| Property | Bambu Lab X1ECOREXY | Rat Rig V-Core 4COREXY |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | Rat Rig |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab X1E; spec PDF header "Bambu Lab X1E Technical Specification"[1] | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[2] |
| Street price (USD; dated snapshot per entry) | Not documented | $2,319.99 at Fabreeko for the fully-specified US kit (price includes shipping and duty in the continental USA), Batch 4, checked Aug 2026. 300 mm ABS-parts variant in stock, 400 mm down to one unit. Rat Rig's own base kit is priced separately in EUR[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Enterprise variant of the X1-Carbon, not a trim level. Differences from the X1C, from the two manufacturer spec sheets side by side: active chamber heating to 60 C (X1C has none), 320 C vs 300 C hot end, Smooth PEI plate included vs Cool/Engineering plates, G3+H12+carbon filter stack vs carbon filter only, Ethernet with a network kill switch, removable network module and 802.1X vs Wi-Fi only, 16 kg vs 14.13 kg, and 1400 W at 220 V / 750 W at 110 V vs 1000 W / 350 W[1][4] | Three sizes (300, 400, 500 mm cubes) and three motion configurations: Standard CoreXY, Hybrid CoreXY (+$149.99, adds two motors to Y), and IDEX with two independent toolheads (+$450.00). Superseded by the V-Core 4.1. Raspberry Pi and enclosure panels are not included[2][3] |
| Market position: superseded? successor announced? | Not present in the Bambu Lab US store 3D-printer collection in Aug 2026, which lists A1, A1 mini, A2L, P1S, P2S, X2D, H2S, H2D and H2C. Bambu sells business machines through a separate Business & Institution channel, so absence from the consumer collection is not proof of discontinuation; no live first-party price could be recorded[5] | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables. Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 owners[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm (manufacturer figure)[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][3] |

| Net weight (kg) | 16 kg net (against 14.13 kg for the X1-Carbon)[1][4] | Not documented |
| Frame construction & material | Steel chassis with an aluminium and glass shell[1] | 30-series aluminium extrusion with printed ABS structural parts[2][3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a door sensor, and the only X1 with active chamber heating; the chamber is controlled to a maximum of 60 C[1] | Open by default; enclosure panels sold separately[2] |

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.
