| Property | Anycubic Kobra 4BEDSLINGER | 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 4[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 29 May 2026 (Shopify publish date)[4] | Not published on the listings checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | $279.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $379.00 ($320.90 for the EU plug variant)[4] | $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) | Shares its 260 mm cube volume and its exact machine dimensions (455.4 x 445.3 x 461.3 mm) with the Kobra X, so those two cannot be told apart on size. The difference is multicolour: the Kobra X ships with native 4-colour capability, while the Kobra 4 needs an ACE 2 Pro unit for multicolour and drying. The Kobra 4 also has a smaller 3.5-inch screen where the Kobra 3 and S1 use 4.3-inch panels[1][5][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| Market position: superseded?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 optional ACE 2 Pro is a separate 368 x 291.5 x 236.5 mm unit[1] | 710 x 510 x 670 mm[3] |
| Net weight (kg) | 9.9 kg for the printer (ACE 2 Pro 3.7 kg); packaged 12.6 kg bare or 17.5 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's table gives the construction as "Gantry system" - a bed-slinger, not CoreXY[1] | 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 the default[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 default 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 with 0.25, 0.6 and 0.8 mm optional[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 49-point auto-levelling with Z-offset; Anycubic claims levelling repeatability under 0.02 mm and states no manual compensation is needed[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 | Multicolour and active drying both require the separate ACE 2 Pro unit; Anycubic quotes 4 independent brushless feed motors in that unit[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; a built-in accelerometer drives vibration compensation[1] | Not documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch capacitive touchscreen - smaller than the 4.3-inch panels on the Kobra 3 and S1 series[1][6][8] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus Anycubic Slicer, the Anycubic app and USB; AI spaghetti detection and object skip supported[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB, Anycubic Slicer and the Anycubic app[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 |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Anycubic claims assembly and first print within 15 minutes[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU 95A - and Anycubic notes TPU 95A cannot be used through the ACE 2 Pro[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 in standard mode and 45 dB or less in silent print mode - manufacturer figures with no 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[9] | Not documented |
| Independently Measured Performance | ||
| Benchmark print times (source + settings) | Anycubic claims a 14-minute Benchy - a manufacturer figure with no slicer settings published, not an independent measurement[1] | 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.
