Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[1]Sovol SV07 Plus[2][3]
Street price (USD; dated snapshot per entry)$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[1][4]$199 at 3D Printers Online Store, reduced from $379, but Out of Stock, checked Aug 2026. Sovol's own comparison quotes $259 sale / $309-379 regular[2][3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)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 Superseded by the V-Core 4.1.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[1][4]Large-format version of the SV07. Distinguishers: 300x300x350 mm vs 220x220x250, 600 W MeanWell vs 350 W, 25-point levelling, and USB Type-C added. Both are quoted at 500 mm/s and 300 °C. Note Sovol's own comparison table gives 300x300x350 while some listings write 300x300x340[3][2]
Market position: superseded? successor announced?Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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[4]Delisted by Sovol; not present in the current 3D-printer collection[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.
