Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 3 Pro[1]Voron 2.4, current revision R2, kits shipping as Rev D and Rev D+. Sold as "Voron 2.4 R2 (Rev D+) 3D Printer Kit by LDO"[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]$1,399.99 for the LDO Rev D+ kit at Fabreeko (300 mm and 350 mm are the same price), on pre-order with a mid-September estimate, checked Aug 2026. Fabreeko's live feed shows the base 2.4 kit listing at $1,299.99 and available. 3DJake lists an LDO 350 RevD kit but will not ship to the US[2][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]Sizes 250, 300 and 350 mm; LDO ships Rev D and Rev D+. Colours black, space grey, blue. Do not confuse with the Trident: the 2.4 lifts the whole gantry on four belted Z motors, the Trident lifts the bed on three screws. The Rev D+ kit includes a Raspberry Pi 4B; the older 3DJake-listed RevD kit explicitly does not include a Pi[2][3][7][10]
Market position: superseded? successor announced?Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[9]Not documented

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 300 mm or 350 x 350 x 350 mm. Sortable value is the 350 mm kit[2][3][7]
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]Not documented
Net weight (kg)8.1 kg net, 10.15 kg gross[1]Not documented
Frame construction & materialCNC-machined aluminium extrusion frame (Neptune family)[8]Blind-joint aluminium-extrusion frame with a complete panel set; stainless-steel linear rails throughout[3][7]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]CoreXY on linear rails, with a belted flying gantry on four Z motors[3][2]
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]LDO Leviathan board: 5 x TMC2209 plus 2 x TMC5160 HV-capable drivers, ready for 48 V upgrades[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
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[1]Clockwork 2 with a Bondtech BMG / Integrated Drive Gear Assembly, in a Stealthburner toolhead[2][3][7]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, titanium-alloy heat break[1]E3D Revo Voron (24 V), all-metal, high-flow variant in the Rev D+ kit, with a 60 W heater; upgradeable to a Phaetus Rapido HF for $9.99[2][3][7]
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]Not documented
Heater cartridge power (W)Not documented60 W (E3D Revo High Flow heater)[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient[1]Not documented
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet[1]Cast 5083 aluminium plate with a magnetic base and a powder-coated PEI sheet; LDO silicone bed heater with edge-to-edge heating[3][2][7]
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][11]Omron inductive probe supplied; Klicky-mod parts included. Voron Tap is available as an add-on rather than standard[2][3]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor and power-loss recovery[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedLDO x Voron Leviathan mainboard (replacing the earlier BTT Octopus), plus a Nitehawk SB USB toolhead PCB[3][2][7]
Total rated power draw300 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][11]Klipper, hosted on a Raspberry Pi 4B (included in the Fabreeko Rev D+ kit, not in the older 3DJake RevD kit)[2][3][7]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[1]4.3-inch touchscreen included in the LDO kit[7]
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-driveTF (microSD) card and USB cable only - no LAN and no Wi-Fi[1]Not documented
LED chamber/toolhead lightingNot documentedCOB LED strips included[2][7]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit; some parts must be printed by the user, and the LDO kit supplies pre-cut, pre-crimped cables and a heat-set insert soldering tip[7]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][8]Not documented
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[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.
