| Property | Anycubic Kobra XBEDSLINGER | QIDI i-FastIDEX |
|---|---|---|
| Identity | ||
| Brand | Anycubic | QIDI |
| Class | BEDSLINGER | IDEX |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra X (store variant title "Kobra X (4 Colors)")[1] | QIDI Tech i-Fast, also written iFast and "I-Fast"[2][3] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 25 December 2025 (Shopify publish date)[4] | Not published on the listings checked (Aug 2026)[2][3] |
| 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"[4][5] | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[3][2] |
| 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] | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[3][2] |
| Market position: superseded? successor announced? | Not documented | Discontinued; QIDI's current line is the Q, Plus and Max series[3][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 330 x 250 x 320 mm advertised[2][3] |
| 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] | 710 x 510 x 670 mm[3] |
| 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] | 33 kg net[3] |
| Frame construction & material | Not documented | Fully assembled enclosed metal-frame machine[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Fully enclosed with a heated chamber[2][3] |
| 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] | Dual independent extruders in an enclosed Cartesian gantry[2][3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[3] |
| Recommended/typical print speed | 300 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 name | Direct drive ("short distance extrusion")[1] | Direct-drive, two extruders. MK10-style nozzle[2][3] |
| 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] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C maximum nozzle temperature[1] | 350 °C on the high-temperature extruder assembly[2][3] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm nozzle diameter[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C maximum hotbed temperature on a PEI spring steel build plate[1] | Not documented |
| 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] | Not documented |
| 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 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 | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 110-220 V[3] |
| Total rated power draw | Not documented | 700 W rated[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS with pressure advance and flow calibration supported[1] | Not documented |
| 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-drive | Printer UI, slicing software, Anycubic app and USB drive (print only)[1] | Wi-Fi, LAN, USB flash drive[2][3] |
| 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] | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[3] |
| 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[8] | 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.
