| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 4 Plus[1] | Sovol Zero 3D Printer[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date), the same date as the Neptune 4 Max[4][5] | Not documented |
| Street price (USD; dated snapshot per entry) | $309.00 on us.elegoo.com, Aug 2026, against a compare-at price of $425.00. Only a Ribbon-Cable printhead variant is listed for the Plus, unlike the Neptune 4 and 4 Max which also offer a Type-C version[4][6][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][7] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Middle model of the Neptune 4 family. Against the base Neptune 4: bigger (320 x 320 x 385 mm), but a lower bed ceiling (100 C rather than 110 C) and much lower acceleration (12000 rather than 20000 mm/s2). Against the Max: smaller and lighter (14.4 kg against 18.1 kg) but with a higher bed ceiling (100 C against 85 C) and higher acceleration (12000 against 8000). Its Z drive is 2 lead screws with 2 tie rods, where the Centauri machines use 3 lead screws[1][8][9][10] | 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][7][11] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 320 x 320 x 385 mm; printing platform 330 x 330 mm[1] | 152.4 x 152.4 x 152.5 mm advertised[2][7] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 533 x 517 x 638 mm; ELEGOO also publishes a maximum size for machine activity of 578 x 750 x 860 mm including rack and tray, so allow 750 mm of depth[1] | 345 x 420 x 475 mm[2] |
| Net weight (kg) | 14.4 kg net, 16.65 kg gross[1] | Not documented |
| Frame construction & material | CNC-machined aluminium extrusion frame (Neptune 4 family)[8] | Full linear rails on all axes; CoreXY with two motors sharing the moving mass[7] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Fully enclosed[7] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | CoreXY[7] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear rails on all axes[7] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two lead screws with two tie rods[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)" is all ELEGOO publishes; the driver part number is not given on the product page[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 30-500 mm/s printing speed, with 250 mm/s given by ELEGOO as the recommended figure - the 500 mm/s number is a ceiling, not a working speed[1] | 1200 mm/s maximum (manufacturer claim). Sovol's own material acknowledges 700 mm/s as the realistic figure for detailed prints[2][7] |
| Recommended/typical print speed | 250 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 12000 mm/s2 maximum acceleration; default acceleration 5000 mm/s2[1] | 40,000 mm/s2 maximum (manufacturer claim)[2][7] |
| Max volumetric flow claimed (mm³/s) | Not documented | <=50 mm3/s (manufacturer claim)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[1][10] | Planetary-gear direct-drive extruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass nozzle, 0.4 mm, with a 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) | 300 C claimed max nozzle temperature[1] | <=350 °C claimed[2][7] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass or hardened steel, buyer's choice[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heated bed temperature at 25 C ambient[1] | <=120 °C claimed; Sovol states the bed is AC-heated[2][7] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet; ELEGOO notes it is now upgraded to a dual-sided textured PEI + PLA-specific surface[1] | Double-sided PEI steel 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[1] | Eddy-current scanning combined with pressure (force) sensing — Sovol describes it as an inductive sensor plus force sensor[2][7] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor and power-loss recovery; no camera, no clog detection, no auto filament unloading[1] | Filament sensor fitted; type and location not published[2][7] |
| 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 is published[1] | Not documented |
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Allwinner H616, 1 GB RAM, 8 GB eMMC, 64-bit[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 150 W / 24 V (this is the DC supply; the bed is separately AC-heated per Sovol)[2][7] |
| Total rated power draw | 320 W rated power; 24 V output; 110-120 V / 220-240 V input[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 Plus, rather than the ELEGOO OS branding used on the Centauri machines)[1][10] | Not named on the product page beyond OTA updates and OrcaSlicer support; Sovol markets the machine as open source[2][7] |
| 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 is recommended, with Orca and Cura also supported[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB, LAN and Wi-Fi[1] | Ethernet and Wi-Fi 2.4 GHz, WPA2 only (WPA3 not supported)[2][7] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in camera for monitoring; resolution not published[2][7] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Arrives preassembled[7] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery supported; mechanism not published[2][7] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA, Nylon[1] | PLA, PETG, TPU, PETG-CF, ABS, ASA, PA, PC[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound is published as 65 dB or less - a manufacturer figure with no measuring distance or method given, so it is not comparable with a reviewer's dB reading[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[12] | 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.
