| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Raise3D Pro3 3D Printer[1][2] | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[3] |
| Street price (USD; dated snapshot per entry) | $2,999.00 on Raise3D's own store, available, checked Aug 2026[2] | $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][4] |
| 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][5][1] | 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 Superseded by the V-Core 4.1.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][4] |
| Market position: superseded? successor announced? | Not documented | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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] |
| 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][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 620 x 626 x 760 mm[1] | 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.
