| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[1] | QIDI Q1 Pro, listed by QIDI as "Q1 Pro 3D Printer". QIDI traded as Qidi Tech until end-2024[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[3] | Not stated on QIDI's own product page; the page now carries a discontinuation notice instead of a launch date (checked Aug 2026)[2][4] |
| 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] | $499.00 on both qidi3d.com and us.qidi3d.com, checked Aug 2026 — but the listing is marked Sold Out and the page states "This model has been discontinued". qidi3d.com shows it against a $599.00 regular price; the US store shows compare-at $499.00[2][4] |
| 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][5][6] | Succeeded by the QIDI Q2, which QIDI's own comparison on the Q1 Pro page distinguishes as 270x270x256 mm (vs 245x245x240), 370 °C hotend (vs 350 °C) and 65 °C chamber (vs 60 °C). Do not read Q2 figures onto the Q1 Pro[2][4] |
| Market position: superseded?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] | Discontinued and out of production; QIDI states spare parts and support for existing owners remain available. Replaced by the Q2[2][4] |
| 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] | 245 x 245 x 240 mm advertised (QIDI). No independently measured usable envelope found[2][8] |
| 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] | 477 x 467 x 489 mm machine dimensions (QIDI)[2][8] |
| Net weight (kg) | 8.3 kg net, 10.6 kg gross[1] | 17 kg net, 20.3 kg gross (QIDI). 3DJake lists the 20.3 kg figure as gross weight[2][8] |
| Frame construction & material | CNC-machined aluminium extrusion frame[1] | Metal CoreXY motion frame with panelled enclosure; QIDI publishes no frame-material breakdown for this model[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Fully enclosed with independent chamber heating to 60 °C; QIDI does not publish the panel materials for this model[2][8] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 60 °C, actively heated (manufacturer claim — this is a heater setpoint, not a measured passive figure)[2][8] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | CoreXY[8] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | 10 mm linear steel rods with automatically tensioned belt (manufacturer description)[8] |
| 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)[9] | Independent dual Z lead-screw motors[8] |
| 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][5] | 600 mm/s, worded by QIDI as maximum tool-head speed (manufacturer claim, not a sustained printing speed)[2][8] |
| Recommended/typical print speed | 250 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][5][6] | <=20,000 mm/s2 (manufacturer claim)[2][8] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[9] | Direct-drive extruder with hardened steel gears[2][8] |
| 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] | Tri-metal hotend with a ceramic heater plate and a bimetal nozzle, 0.4 mm standard[2][8] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | <=350 °C claimed. No firmware max_temp verified for this model[2][8] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature[1] | <=120 °C claimed. No firmware limit verified for this model[2][8] |
| 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[9] | Double-sided textured PEI plate on an aluminium substrate bed[2][8] |
| 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] | Automatic levelling; QIDI markets it as "hands-free automatic levelling" with dual sensors, without naming the probe technology[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted; power-loss resume printing supported[1] | Filament run-out sensor fitted; QIDI also lists filament tangle detection without describing the mechanism[8] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Auxiliary part-cooling fan plus a chamber circulation fan (fan count and duct design not published)[8] |
| 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] | 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][9] | 100-240 VAC, 50/60 Hz[8] |
| Total rated power draw | 310 W rated power, 24 V output[9] | 350 W plus 300 W for chamber heating (rated)[2][8] |
| 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] | Klipper, running on a 64-bit processor per QIDI. Exact fork and version not published on the product page[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[9] | 4.3-inch touchscreen, 272 x 480[2][8] |
| 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-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][5][6] | Wi-Fi 6 (QIDI states "150M 2.4G") and USB 2.0. No Ethernet listed for this model[2][8] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in camera, up to 1080p, timelapse supported. Framerate not published[2][8] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Ships fully assembled[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery listed as a feature; mechanism not published[8] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA, Nylon[1] | QIDI lists compatibility with common filaments; storage 32 GB eMMC. No per-material list published on the current page beyond the general claim[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[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[11] | 1-year coverage, 14-day no-reason return, lifetime tech guidance (QIDI's standard terms as shown on its store)[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.
