Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[1]Sovol SV06 Plus ACE 3D Printer[2][3]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[4]Not documented
Street price (USD; dated snapshot per entry)$219.00 on us.elegoo.com, Aug 2026, against a compare-at price of $249.00; both the Ribbon-Cable and Type-C printhead variants are the same price[4]$299.00 on sovol3d.com against a $349.00 compare-at price, in stock and shipping from US/EU/CA/AU/UK/CN warehouses, checked Aug 2026[2][3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Two printhead variants of the same machine are sold under one SKU - "Ribbon-Cable Version" and "Type-C Version" - which use different printhead parts. Within the Neptune 4 family the numbers diverge sharply and get mixed up constantly: Neptune 4 is 225 x 225 x 265 mm with a 110 C bed and 20000 mm/s2; the Plus is 320 x 320 x 385 mm with a 100 C bed and 12000 mm/s2; the Max is 420 x 420 x 480 mm with an 85 C bed and only 8000 mm/s2. The Neptune 4 Pro is a separate model again[4][1][5][6]Larger sibling of the SV06 ACE ($239, 220x220x250). Differs from the non-ACE SV06 Plus by Z height (350 vs 340 mm), Klipper on an RK3308, ceramic-plate hotend, 4.3-inch capacitive touchscreen and a camera. Notably it has NO power-loss recovery, which the older SV06 did have[2][3][7]
Market position: superseded? successor announced?Still listed in ELEGOO's US store Neptune section in Aug 2026 alongside the 4 Pro, 4 Plus and 4 Max, but ELEGOO's current development is on the Centauri line[8]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[1]300 x 300 x 350 mm advertised[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)475 x 445 x 515 mm. ELEGOO separately publishes a "maximum size for machine activity" of 475 x 550 x 735 mm including rack and tray - the depth to allow for is 550 mm, not 445 mm[1]510 x 575 x 710 mm including screen and filament holder[2]
Net weight (kg)8.3 kg net, 10.6 kg gross[1]Not documented
Frame construction & materialCNC-machined aluminium extrusion frame[1]Open i3-style frame; Sovol publishes no frame-material breakdown[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame, no enclosure[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]Cartesian i3 bedslinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[9]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)"Silent Drive (All Axes)" is all ELEGOO publishes; no driver part number is given[9]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim); the Neptune 4 Plus page for the same family states a recommended 250 mm/s[1][5]500 mm/s maximum (manufacturer claim)[2]
Recommended/typical print speed250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[9]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 max toolhead acceleration (manufacturer claim) - notably higher than the Plus at 12000 and the Max at 8000, because the moving mass is smaller[1][5][6]15,000 mm/s2 maximum (manufacturer claim)[2]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[9]Planetary double-gear direct drive, 1:7.5 reduction[2]
Gear ratio & drive gear materialNot documented1:7.5[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, with a copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[9]Ceramic heating plate hotend; 0.4 mm nozzle included, 0.6 and 0.8 mm optional[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]<=300 °C claimed[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heated bed temperature[1]100 °C claimed[2]
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[9]Double-sided textured PEI plate[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Manual levelling combined with 121-point auto-levelling; no full-auto calibration on this model[9]Automatic levelling (Sovol calls the ACE upgrade an added automatic levelling function); probe technology not named on this page[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection fitted; power-loss resume printing supported[1]Filament run-out sensor fitted; type and location not published[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)ELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU published[9]Not documented
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documentedRockchip RK3308 ("3308 chip"), 512 MB RAM, 8 GB eMMC[2]
PSU (brand, wattage, rail voltage)Not documented500 W / 24 V, 100-240 VAC 50/60 Hz[2]
Input voltage (110/220 V, switch or auto)115/230 V, 50/60 Hz on the product page; ELEGOO's compare page gives 110-120 / 220-240 VAC 50/60 Hz[1][9]Not documented
Total rated power draw310 W rated power, 24 V output[9]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 series, rather than the ELEGOO OS branding used on the Centauri machines)[9][10]Klipper. Sovol does not publish the fork or version on the product page. OTA updates supported[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[9]4.3-inch capacitive touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[9]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveLAN and USB file transfer; no Wi-Fi is listed for the base Neptune 4, unlike the Plus (USB/LAN/Wi-Fi) and Max (Wi-Fi/USB/WLAN)[1][5][6]Wi-Fi 2.4 GHz only, WPA2 only (WPA3 explicitly not supported)[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedBuilt-in camera, default 640x480, maximum 1280x720 (Sovol writes it as 1080x720P)[2]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedNone. Sovol's own spec table states "Power Loss Recovery: None" for this model[2]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA, Nylon[1]PLA, PETG, TPU, PVA[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Operating sound published as 60 dB or less - a manufacturer figure with no distance or method stated, so it is not comparable with an independently measured reading[9]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.
