| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Phrozen Sonic Mighty Revo 14K 10.1" LCD 3D Printer[1][2][3] | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[4] |
| Street price (USD; dated snapshot per entry) | $680.00 on us.phrozen3d.com but unavailable — backordered, shipping when back in stock, checked Aug 2026. 3DJake also shows it sold out and delisted[3][2][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[4][5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The Sonic Mighty family spans several resolutions at the same 10.1-inch size and very different prices: Mighty 4K $149, Mighty 8K $410, Mighty 12K $329, Mighty Revo 14K $680, Mighty 16K $720. A "Sonic Mighty" spec box is meaningless without the resolution suffix. Sources also disagree on this model's own numbers: Phrozen gives machine dimensions 353 x 345 x 517 mm and XY 16.8 x 24.8 um, while 3DJake gives 228 x 337 x 516 mm and XY 16.8 x 24 um. Phrozen's own figures are used here. 8 GB onboard storage[2][1][3] | 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 Superseded by the V-Core 4.1.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[4][5] |
| Market position: superseded?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 | Not documented | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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[5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 223 x 126 x 235 mm[1][3] | 300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[4][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 353 x 345 x 517 mm per Phrozen. 3DJake publishes 228 x 337 x 516 mm, which cannot be right for a machine with a 223 mm-wide build area[3][1] | Not documented |
| Net weight (kg) | 18 kg[3] | Not documented |
| Frame construction & material | Not documented | 30-series aluminium extrusion with printed ABS structural parts[4][5] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a UV-blocking cover[1] | Open by default; enclosure panels sold separately[4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | MSLA, single Z axis on dual linear guide rails with a ball screw, straight-lift peel[1][3] | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[4] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Dual linear guide rails with a ball screw[1][3] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | TMC2209[4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | LDO Orbiter 2.0 direct-drive extruder[4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Phaetus Rapido 2.0 UHF[4] |
| Heated Bed & Surface | ||
| Bed surface (material, texture, coating), single/double-sided | Not documented | Keenovo silicone bed heater[4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling[1] | Beacon eddy-current probe[4] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Nidec 4028 part-cooling fan[4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | BigTreeTech Octopus[4] |
| Input voltage (110/220 V, switch or auto) | AC 100-240 V, 50/60 Hz[3] | Not documented |
| Total rated power draw | 240 W maximum system power[3] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named. File formats accepted are .ctb and .prz[1][3] | RatOS, Rat Rig's Klipper distribution[5] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch touch panel (control panel — not the masking LCD, see W1)[1][3] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1][3] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; Raspberry Pi and enclosure panels sourced separately[4] |
| Materials Support | ||
| Officially supported filament list | 405 nm photopolymer resin; no closed compatibility list published[1] | Not documented |
| Resin & MSLA | ||
| Masking LCD | 10.1-inch 14K monochrome masking LCD, 13,320 x 5,120 px, XY pixel pitch 16.8 x 24.8 um per Phrozen (3DJake writes 16.8 x 24 um)[3][1] | Not documented |
| Light source | Linear projection LED module. Wavelength not published[3] | Not documented |
| Layer height range | 0.01-0.30 mm[3] | Not documented |
| Release film | nFEP film supplied. No rated life published[1][3] | Not documented |
| Resin vat & feeding | Built-in resin heater fitted; Phrozen publishes no setpoint, no vat capacity, no auto-refill and no level sensing for this model[1][3] | Not documented |
| Fume extraction | Plug-in air purifier supplied with the machine[1] | Not documented |
| Throughputlayers/h | Avg. 450 layers/h on Phrozen's own product page — the only throughput figure Phrozen publishes for this model, and it publishes no mm/h at all. 3DJake states 400 layers/h for the same machine; Phrozen's own figure is used here, as elsewhere in this entry. Manufacturer claim, not a measurement, and neither source states the layer height assumed. W4 is deliberately empty: the layer range is 0.01-0.30 mm, so any mm/h conversion would be invented rather than measured[3][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.
