| Brand | ELEGOO | Sovol |
| Class | BEDSLINGER | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 3 Pro[1] | Sovol SV06 Plus ACE 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] | $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) | 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][6][7] | 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][8] |
| Market position: superseded? successor announced? | Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[7] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 225 x 225 x 280 mm; printing platform 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 - the same body as the Neptune 4. ELEGOO's maximum size for machine activity is 475 x 580 x 725 mm[1][6] | 510 x 575 x 710 mm including screen and filament holder[2] |
| Net weight (kg) | 8.1 kg net, 10.15 kg gross[1] | Not documented |
| Frame construction & material | CNC-machined aluminium extrusion frame (Neptune family)[6] | Open i3-style frame; Sovol publishes no frame-material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open 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-backlash | Two lead screws[1] | Not documented |
| 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] | 500 mm/s maximum (manufacturer claim)[2] |
| Recommended/typical print speed | 60 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | Not documented | 15,000 mm/s2 maximum (manufacturer claim)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[1] | Planetary double-gear direct drive, 1:7.5 reduction[2] |
| Gear ratio & drive gear material | Not documented | 1:7.5[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass nozzle, 0.4 mm, titanium-alloy heat break[1] | 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) | 260 C claimed max nozzle temperature - 40 C below the Neptune 4 series[1][6] | <=300 °C claimed[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heated bed temperature at 25 C ambient[1] | 100 °C claimed[2] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet[1] | Double-sided textured PEI 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][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 run-out sensor and power-loss recovery[1] | Filament run-out sensor fitted; type and location not published[2] |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Rockchip RK3308 ("3308 chip"), 512 MB RAM, 8 GB eMMC[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 500 W / 24 V, 100-240 VAC 50/60 Hz[2] |
| Total rated power draw | 300 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][9] | 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[1] | 4.3-inch capacitive touchscreen[2] |
| 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-drive | TF (microSD) card and USB cable only - no LAN and no Wi-Fi[1] | 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 documented | Built-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 documented | None. Sovol's own spec table states "Power Loss Recovery: None" for this model[2] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][6] | PLA, PETG, TPU, PVA[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 |
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.
