| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[1] | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[4] | Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[5] |
| 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] | $649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[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] | Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[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| Market position: superseded?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in Aug 2026 alongside the 4 Pro, 4 Plus and 4 Max, but ELEGOO's current development is on the Centauri line[8] | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[9][10] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[1] | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][5] |
| 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] | 505 x 487 x 550 mm[5] |
| Net weight (kg) | 8.3 kg net, 10.6 kg gross[1] | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] |
| Frame construction & material | CNC-machined aluminium extrusion frame[1] | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][5] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[2][5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | CoreXY[5] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[11] | Dual independent Z motors on 10 mm linear shafts and screws[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[11] | 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] | 600 mm/s (manufacturer claim, tool-head maximum)[5] |
| Recommended/typical print speed | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[11] | 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] | <=20,000 mm/s2 (manufacturer claim)[5] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[11] | Direct drive with hardened steel dual gears, 1.75 mm filament[2][5] |
| 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[11] | Second-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[2][5] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | <=370 °C claimed. No firmware max_temp verified for this model[2][5] |
| Heater cartridge power (W) | Not documented | 80 W hotend heater (manufacturer figure)[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature[1] | Conflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[2][5] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[11] | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][5] |
| 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[11] | Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted; power-loss resume printing supported[1] | Filament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[5] |
| Multi-material/multi-color capability or official upgrade path | Not documented | QIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[2][3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Auxiliary part-cooling fan plus a chamber circulation fan; fan sizes and duct design not published[5] |
| 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[11] | Not documented |
| 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][11] | 100-240 VAC, 50/60 Hz[5] |
| Total rated power draw | 310 W rated power, 24 V output[11] | 450 W plus 400 W for chamber heating (rated)[5] |
| 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)[11][12] | Klipper v0.12, described by QIDI as open source. Fork details and current release not published on the product page[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[11] | 5-inch touchscreen, 800 x 480[2][5] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[11] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | LAN 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] | Wi-Fi 2.4 GHz, Ethernet, USB[2][5] |
| Cloud service & phone app; LAN-only mode possible? | Not documented | Mobile and computer control, remote cloud or LAN-only operation[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in low-frame-rate camera, up to 1080p, timelapse supported[2][5] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | QIDI claims about 10 minutes from unbox to printing[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery listed; mechanism not published[5] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA, Nylon[1] | PLA, ABS, ASA, PETG, TPU, PA, PC, PA-CF/GF, PET-CF/GF, PPA-CF/GF, PPS-CF and other CF/GF-filled polymers[2][5] |
| 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[11] | 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] | 1-year coverage, 14-day no-reason return, 30-day price protection[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.
