Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[1]LulzBot TAZ Pro (LulzBot's own store lists it under Legacy LulzBot printers)[2]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[3]Not documented
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]$4,950.00 on buy.lulzbot.com, in stock, checked Aug 2026[2]
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][4][5]Several TAZ Pro derivatives exist and their specs differ substantially: TAZ Pro S, TAZ Pro XT+, and TAZ Pro Long Bed (282 x 582 x 285 mm, 1.2 mm GammaMaster steel nozzle, 80 °C bed cap, 150 mm/s travel, BLTouch 32-point mesh). The base TAZ Pro is 285 mm cubed with a 0.5 mm hardened-steel nozzle, a 110 °C bed and 300 mm/s travel — do not mix the two spec sets[2][6]
Market position: superseded?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[7]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[1]285 x 285 x 285 mm[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]Not documented
Net weight (kg)8.3 kg net, 10.6 kg gross[1]Not documented
Frame construction & materialCNC-machined aluminium extrusion frame[1]Open frame; movement on GT2 belts with Igus SST rods and polymer bushings[2]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]Cartesian bedslinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[8]Not documented
Belts (type, width, e.g. Gates?)Not documentedGT2 belt drive[2]
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[8]Trinamic TMC2130[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][4]Not documented
Recommended/typical print speed250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[8]Not documented
Max travel speedNot documented300 mm/s maximum travel speed (manufacturer figure)[2]
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][4][5]Not documented
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[8]Pro Dual Extruder tool head — two active-lifting hot ends for true dual-material printing[2]
Filament diameterNot documented2.85 mm standard, 1.75 mm optional[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[8]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]290 °C maximum hot end temperature[2]
Stock nozzle size & sizes included in boxNot documented0.5 mm hardened steel[2]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedHardened steel[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heated bed temperature[1]110 °C maximum bed temperature[2]
Bed heater type (DC/AC mains) & wattageNot documented360 W, 24 V silicone bed heater[2]
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[8]Dual-sided borosilicate glass with PEI film[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[8]Automatic 4-point mesh levelling using a 5 V contact circuit, plus automatic X-axis tramming, Z-offset and backlash compensation[2]
Mesh grid size (probe point count — firmware evidence)Not documented4-point mesh[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection fitted; power-loss resume printing supported[1]Filament sensor with both runout and stripping detection[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[8]32-bit Archim 2.2b with Trinamic TMC2130 drivers[2]
PSU (brand, wattage, rail voltage)Not documented500 W 24 V Mean Well, auto-switching, 100-240 VAC input[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][8]Not documented
Total rated power draw310 W rated power, 24 V output[8]Not documented
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)[8][9]Marlin[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[8]5-inch full-colour resistive touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[8]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveLAN 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][4][5]USB serial; a 16 GB flash drive is included for standalone printing[2]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA, Nylon[1]PLA, TPU, ABS, PETG, PVA, PVB, nylon, PC and other materials below 290 °C[2]
Safety
Certifications (UL/ETL/CE/FCC — verify, don't assume)Not documentedFCC, CE, RCM, ETL, CSA, OSHWA and WEEE. The OSHWA listing is the open-hardware certification[2]
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[8]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[10]1 year standard, with extended options. Made in the USA[2]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedPositional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification, not an independent measurement)[2]

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.
