|---|---|---|

| Brand | Phrozen | Prusa Research |
| Class | RESIN | COREXY |
| 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] | Prusa CORE One L+[4] |
| Release date (announcement and actual shipping) | Not documented | The CORE One L+ refresh was announced on 13 August 2026 and went on sale immediately, with the first assembled units shipping at once; it adds GT1.5 belts and an integrated nozzle wiper to the CORE One L[5] |
| 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] | $1,850.93 on prusa3d.com, Aug 2026; $1,925.00 with the Advanced Filtration bundle. Prusa's own comparison text on the CORE One+ page quotes "from $1,799", which does not match the live e-shop price[6][7] |
| 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] | Larger sibling of the CORE One+ (Gen 2): 300 x 300 x 330 mm against 250 x 220 x 270 mm, 60 C chamber against 55 C, 21.9 kg against 22.5 kg (the L is the lighter of the two despite being larger). A CORE One L to CORE One L+ upgrade kit exists, so "CORE One L" and "CORE One L+" are different revisions. A Critical Infrastructure Edition is also listed[4][7][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 223 x 126 x 235 mm[1][3] | 300 x 300 x 330 mm, which Prusa states as 29.7 litres[4] |
| 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] | 469 x 521 x 635 mm[4] |
| Net weight (kg) | 18 kg[3] | 21.9 kg (48.3 lb)[4] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a UV-blocking cover[1] | Fully enclosed with a chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active convection chamber heating, maximum 60 C (manufacturer figure)[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 - stated in Prusa's CORE One+ comparison table[7] |
| 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 | Trinamic drivers on the custom xBuddy mainboard (Prusa's CORE One L+ specification says "custom 32-bit xBuddy mainboard with STM32 processor & Trinamic drivers"; it does not give the driver part number)[4] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input Shaper and Phase Stepping with an integrated accelerometer[4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Nextruder direct drive with a 10:1 planetary gear system; all-metal hotend with an aluminium heatsink and a tool-free quick-swap nozzle system[4] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox[4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Tool-free quick-swap nozzle system; Prusa brass high-flow CHT 0.4 mm pre-mounted plus an abrasive-resistant 0.4 mm nozzle in the box[4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 290 C claimed max nozzle temperature. The optional HT hotend that raises this to 400 C was announced for September 2026 availability, so it is not a shipping specification as of Aug 2026[4][5] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 120 C max heatbed temperature[4] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Magnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling[1] | High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[4] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Custom 32-bit xBuddy mainboard with an STM32 processor[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] | Standby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (manufacturer figures)[4] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named. File formats accepted are .ctb and .prz[1][3] | Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[8][9] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch touch panel (control panel — not the masking LCD, see W1)[1][3] | 3.5-inch 65k-colour touch screen (CORE One family)[7] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Not documented | On-device touch UI with Prusa Connect and Prusa mobile app remote control[7] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1][3] | Ethernet, NFC receiver and Wi-Fi through a physically removable module, which Prusa offers for high-security offline installations[4] |
| Materials Support | ||
| Officially supported filament list | 405 nm photopolymer resin; no closed compatibility list published[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and with Advanced Filtration also ABS, ASA, HIPS and PA[4] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[10][8] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[11][9] |
| 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.
