| Property | Rat Rig V-Core 4.1COREXY | Roboze ARGO 350INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Rat Rig | Roboze |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[1] | Roboze ARGO 350 3D Printer[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[1] | Single-extruder machine; the ARGO 500 is dual-extruder with a 500 mm cube, an 11-inch screen and 1700 kg. Both quote a 450 °C nozzle and a 180 °C chamber, so temperature figures will not tell them apart — extruder count, build size and weight will. Pricing note: Not published. Top 3D Shop lists the machine as available on backorder with a 3-5 week lead time but requires a quote request rather than showing a price, checked Aug 2026[2][3] |
| Market position: superseded? successor announced? | Current revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[1] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[1] | 350 x 300 x 300 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 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[1] | 1130 x 1150 x 2000 mm[2] |
| Net weight (kg) | Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[1] | 1200 kg[2] |
| Frame construction & material | 30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[1] | Fully assembled, made in Italy[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame in the base kit[1] | Enclosed[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 180 °C chamber temperature (manufacturer specification, actively heated)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY; Hybrid CoreXY and IDEX are configuration options[1] | CoreXY[2] |
| Speed & Acceleration | ||
| Max acceleration (claimed, mm/s²) | Size-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Full-metal skeleton toolhead, new in the 4.1[1] | Single extruder, 1.75 mm filament[2] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C maximum nozzle temperature (manufacturer claim)[1] | 450 °C maximum nozzle temperature (manufacturer specification)[2] |
| Stock nozzle size & sizes included in box | 0.4 mm hardened steel and 0.6 mm included[1] | 0.4 mm[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Removable polymer build sheets held by vacuum[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Improved part cooling, listed by Rat Rig as one of the 4.1 changes[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS 2.1 (Rat Rig's Klipper distribution)[1] | Proprietary; the recommended software is Roboze Prometheus[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 7-inch colour touchscreen[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Not documented | USB, Ethernet, Wi-Fi[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | 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[1] | PEEK, Carbon PEEK, Carbon PA, ULTEM AM9085F, PC, Functional-nylon, ABS-ESD, PP, Flex-TPU, Strong-ABS, Ultra-PLA and others[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XY accuracy 0.01 mm, Z accuracy 0.025 mm (manufacturer specification, not an independent measurement)[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.
