Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[1]Prusa CORE One+ (Gen 2) INDX, listed as "INDX 4-Tool" and "INDX 8-Tool" variants and as an "INDX 8-Tool Assembly kit"[2][3]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[4]Announced as shipping on 20 August 2026 ("INDX, Shipping Has Started, Complete Printers Open for Orders"). Prusa's own front page in Aug 2026 announces "Prusa CORE One+ (Gen 2) INDX, Shipping Has Started, Complete Printers Open for Orders", with the assembled 8-tool machine quoted as shipping from 15 October and the kit from 29 October[5][2]
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[4]$1,850.93 for the INDX 4-Tool and $2,082.41 for the INDX 8-Tool on prusa3d.com, Aug 2026; the 8-Tool assembly kit is $1,804.63. Camera and filtration bundles run to $2,152.78[2][3]
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[4][1][6][7]INDX is a multi-tool option on the CORE One+ (Gen 2) product page rather than a separate printer, sold in 4-tool and 8-tool configurations, plus a CORE One/+ INDX conversion kit for existing machines. All of the body, hotend, bed and electronics figures below come from that shared CORE One+ (Gen 2) page and were not published separately for the INDX machine, so treat them as platform figures. Prusa also sells the unrelated MMU3, which multiplexes five filaments through one nozzle[3][2]
Market position: superseded?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[8]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]250 x 220 x 270 mm - the CORE One+ (Gen 2) figure from the shared product page; Prusa does not publish a separate INDX build volume[3]
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]415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[3]
Net weight (kg)8.3 kg net, 10.6 kg gross[1]Not documented
Frame construction & materialCNC-machined aluminium extrusion frame[1]Not documented
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed with active chamber heating up to 55 C (shared CORE One+ platform)[3]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]CoreXY with a multi-tool head-changing system (INDX); Prusa's comparison table gives CoreXY for the CORE One family[3]
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)[9]Not documented
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[9]Not documented
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][6]Not documented
Recommended/typical print speed250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[9]Not documented
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][6][7]Not documented
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[9]Nextruder direct drive, 10:1 planetary gearbox (shared platform)[3]
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[9]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]290 C claimed max nozzle temperature, 400 C with the optional HT hotend (shared platform)[3]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heated bed temperature[1]120 C max heatbed temperature (shared platform)[3]
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[9]Not documented
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[9]Load-cell sensor, fully automatic first-layer calibration (shared platform)[3]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection fitted; power-loss resume printing supported[1]Filament sensors fitted (two on the CORE One+ platform)[3]
Multi-material/multi-color capability or official upgrade pathNot documentedINDX gives up to eight filaments; the alternative MMU3 handles five through a single nozzle[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 published[9]Custom 32-bit xBuddy board with STM32 (shared platform)[3]
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][9]Not documented
Total rated power draw310 W rated power, 24 V output[9]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)[9][10]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[11][12]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[9]3.5-inch 65k-colour touch screen (shared platform)[3]
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[9]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][6][7]Ethernet and Wi-Fi, USB drive (shared platform)[3]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA, Nylon[1]PLA, PETG, Flex, PVA, PC, PP, CPE, PVB; ABS, ASA, HIPS and PA as advanced materials in the heated chamber (shared platform)[3]
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[9]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[13]2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[14][12]

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.
