| Property | Rat Rig V-Core 4.1COREXY | Voron TridentCOREXY |
|---|---|---|
| Identity | ||
| 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 Trident, current revision R2. Sold as "Voron Trident R2 3D Printer Kit by LDO"[2] |
| Street price (USD; dated snapshot per entry) | Not documented | $1,274.99 for the LDO kit at Fabreeko, on pre-order with a mid-to-late September ship estimate, checked Aug 2026. Fabreeko's live product feed shows the Trident kit at $1,199.99 and unavailable, so the figure depends on which variant 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 size variants on the LDO kit: Rev D 250 mm and Rev D+ 300 mm. Distinguished from the Voron 2.4 by the Z system: Trident has a fixed gantry with three Z motors lifting the bed, while the 2.4 lifts the gantry on four belted Z motors. Colour options black, space grey, blue[2][4] |
| Market position: superseded?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] | 250 x 250 x 250 mm or 300 x 300 x 300 mm depending on variant. Sortable value is the 300 mm kit[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] | Aluminium-extrusion CoreXY frame, self-assembly[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame in the base kit[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY; Hybrid CoreXY and IDEX are configuration options[1] | CoreXY with a fixed gantry; three independent Z stepper motors raise the bed and perform bed levelling[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Three independent Z stepper motors under the bed[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | LDO Leviathan board: 5 x TMC2209 plus 2 x TMC5160 HV-capable drivers[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] | Bondtech Integrated Drive Gear Assembly (IGDA) with a Clockwork 2 motor[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | E3D Revo High Flow with a 60 W heater[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C maximum nozzle temperature (manufacturer claim)[1] | Not documented |
| Heater cartridge power (W) | Not documented | 60 W (E3D Revo High Flow heater in the LDO kit)[2] |
| 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 |
| Bed surface (material, texture, coating), single/double-sided | Not documented | LDO bed heater with a pre-installed magnet sheet and edge-to-edge heating[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Omron inductive probe supplied; Klicky-mod parts also included in the kit[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 | LDO Leviathan control board; Nitehawk SB USB toolhead board with an integrated accelerometer[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS 2.1 (Rat Rig's Klipper distribution)[1] | Klipper[2] |
| Connectivity, UI & Camera | ||
| LED chamber/toolhead lighting | Not documented | COB LED chamber lighting included[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[2] |
| 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.
