| Property | Raise3D Pro3IDEX | Rat Rig V-Core 4.1COREXY |
|---|---|---|
| Identity | ||
| Brand | Raise3D | Rat Rig |
| Class | IDEX | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Raise3D Pro3 3D Printer[1][2] | Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[3] |
| Street price (USD; dated snapshot per entry) | $2,999.00 on Raise3D's own store, available, checked Aug 2026[2] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | A crowded family with materially different prices: Pro3 $2,999, Pro3 Hyper Speed Package $4,999, Pro3 HS $4,599, Pro3 Plus HS $6,099. Build volume also changes with head count: 300 x 300 x 300 mm single-head, 255 x 300 x 300 mm dual-head. Raise3D's smaller E-series (E2 $1,999, E2CF $2,499, E3 $2,499) and the resin DF2 line are separate machines entirely[2][4][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| Market position: superseded?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 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 | 300 x 300 x 300 mm with one extruder; 255 x 300 x 300 mm with both[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) | 620 x 626 x 760 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) | 52.5 kg net[1] | Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[3] |
| Frame construction & material | Fully assembled enclosed professional chassis[1] | 30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with a HEPA and activated-charcoal filter[1] | Open frame in the base kit[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual-head with an electronic lifting system[1] | CoreXY; Hybrid CoreXY and IDEX are configuration options[3] |
| Speed & Acceleration | ||
| Max travel speed | Print-head travel speed 30-150 mm/s (manufacturer figure)[1] | Not documented |
| 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 | Dual print heads, 1.75 mm filament[1] | Full-metal skeleton toolhead, new in the 4.1[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 °C maximum nozzle temperature[1] | 350 °C maximum nozzle temperature (manufacturer claim)[3] |
| Stock nozzle size & sizes included in box | 0.4 mm default; 0.2, 0.6, 0.8 and 1.0 mm available[1] | 0.4 mm hardened steel and 0.6 mm included[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 °C maximum build-plate temperature, silicone heater[1] | 120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[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.
