| Property | Rat Rig V-Core 4COREXY | 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, sold in the US as "RatRig V-Core 4 3D Printer Kit"[1] | Roboze ARGO 350 3D Printer[2] |
| Street price (USD; dated snapshot per entry) | $2,319.99 at Fabreeko for the fully-specified US kit (price includes shipping and duty in the continental USA), Batch 4, checked Aug 2026. 300 mm ABS-parts variant in stock, 400 mm down to one unit. Rat Rig's own base kit is priced separately in EUR[1][3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Three sizes (300, 400, 500 mm cubes) and three motion configurations: Standard CoreXY, Hybrid CoreXY (+$149.99, adds two motors to Y), and IDEX with two independent toolheads (+$450.00). Superseded by the V-Core 4.1. Raspberry Pi and enclosure panels are not included[1][3] | 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][4] |
| Market position: superseded? successor announced? | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables. Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 owners[3] | 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][3] | 350 x 300 x 300 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 1130 x 1150 x 2000 mm[2] |
| Net weight (kg) | Not documented | 1200 kg[2] |
| Frame construction & material | 30-series aluminium extrusion with printed ABS structural parts[1][3] | Fully assembled, made in Italy[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open by default; enclosure panels sold separately[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, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[1] | CoreXY[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | TMC2209[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | LDO Orbiter 2.0 direct-drive extruder[1] | Single extruder, 1.75 mm filament[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Phaetus Rapido 2.0 UHF[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 450 °C maximum nozzle temperature (manufacturer specification)[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm[2] |
| Heated Bed & Surface | ||
| Bed surface (material, texture, coating), single/double-sided | Keenovo silicone bed heater[1] | Removable polymer build sheets held by vacuum[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Beacon eddy-current probe[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Nidec 4028 part-cooling fan[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | BigTreeTech Octopus[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS, Rat Rig's Klipper distribution[3] | 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; Raspberry Pi and enclosure panels sourced separately[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Not documented | 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.
