Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 Plus[1]LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[2]
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[3][4]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[3][5][4]Not documented
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][6][7][8]The defining trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable320 x 320 x 385 mm; printing platform 330 x 330 mm[1]180 x 180 x 165 mm[2]
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]200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[2]
Net weight (kg)14.4 kg net, 16.65 kg gross[1]3 kg net; 5.5 kg with the hard case[2]
Frame construction & materialCNC-machined aluminium extrusion frame (Neptune 4 family)[6]Folding frame designed to fit in a filament box; supplied with a black hard case[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]CoreXY, inverted — the machine prints upside down[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo 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]250 mm/s maximum print speed (manufacturer claim)[2]
Recommended/typical print speed250 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]8,000 mm/s2 (manufacturer claim)[2]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[1][8]Bowden-style, single extrusion[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, with a titanium-alloy heat break[1]PS plated-copper nozzle, 0.4 mm[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]260 °C maximum (manufacturer claim)[2]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedPlated copper[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient[1]85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[2]
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet; ELEGOO notes it is now upgraded to a dual-sided textured PEI + PLA-specific surface[1]Heated removable ITO glass bed[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]Not documented
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]Not documented
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]LDO Positron mainboard[2]
PSU (brand, wattage, rail voltage)Not documentedDC 24 V, 200 W[2]
Total rated power draw320 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][8]Klipper[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[1]3.5-inch LCD touchscreen[2]
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-driveUSB, LAN and Wi-Fi[1]Wi-Fi, USB, Ethernet[2]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit, manufactured in China[2]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA, Nylon[1]PLA and PETG only, per the manufacturer[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[9]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.
