Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Markforged X7, 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 2022[1]Not documented
Launch MSRP (USD)Approximately $69,900 USD (Aniwaa quotes the same figure in EUR)[1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Top of the X series (X3, X5, X7). Markforged's other industrial lines are different machines entirely: FX10 (CA$139,986), FX20 (CA$335,860) and Metal X Gen 2 (CA$153,986). The X7 is a composite FFF machine, not a metal printer. Pricing note: No live USD listing found. CAD Micro lists the X7 (Gen 2) at CA$90,986.00, checked Aug 2026 — Canadian dollars, not USD[2][1]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Market position: superseded?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 documentedCurrent 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 usable330 x 270 x 200 mm (Aniwaa records 17.82 L)[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 483 x 914 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)48 kg[1]Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[3]
Frame construction & materialNot documented30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[3]
Enclosure: open / enclosed; panel material; door/lidEnclosed industrial 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 documentedSize-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 nameNot documentedFull-metal skeleton toolhead, new in the 4.1[3]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented350 °C maximum nozzle temperature (manufacturer claim)[3]
Stock nozzle size & sizes included in boxLayer resolution down to 0.05 mm in Z[1]0.4 mm hardened steel and 0.6 mm included[3]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented120 °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 designNot documentedImproved 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 documentedRatOS 2.1 (Rat Rig's Klipper distribution)[3]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-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 listComposites with carbon, glass and Kevlar-reinforced polymers; elastomers (TPU); thermoplastics including PLA and PA-CF. Markforged's continuous fibre strands are carbon, fibreglass or Kevlar laid inside Onyx[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.
