|---|---|---|
| Identity | ||
| Brand | ELEGOO | Prusa Research |
| Class | BEDSLINGER | TOOLCHANGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 4 Max[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 20 September 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) | $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[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) | 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][6][7][4] | 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] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 420 x 420 x 480 mm; printing platform 430 x 430 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) | 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] | 415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[3] |
| Net weight (kg) | 18.1 kg net, 21.8 kg gross[1] | Not documented |
| Frame construction & material | CNC-machined aluminium extrusion frame[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Open 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-backlash | Two lead screws with two tie rods[8] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[8] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim)[1] | Not documented |
| Recommended/typical print speed | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[8] | Not documented |
| Max acceleration (claimed, mm/s²) | 8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[8] | 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 titanium-alloy heat break[8] | 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 limit | 85 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] | 120 C max heatbed temperature (shared platform)[3] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[8] | 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[8] | Load-cell sensor, fully automatic first-layer calibration (shared platform)[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection and power-loss resume printing[1] | Filament sensors fitted (two on the CORE One+ platform)[3] |
| Multi-material/multi-color capability or official upgrade path | Not documented | INDX 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) | "Klipper High-Speed Quiet Motherboard" is all ELEGOO publishes[8] | Custom 32-bit xBuddy board with STM32 (shared platform)[3] |
| Input voltage (110/220 V, switch or auto) | 100-120 V / 220-240 V, 50/60 Hz[1][8] | Not documented |
| Total rated power draw | 320 W rated power, 24 V output[8] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[8] | 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[9][10] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[8] | 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, Orca and Cura supported[8] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB and WLAN file transfer[1] | Ethernet and Wi-Fi, USB drive (shared platform)[3] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA, Nylon - but note the 85 C bed ceiling against ABS and ASA[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 65 dB or less - a manufacturer figure with no distance or method stated[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[11] | 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[12][10] |
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.
