| Property | Anycubic Kobra S1COREXY | FlashForge Guider 3 UltraINDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Anycubic | FlashForge |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1[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 2 January 2025 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $349.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $549.00 ($401.00 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) | The CoreXY line, not to be confused with the gantry/bed-slinger Kobra 3, Kobra 4 and Kobra X. Within the S line the Kobra S1 Max is a much bigger machine: 350 mm cube against 250, a 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 does not have at all, and 25.7 kg against 9.37 kg. Multicolour is sold separately on both (ACE Pro / ACE 2 Pro)[1][4] | 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][5][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 250 x 250 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) | 400 x 410 x 490 mm[1] | 635 x 550 x 1070 mm; packaging 775 x 690 x 1235 mm[2] |
| Net weight (kg) | 9.37 kg net, 20.2 kg packaged[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 | Fully enclosed - Anycubic's own wording is "Fully Enclosed CoreXY Construction". There is no active chamber heating on the S1 (that is the S1 Max's addition)[1][4] | Closed design with an air filter fitted[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (stated outright in Anycubic's specification table)[1] | CoreXY with two extruders, per a third-party buyer's guide. FlashForge's own spec table does not state the kinematics[7][2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | 10-500 mm/s printing speed, 500 mm/s maximum travel speed (manufacturer figures)[2] |
| 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 (manufacturer claims)[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?) | Quick-release hotend; 0.4 mm standard nozzle expandable to 0.25, 0.6 and 0.8 mm[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 320 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 | 120 C maximum hotbed temperature on a PEI spring steel build plate - the highest bed ceiling of any Anycubic machine in this file except the S1 Max[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 auto-levelling with Z-offset, plus area levelling[1] | Full-auto one-click levelling; probe technology not named[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, filament entanglement detection and power-loss resume[1] | Filament run-out reminder[2] |
| Multi-material/multi-color capability or official upgrade path | Multicolour is sold separately - the ACE Pro / ACE 2 Pro units are not included with the bare S1[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 | ||
| Input voltage (110/220 V, switch or auto) | Not documented | AC 100-240 V, 50/60 Hz[2] |
| 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 supported[1] | Not named; slicers are Orca-Flashforge and FlashPrint 5, with OrcaSlicer listed as compatible[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | 7-inch touch LCD[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus 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, USB (print only)[1] | USB, Ethernet, Wi-Fi, plus cloud[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Standard HD camera fitted, but only 480p - lower than the 720p units on the S1 Max, Kobra 4 and Kobra X[1][4][8] | Remote camera monitoring and time-lapse video supported; resolution not published[2] |
| 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, ABS, ASA[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] |
| Safety | ||
| 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) | 46 dB or less in standard mode and 44 dB or less in quiet mode - manufacturer figures with no distance or method stated, so not comparable with an independently measured reading[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 |
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.
