PETG, TPU, PVA, PLA-CF, PETG-CF, ASA[1]Not documented
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]Not documented
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[7]Not documented

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.
