Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 3 Pro[1]Prusa CORE One L+[2]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 11 November 2022 (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)$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[3][5]$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[6][7]
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][8][9]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][7][6]
Market position: superseded? successor announced?Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[9]Not documented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]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 - the same body as the Neptune 4. ELEGOO's maximum size for machine activity is 475 x 580 x 725 mm[1][8]469 x 521 x 635 mm[2]
Net weight (kg)8.1 kg net, 10.15 kg gross[1]21.9 kg (48.3 lb)[2]
Frame construction & materialCNC-machined aluminium extrusion frame (Neptune family)[8]Not documented
Enclosure: open / enclosed; panel material; door/lidOpen 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 documentedActive 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[7]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo 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]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)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]Not documented
Recommended/typical print speed60 mm/s recommended printing speed (manufacturer figure)[1]Not documented
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput Shaper and Phase Stepping with an integrated accelerometer[2]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[1]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 materialNot documented10:1 planetary gearbox[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, titanium-alloy heat break[1]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)260 C claimed max nozzle temperature - 40 C below the Neptune 4 series[1][8]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 limit100 C max heated bed temperature at 25 C ambient[1]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet[1]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)36-point auto-levelling (the Neptune 4 family moved to 121 points)[1][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 run-out sensor and power-loss recovery[1]Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[2]
Electronics & Power

Total rated power draw300 W rated power, 24 V output[1]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)Marlin - ELEGOO names the system "Marlin" for the Neptune 3 Pro, against "Klipper" for the whole Neptune 4 family[1][10]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[11][12]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[1]3.5-inch 65k-colour touch screen (CORE One family)[7]
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[1]On-device touch UI with Prusa Connect and Prusa mobile app remote control[7]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveTF (microSD) card and USB cable only - no LAN and no Wi-Fi[1]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 listPLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][8]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 documentedOpen-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[13][11]
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[14]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[15][12]

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.
