Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 Plus[1]UltiMaker S8 3D Printer[2][3]
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[4][5]Launched March 2025; the technical-specification and pricing announcement is dated 14 March 2025[3]
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[4][6][5]Starting at $8,999 at MatterHackers, in stock, checked Aug 2026. The launch announcement quoted approximately $9,000[2][3]
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][7][8][9]Sold as printer-only or as a Pro Bundle. The bundle is not a trim level but a different machine footprint and weight: 495 x 500 x 1210.5 mm and 47.7 kg with the 6-spool Material Station, versus 495 x 585 x 800.5 mm and 30 kg for the printer alone. Print cores AA+ 0.40 x2 are included; BB, CC+ and DD 0.40 are separate purchases[2][3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable320 x 320 x 385 mm; printing platform 330 x 330 mm[1]330 x 240 x 300 mm[2][3]
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]495 x 585 x 800.5 mm printer only; 495 x 500 x 1210.5 mm as the Pro Bundle[2][3]
Net weight (kg)14.4 kg net, 16.65 kg gross[1]30 kg printer only; 47.7 kg as the Pro Bundle[2][3]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]Dual-extrusion print head with auto nozzle-lifting, flood detection and inductive probing. UltiMaker's Cheetah motion planner uses third-order continuous motion with corner blending[2][3]
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]Up to 500 mm/s in XY (manufacturer claim)[2][3]
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]Up to 50,000 mm/s2 (manufacturer claim)[2][3]
Jerk / square-corner-velocity setting (exact value)Not documentedJerk up to 100,000,000 mm/s3 (manufacturer claim)[2][3]
Max volumetric flow claimed (mm³/s)Not documentedUp to 35 mm3/s extrusion flow (manufacturer claim)[2][3]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[1][9]Dual gripper feeder with tension adjustment, release function and filament feed-rate control[2][3]
Filament diameterNot documented2.85 mm[2][3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, with a titanium-alloy heat break[1]Swappable print cores; AA+ 0.40 x2 included, BB 0.40 / CC+ 0.40 / DD 0.40 sold separately[2][3]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]Up to 340 °C (manufacturer claim)[2][3]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient[1]Up to 120 °C on a flexible PEI plate (manufacturer claim)[2][3]
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]Flexible PEI plate[2][3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Manual levelling combined with 121-point auto-levelling[1]Inductive probing, integrated into the print head[2][3]
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

Cooling & Air Handling
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documentedAir Manager, which UltiMaker says removes up to 95% of ultrafine particles[2][3]
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]Not documented
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][9]Not published; print preparation is UltiMaker Cura 5.10 or newer, fleet management via UltiMaker Digital Factory[2][3]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[1]Not documented
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 2.4 and 5 GHz (802.11a/b/g/n/ac), Gigabit Ethernet, USB 2.0[2][3]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedFull HD HDR camera[2][3]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA, Nylon[1]UltiMaker cites 301+ compatible materials including its own PLA, PETG, ABS, CPE, CPE+, PC, TPU and PET-CF, plus third-party grades[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]Under 50 dBA operating sound, manufacturer figure. No independent measurement; distance and method not stated[2][3]
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]12 months, extendable to 5 years with an UltiMakerCare plan[2][3]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedDimensional accuracy +/-0.15 mm +/-0.15% of feature nominal length (manufacturer specification, not an independent measurement)[2][3]

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.
