| Property | Rat Rig V-Core 4.1COREXY | Sovol SV06 PlusBEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | Rat Rig | Sovol |
| Class | COREXY | BEDSLINGER |
| 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] | Sovol SV06 Plus[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] | Larger sibling of the SV06 (220x220x250). Distinct from the SV06 Plus ACE, which is 300x300x350 mm, runs Klipper on an RK3308, adds a 4.3-inch touchscreen, camera and ceramic hotend. The 340 mm vs 350 mm Z figure is the cleanest way to tell the two apart in a spec box[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| Market position: superseded?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] | Delisted by Sovol; the current collection carries the SV06 Plus ACE instead. 3DJake shows it sold out and no longer stocked[4][2] |
| 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] | 300 x 300 x 340 mm advertised (note: the ACE version is 350 mm in Z)[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] | Not documented |
| Net weight (kg) | Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[1] | Not documented |
| Frame construction & material | 30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[1] | Open frame with linear-rail motion, supplied as an assembly kit. One 3DJake purchaser reports construction defects and linear-axis stability problems[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame in the base kit[1] | Open frame, no enclosure[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY; Hybrid CoreXY and IDEX are configuration options[1] | Cartesian i3 bedslinger[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] | Direct-drive extruder, single[2] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C maximum nozzle temperature (manufacturer claim)[1] | Not documented |
| Stock nozzle size & sizes included in box | 0.4 mm hardened steel and 0.6 mm included[1] | Not documented |
| 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 |
| 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] | Not documented |
| Connectivity, UI & Camera | ||
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Not documented | USB connection and mini-SD card[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] | 1.75 mm filament; no per-material list published on the listing[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.
