| Class | INDUSTRIAL | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Markforged Mark Two, current generation listed as Gen 2[1][2] | Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[3] |
| Release date (announcement and actual shipping) | Gen 2 dated 2024[1] | Not documented |
| Launch MSRP (USD) | From $20,000 (approximately EUR 20,000)[1] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | A no-WiFi Gen 2 variant is sold alongside the standard Gen 2 at the same list price; connectivity is therefore not implied by the model name. Sits between the Onyx Pro (fibreglass only) and the X7 (much larger, 330 x 270 x 200 mm). Pricing note: No live USD listing found. CAD Micro lists the Mark Two (Gen 2) at CA$22,386.00, and separately a Gen 2 no-WiFi variant at the same CA$22,386.00, checked Aug 2026 — Canadian dollars, not USD[2][4][5] | 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[3] |
| Market position: superseded? successor announced? | Not documented | Current revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 6.5 L (Aniwaa's figure). Exact XYZ not stated on the sources checked[1] | 300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 584 x 330 x 355 mm[1] | 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[3] |
| Net weight (kg) | 16 kg[1] | Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[3] |
| Frame construction & material | Not documented | 30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed desktop cabinet[1] | Open frame in the base kit[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Continuous fibre deposition combined with fused filament fabrication[1] | CoreXY; Hybrid CoreXY and IDEX are configuration options[3] |
| Speed & Acceleration | ||
| Max acceleration (claimed, mm/s²) | Not documented | Size-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Full-metal skeleton toolhead, new in the 4.1[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 350 °C maximum nozzle temperature (manufacturer claim)[3] |
| Stock nozzle size & sizes included in box | Layer thickness down to 0.1 mm in Z[1] | 0.4 mm hardened steel and 0.6 mm included[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Improved part cooling, listed by Rat Rig as one of the 4.1 changes[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | RatOS 2.1 (Rat Rig's Klipper distribution)[3] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[3] |
| Materials Support | ||
| Officially supported filament list | Composites with carbon, glass and Kevlar-reinforced polymers; elastomers (TPU); thermoplastics including PLA and polyamides[1] | 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[3] |
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.
