|---|---|---|
| Identity | ||
| Brand | QIDI | Rat Rig |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Plus5, sold as "QIDI Plus5 3D Printer"[1][2] | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[3] |
| Release date (announcement and actual shipping) | Launched 5 August 2026, 09:00 EDT / 15:00 CEST[4] | Not documented |
| Launch MSRP (USD) | $749 regular launch price; a launch-window member discount put it under $700[4] | Not documented |
| Street price (USD; dated snapshot per entry) | $749.00 for the standard model on us.qidi3d.com, checked Aug 2026. Other variants: Polar Cooler bundle $899.00, Plus5 Combo $899.00, Combo + Polar Cooler $1,049.00. No compare-at price listed[1] | $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[3][5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Four purchase variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), and Combo + Polar Cooler. The Polar Cooler is a pre-sale add-on shipping separately, so its specs are not Plus5 specs. Replaces the Plus4 (305x305x280, 450 W + 400 W chamber)[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 Superseded by the V-Core 4.1.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[3][5] |
| Market position: superseded? successor announced? | Current flagship of QIDI's large-format line as of Aug 2026; sits below the Max4 (390x390x340)[1][6] | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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[5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 320 x 320 x 300 mm advertised — QIDI states this is about 18% more volume than the Plus4[1][2][4] | 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][5] |

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.
