Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 3 Pro[1]Phrozen Sonic Mighty Revo 14K 10.1" LCD 3D Printer[2][3][4]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 11 November 2022 (Shopify publish date)[5]Not documented
Street price (USD; dated snapshot per entry)$259.99 on us.elegoo.com, Aug 2026, with the compare-at price also $259.99 - notably more than the newer and far faster Neptune 4 at $219[5][6]$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)The last Neptune 3 still listed; the 3 Plus and 3 Max are gone from the store's Neptune section. Do not read Neptune 4 figures onto it: the 3 Pro runs Marlin, not Klipper, tops out at 180 mm/s rather than 500, uses a 36-point mesh rather than 121-point, and its nozzle stops at 260 C rather than 300 C. Its machine size, 475 x 445 x 515 mm, is identical to the Neptune 4's, so body dimensions will not tell them apart[1][7][8]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]
Market position: superseded? successor announced?Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[8]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable225 x 225 x 280 mm; printing platform 235 x 235 mm[1]223 x 126 x 235 mm[2][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)475 x 445 x 515 mm - the same body as the Neptune 4. ELEGOO's maximum size for machine activity is 475 x 580 x 725 mm[1][7]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)8.1 kg net, 10.15 kg gross[1]18 kg[4]
Frame construction & materialCNC-machined aluminium extrusion frame (Neptune family)[7]Not documented
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open-frame MSLA with a UV-blocking cover[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[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-backlashTwo lead screws[1]Dual linear guide rails with a ball screw[2][4]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)"Silent Drive (All Axes)"; no driver part number published[1]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)30-180 mm/s, with 60 mm/s given by ELEGOO as the recommended speed - a pre-Klipper machine, and the slowest in this file apart from the OrangeStorm Giga[1]Not documented
Recommended/typical print speed60 mm/s recommended printing speed (manufacturer figure)[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[1]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, titanium-alloy heat break[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)260 C claimed max nozzle temperature - 40 C below the Neptune 4 series[1][7]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient[1]Not documented
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)36-point auto-levelling (the Neptune 4 family moved to 121 points)[1][9]Automatic levelling[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor and power-loss recovery[1]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)Not documentedAC 100-240 V, 50/60 Hz[4]
Total rated power draw300 W rated power, 24 V output[1]240 W maximum system power[4]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Marlin - ELEGOO names the system "Marlin" for the Neptune 3 Pro, against "Klipper" for the whole Neptune 4 family[1][9]Not named. File formats accepted are .ctb and .prz[2][4]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[1]5-inch touch panel (control panel — not the masking LCD, see W1)[2][4]
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveTF (microSD) card and USB cable only - no LAN and no Wi-Fi[1]USB and Wi-Fi[2][4]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][7]405 nm photopolymer resin; no closed compatibility list published[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Operating sound published as 48 dB or less - a manufacturer figure with no distance or method stated[1]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[10]Not documented
Resin & MSLA
Masking LCDNot documented10.1-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 sourceNot documentedLinear projection LED module. Wavelength not published[4]
Layer height rangeNot documented0.01-0.30 mm[4]
Release filmNot documentednFEP film supplied. No rated life published[2][4]
Resin vat & feedingNot documentedBuilt-in resin heater fitted; Phrozen publishes no setpoint, no vat capacity, no auto-refill and no level sensing for this model[2][4]
Fume extractionNot documentedPlug-in air purifier supplied with the machine[2]
Throughputlayers/hNot documentedAvg. 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.
