Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 3 Pro[1]Sovol Zero 3D Printer[2][3]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 11 November 2022 (Shopify publish date)[4]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[4][5]$389.00 on sovol3d.com against a $499.00 compare-at price, but marked Sold out, checked Aug 2026. Sovol's own announcement article quotes from $359.00[2][3][6]
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]No sibling variants at the time of checking. Sovol positions it against the Voron 0 and Bambu Lab P1P. Note the bed and nozzle limits are higher than the larger SV08 (120 vs 100 °C bed, 350 vs 300 °C nozzle), so SV08 figures must not be carried across[2][6][9]
Market position: superseded?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Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[8]Not documented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]152.4 x 152.4 x 152.5 mm advertised[2][6]
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]345 x 420 x 475 mm[2]

Frame construction & materialCNC-machined aluminium extrusion frame (Neptune family)[7]Full linear rails on all axes; CoreXY with two motors sharing the moving mass[6]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed[6]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]CoreXY[6]

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]1200 mm/s maximum (manufacturer claim). Sovol's own material acknowledges 700 mm/s as the realistic figure for detailed prints[2][6]
Recommended/typical print speed60 mm/s recommended printing speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)Not documented40,000 mm/s2 maximum (manufacturer claim)[2][6]
Max volumetric flow claimed (mm³/s)Not documented<=50 mm3/s (manufacturer claim)[2]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[1]Planetary-gear direct-drive extruder[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, titanium-alloy heat break[1]Ceramic heating plate. Brass or hardened-steel nozzles in 0.2/0.4/0.6/0.8/1.0 mm[2]
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]<=350 °C claimed[2][6]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedBrass or hardened steel, buyer's choice[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient[1]<=120 °C claimed; Sovol states the bed is AC-heated[2][6]
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet[1]Double-sided PEI steel plate[2]
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][10]Eddy-current scanning combined with pressure (force) sensing — Sovol describes it as an inductive sensor plus force sensor[2][6]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor and power-loss recovery[1]Filament sensor fitted; type and location not published[2][6]
Electronics & Power
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documentedAllwinner H616, 1 GB RAM, 8 GB eMMC, 64-bit[2]
PSU (brand, wattage, rail voltage)Not documented150 W / 24 V (this is the DC supply; the bed is separately AC-heated per Sovol)[2][6]
Total rated power draw300 W rated power, 24 V output[1]Not documented
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][10]Not named on the product page beyond OTA updates and OrcaSlicer support; Sovol markets the machine as open source[2][6]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[1]Not documented
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[1]Not documented

Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedBuilt-in camera for monitoring; resolution not published[2][6]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedArrives preassembled[6]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery supported; mechanism not published[2][6]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][7]PLA, PETG, TPU, PETG-CF, ABS, ASA, PA, PC[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[11]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.
