| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[1] | Prusa CORE One L+[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[3] | The CORE One L+ refresh was announced on 13 August 2026 and went on sale immediately, with the first assembled units shipping at once; it adds GT1.5 belts and an integrated nozzle wiper to the CORE One L[4] |
| 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[3] | $1,850.93 on prusa3d.com, Aug 2026; $1,925.00 with the Advanced Filtration bundle. Prusa's own comparison text on the CORE One+ page quotes "from $1,799", which does not match the live e-shop price[5][6] |
| 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[3][1][7][8] | Larger sibling of the CORE One+ (Gen 2): 300 x 300 x 330 mm against 250 x 220 x 270 mm, 60 C chamber against 55 C, 21.9 kg against 22.5 kg (the L is the lighter of the two despite being larger). A CORE One L to CORE One L+ upgrade kit exists, so "CORE One L" and "CORE One L+" are different revisions. A Critical Infrastructure Edition is also listed[2][6][5] |
| Market position: superseded?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[9] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[1] | 300 x 300 x 330 mm, which Prusa states as 29.7 litres[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] | 469 x 521 x 635 mm[2] |
| Net weight (kg) | 8.3 kg net, 10.6 kg gross[1] | 21.9 kg (48.3 lb)[2] |
| Frame construction & material | CNC-machined aluminium extrusion frame[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Fully enclosed with a chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active convection chamber heating, maximum 60 C (manufacturer figure)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | CoreXY - stated in Prusa's CORE One+ comparison table[6] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[10] | 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[10] | Trinamic drivers on the custom xBuddy mainboard (Prusa's CORE One L+ specification says "custom 32-bit xBuddy mainboard with STM32 processor & Trinamic drivers"; it does not give the driver part number)[2] |
| 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][7] | Not documented |
| Recommended/typical print speed | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[10] | 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][7][8] | Not documented |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input Shaper and Phase Stepping with an integrated accelerometer[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[10] | Nextruder direct drive with a 10:1 planetary gear system; all-metal hotend with an aluminium heatsink and a tool-free quick-swap nozzle system[2] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox[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[10] | Tool-free quick-swap nozzle system; Prusa brass high-flow CHT 0.4 mm pre-mounted plus an abrasive-resistant 0.4 mm nozzle in the box[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 290 C claimed max nozzle temperature. The optional HT hotend that raises this to 400 C was announced for September 2026 availability, so it is not a shipping specification as of Aug 2026[2][4] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature[1] | 120 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[10] | Magnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[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[10] | High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted; power-loss resume printing supported[1] | Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[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[10] | Custom 32-bit xBuddy mainboard with an STM32 processor[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][10] | Not documented |
| Total rated power draw | 310 W rated power, 24 V output[10] | Standby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (manufacturer figures)[2] |
| 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)[10][11] | Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[12][13] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[10] | 3.5-inch 65k-colour touch screen (CORE One family)[6] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[10] | On-device touch UI with Prusa Connect and Prusa mobile app remote control[6] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | LAN 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][7][8] | Ethernet, NFC receiver and Wi-Fi through a physically removable module, which Prusa offers for high-security offline installations[2] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA, Nylon[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and with Advanced Filtration also ABS, ASA, HIPS and PA[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[14][12] |
| 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[10] | 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[15] | 2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[16][13] |
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.
