| Property | Anycubic Kobra 4BEDSLINGER | FlashForge Guider 3 UltraINDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Anycubic | FlashForge |
| Class | BEDSLINGER | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra 4[1] | Flashforge Guider 3 Ultra; the FlashForge spec table gives the machine name as "Guider 3 Ultra"[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 29 May 2026 (Shopify publish date)[3] | Not documented |
| 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)[3] | $2,399.00 against a $3,499.00 regular price on flashforge.com, but the listing checked is the refurbished SKU and is marked Sold out (Aug 2026)[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][4][5] | Top of the Guider 3 series. Build size depends on which head is used: 330 x 330 x 600 mm with one extruder, 300 x 330 x 600 mm with both. Siblings Guider 3 (300x250x340) and Guider 3 Plus (350x350x600) are both single-extruder. A refurbished SKU exists alongside the new machine, so check which one a price refers to[2][6][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 330 x 330 x 600 mm with a single extruder; 300 x 330 x 600 mm when both extruders are in use[2] |
| 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] | 635 x 550 x 1070 mm; packaging 775 x 690 x 1235 mm[2] |
| 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] | 70 kg net, 86 kg gross[2] |
| Frame construction & material | Not documented | Enclosed professional chassis; FlashForge describes a lightweight, stable structure for high-speed operation[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Closed design with an air filter fitted[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Anycubic's table gives the construction as "Gantry system" - a bed-slinger, not CoreXY[1] | CoreXY with two extruders, per a third-party buyer's guide. FlashForge's own spec table does not state the kinematics[8][2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s the default[1] | 10-500 mm/s printing speed, 500 mm/s maximum travel speed (manufacturer figures)[2] |
| 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] | 20,000 mm/s2 maximum (manufacturer claim)[2] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Active vibration compensation, which FlashForge says was enhanced for this model. Implementation not named[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | Two extruders[2] |
| 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 maximum extruder temperature (manufacturer claim)[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm default; 0.6 and 0.8 mm optional[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C maximum hotbed temperature on a PEI spring steel build plate[1] | 120 °C bed setting supported (manufacturer figure)[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Replaceable flexible steel-plate platform, magnetic. No glass bed[2] |
| 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] | Full-auto one-click levelling; probe technology not named[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, entanglement detection and power-loss resume[1] | Filament run-out reminder[2] |
| 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 |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | Air filter fitted; filter media not specified in the FlashForge table[2] |
| Electronics & Power | ||

| Total rated power draw | Not documented | 850 W maximum[2] |
| 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 named; slicers are Orca-Flashforge and FlashPrint 5, with OrcaSlicer listed as compatible[2] |
| 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][5][9] | 7-inch touch LCD[2] |
| 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] | USB, Ethernet, Wi-Fi, plus cloud[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Standard HD camera fitted, 720p[1] | Remote camera monitoring and time-lapse video supported; resolution not published[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Anycubic claims assembly and first print within 15 minutes[1] | Not documented |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery supported; mechanism not published. Automatic shutdown also supported[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU 95A - and Anycubic notes TPU 95A cannot be used through the ACE 2 Pro[1] | PLA, ABS, HIPS, ASA, PETG, CoPA, PLA-CF, PETG-CF, PAHT-CF, PAHT-GF, PET-CF, PET-GF, PA12-CF, PA-CF, PA-GF, NexPA-CF25[2] |

| Certifications (UL/ETL/CE/FCC — verify, don't assume) | Not documented | CE, FCC, RoHS (as printed in FlashForge's own spec table)[2] |
| 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[10] | 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.
