| Property | FlashForge Creator 4IDEX | Rat Rig V-Core 4.1COREXY |
|---|---|---|
| Identity | ||
| Brand | FlashForge | Rat Rig |
| Class | IDEX | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Flashforge Creator 4, sold in A and S configurations (Creator 4A, Creator 4S)[1] | Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[2] |
| Street price (USD; dated snapshot per entry) | $10,999.00 at Top 3D Shop with a 2-3 week lead time, checked Aug 2026[1] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Two factory configurations that share the chassis but not the temperature ceiling: Creator 4A ships 2 x HT extruders (320 °C max, no composite support), Creator 4S ships 1 x HT + 1 x HS (360 °C max, supports PA-CF, PA-GF, PP-CF, PPS-CF). A third extruder type, F, is rated 265 °C and intended for flexibles. Any published "360 °C" figure applies only to the HS head[1] | Three sizes, all at the same base-kit price. Acceleration is the size-dependent figure and the one most often mis-quoted: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm. IDEX is a configuration option and changes the usable area per toolhead (copy mode 150x150x300 at the 300 size, mirror mode 95x95x300). Base kit excludes electronics. Rat Rig prices the base kit only in EUR (EUR 873.90 on sale from EUR 971.00, Aug 2026); no USD list price is published, so no USD street price is recorded here[2] |
| Market position: superseded? successor announced? | Not documented | Current revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 400 x 350 x 500 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] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 840 x 675 x 1000 mm (1050 mm on the stand). FlashForge specifies an installation space of at least 1400 x 1500 x 1600 mm[1] | 623.2 x 583 x 785 mm (300); 723.2 x 683 x 885 mm (400); 823.2 x 783 x 985 mm (500). Sortable value is the 300 mm kit[2] |
| Net weight (kg) | 90 kg net[1] | Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[2] |
| Frame construction & material | Fully enclosed professional chassis on a stand[1] | 30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with HEPA 13 filtration and an actively controlled chamber[1] | Open frame in the base kit[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Up to 65 °C, actively controlled (manufacturer claim)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | IDEX — two independently driven extruders on the same gantry[1] | CoreXY; Hybrid CoreXY and IDEX are configuration options[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 10-200 mm/s, adjustable per material. On the 4S the HS head is quoted 100-150 mm/s and the HT head 100-200 mm/s (manufacturer figures)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | Not documented | Size-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive, two independent extruders, interchangeable modules (F / HT / HS)[1] | Full-metal skeleton toolhead, new in the 4.1[2] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Depends on the fitted extruder module: F 265 °C, HT 320 °C, HS 360 °C[1] | 350 °C maximum nozzle temperature (manufacturer claim)[2] |
| Stock nozzle size & sizes included in box | 0.4 mm default; 0.6 and 0.8 mm optional[1] | 0.4 mm hardened steel and 0.6 mm included[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 130 °C maximum (manufacturer claim)[1] | 120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic bed levelling; FlashForge does not name the probe technology in this spec table[1] | Not documented |
| Filament Handling & Detection | ||
| Spool holder location & max spool size; drybox compatibility | Two spool bays, 1 kg and 2 kg capacity[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Improved part cooling, listed by Rat Rig as one of the 4.1 changes[2] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | AC 100-130 V / 200-240 V, 50-60 Hz, 30 A overcurrent protection[1] | Not documented |
| Total rated power draw | 2320 W rated[1] | Not documented |
| Firmware & Openness | ||

| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[2] |
| Materials Support | ||
| Officially supported filament list | Standard and engineering plastics on the HT head; the HS head adds PA-CF, PA-GF, PP-CF and PPS-CF. Materials such as PC, PA and carbon fibre are the stated targets for the 130 °C bed[1] | PLA, PETG, ABS, ASA, TPU, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[2] |

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.
