| Property | Formlabs Form 4LRESIN | Phrozen Sonic Mighty Revo 14KRESIN |
|---|---|---|
| Identity | ||
| Brand | Formlabs | Phrozen |
| Class | RESIN | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4L[1] | Phrozen Sonic Mighty Revo 14K 10.1" LCD 3D Printer[2][3][4] |
| Street price (USD; dated snapshot per entry) | Not documented | $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[4][3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Same Low Force Display engine as the Form 4 but a different machine on every physical figure: 353 x 196 x 350 mm vs 200 x 125 x 210, 46 um vs 50 um pixels, 58.5 kg vs 18.3 kg, 900 W vs 480 W, two resin cartridges vs one. Formlabs lists Basic, Premium and Complete packages, whose prices are not printer-only prices, and no printer-only USD figure was found on a live listing[1] | 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[3][2][4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[1] | 223 x 126 x 235 mm[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 664 x 528 x 794 mm[1] | 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[4][2] |
| Net weight (kg) | 58.5 kg[1] | 18 kg[4] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[1] | Open-frame MSLA with a UV-blocking cover[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[1] | MSLA, single Z axis on dual linear guide rails with a ball screw, straight-lift peel[2][4] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Dual linear guide rails with a ball screw[2][4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic levelling[2] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 9 A, 50/60 Hz, 900 W[1] | AC 100-240 V, 50/60 Hz[4] |
| Total rated power draw | 900 W[1] | 240 W maximum system power[4] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary; print preparation is PreForm[1] | Not named. File formats accepted are .ctb and .prz[2][4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1] | 5-inch touch panel (control panel — not the masking LCD, see W1)[2][4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[1] | USB and Wi-Fi[2][4] |
| Materials Support | ||
| Officially supported filament list | Formlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1] | 405 nm photopolymer resin; no closed compatibility list published[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification[1] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Low Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[1] | 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)[4][2] |
| Light source | Backlight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[1] | Linear projection LED module. Wavelength not published[4] |
| Layer height range | 25-200 um[1] | 0.01-0.30 mm[4] |
| Release film | Not documented | nFEP film supplied. No rated life published[2][4] |
| Resin vat & feeding | Two next-generation resin cartridges. No vat capacity published[1] | Built-in resin heater fitted; Phrozen publishes no setpoint, no vat capacity, no auto-refill and no level sensing for this model[2][4] |
| Fume extraction | Not documented | Plug-in air purifier supplied with the machine[2] |
| Throughputlayers/h | Not documented | 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[4][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.
