| Brand | Rat Rig | Voron Design |
| Class | COREXY | COREXY |
| 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] | Voron 0.2, current revision R1. Sold under kit vendors' names: "Voron V0.2-S1 (R1) 3D Printer Kit by LDO & HoneyBadger", "Voron 0.2 R1 Latest Version CoreXY 3D Printer Kit" (Formbot)[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | There is no single price: Voron is an open design and kits come from several vendors. Formbot's kit is $328.06 (was $349.00, 6% off), in stock, checked Aug 2026. The LDO & HoneyBadger V0.2-S1 kit is $639.99 but sold out. Neither figure includes printed parts unless the option is selected[2][3] |
| 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] | Two things get conflated. First, revision: R1 is the current one, adding a filament-runout sensor, MR85 bearings and fastener changes. Second, kit vendor: the LDO/HoneyBadger S1 kit ships an SKR Pico, E3D Revo, HoneyBadger dual-sided PEI/CF bed and 200 W supply, while the Formbot kit ships a TZ V6 or Dragon hotend and a 150 W supply, so hotend and PSU specs are vendor-specific, not model-specific. Printed parts are an extra on both[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| Market position: superseded?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] | 120 x 120 x 120 mm[2][3] |
| 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] | Aluminium-extrusion CoreXY frame with acrylic panels (LDO kit); the LDO/HoneyBadger build uses a 100 mm top hat. X axis on a genuine HIWIN rail, Y and Z on HoneyBadger stainless rails[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame in the base kit[1] | Enclosed by acrylic panels in the LDO kit[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY; Hybrid CoreXY and IDEX are configuration options[1] | CoreXY with the build plate moving in Z[2][3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Genuine HIWIN linear rail on X in the LDO kit[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 250 mm/s max print speed, 300 mm/s max travel (Formbot kit listing). This is a kit-vendor figure, not a Voron Design specification[3] |
| 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 in a Mini Stealthburner toolhead with a picobilical board and umbilical cable (LDO kit)[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Kit-dependent: E3D Revo (Voron edition) in the LDO kit; TZ V6, Dragon standard-flow or Dragon high-flow in the Formbot kit[2][3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C maximum nozzle temperature (manufacturer claim)[1] | 300 °C on the Formbot kit listing. The LDO kit's E3D Revo has its own limit, not stated on the listing[3] |
| 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] | 110 °C (Formbot kit listing)[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | HoneyBadger dual-sided P-series plate in the LDO kit: smooth black PEI on one face, carbon fibre on the other, on a Kirigami mount with an edge-to-edge polyimide film heater[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 |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Kit-dependent. LDO kit: SKR Pico (LDO Edition) with a Raspberry Pi 4B as host[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 200 W (LDO kit) or 150 W (Formbot kit)[2][3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS 2.1 (Rat Rig's Klipper distribution)[1] | Klipper[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] | Self-assembly kit. Printed parts are not included in the LDO kit (sourced separately, e.g. through Voron's Print It Forward); the Formbot kit offers them as an option[2][3] |
| 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] | 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.
