Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 Max[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)[3]Not documented
Street price (USD; dated snapshot per entry)$389.00 on us.elegoo.com, Aug 2026, against a compare-at price of $559.99; Ribbon-Cable and Type-C printhead variants are the same price[3]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Largest Neptune 4. The trade-off against the smaller models is easy to miss: the bed only reaches 85 C (against 100 C on the Plus and 110 C on the base Neptune 4) and acceleration is capped at 8000 mm/s2 (against 12000 and 20000), because of the mass of a 430 x 430 mm moving bed. Two printhead variants, Ribbon-Cable and Type-C, are sold under one SKU[1][4][5][3]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 usable420 x 420 x 480 mm; printing platform 430 x 430 mm[1]180 x 180 x 165 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)658 x 632 x 740 mm; ELEGOO's maximum size for machine activity is 658 x 950 x 960 mm including rack and tray - allow nearly a metre of depth and height[1]200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[2]
Net weight (kg)18.1 kg net, 21.8 kg gross[1]3 kg net; 5.5 kg with the hard case[2]
Frame construction & materialCNC-machined aluminium extrusion frame[1]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[6]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)"Silent Drive (All Axes)"; no driver part number published[6]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim)[1]250 mm/s maximum print speed (manufacturer claim)[2]
Recommended/typical print speed250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[6]Not documented
Max acceleration (claimed, mm/s²)8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[1]8,000 mm/s2 (manufacturer claim)[2]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[6]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[6]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 limit85 C max heated bed temperature at 25 C ambient - well below the 100-110 C of the smaller Neptunes, which limits ABS/ASA work despite them being on the compatibility list[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, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[6]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[6]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection and power-loss resume printing[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)"Klipper High-Speed Quiet Motherboard" is all ELEGOO publishes[6]LDO Positron mainboard[2]
PSU (brand, wattage, rail voltage)Not documentedDC 24 V, 200 W[2]
Input voltage (110/220 V, switch or auto)100-120 V / 220-240 V, 50/60 Hz[1][6]Not documented
Total rated power draw320 W rated power, 24 V output[6]Not documented
Firmware & Openness

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 - but note the 85 C bed ceiling against ABS and ASA[1]PLA and PETG only, per the manufacturer[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Operating sound published as 65 dB or less - a manufacturer figure with no distance or method stated[6]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[7]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.
