| Property | Bambu Lab X2DCOREXY | Rat Rig V-Core 4.1COREXY |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | Rat Rig |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab X2D; spec PDF header "X2D Spec"[1] | Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[2] |
| Street price (USD; dated snapshot per entry) | From $649.00 on the Bambu Lab US store, Aug 2026; the compare page shows the same $649 figure[3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Dual-nozzle machine: a main hotend with a permanent-magnet synchronous extruder motor and an auxiliary hotend with a plain stepper motor, so the two nozzles are not equivalent. Bambu publishes four different build volumes depending on which nozzle is used, and a shorter list of materials for the auxiliary nozzle. Physical dimensions (392x406x478 mm) are shared with the P2S but the X2D is 16.25 kg against the P2S's 14.9 kg[1][4] | 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[2] |
| Market position: superseded? successor announced? | Current model, launched into the slot vacated by the discontinued X1-Carbon[3] | Current revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | Main nozzle 256 x 256 x 260 mm; auxiliary nozzle 235.5 x 256 x 256 mm; dual-nozzle printing 235.5 x 256 x 256 mm; total volume for two nozzles 256 x 256 x 260 mm. The sortable figure below is the main-nozzle volume[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[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 392 x 406 x 478 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[2] |
| Net weight (kg) | 16.25 kg net[1] | Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[2] |
| Frame construction & material | Plastic and steel chassis; plastic, glass and metal outer frame[1] | 30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a door sensor, active chamber heating to 65 C, and a G3 + H12 HEPA + granulated coconut-shell carbon filter stack with an external exhaust fan[1] | Open frame in the base kit[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Active chamber heating, maximum 65 C (manufacturer figure)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - not stated in the spec sheet; Bambu groups the X2D with its enclosed CoreXY machines and publishes the same 20000 mm/s2 acceleration figure[1] | CoreXY; Hybrid CoreXY and IDEX are configuration options[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | Size-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[2] |
| Max volumetric flow claimed (mm³/s) | 40 mm3/s, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Two direct-drive extruders: main extruder with hardened-steel gears driven by a Bambu high-precision permanent-magnet synchronous motor, auxiliary extruder with hardened-steel gears driven by a stepper motor[1] | Full-metal skeleton toolhead, new in the 4.1[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Dual hardened-steel nozzles; 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; built-in filament cutter[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 350 °C maximum nozzle temperature (manufacturer claim)[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm hardened steel and 0.6 mm included[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[2] |
| Bed surface (material, texture, coating), single/double-sided | Flexible steel plate, Textured PEI included; Smooth PEI, Cool Plate SuperTack and Engineering Plate supported[1] | Not documented |

| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[7] | 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.
