Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 Plus[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 20 September 2023 (Shopify publish date), the same date as the Neptune 4 Max[3][4]Not stated on QIDI's own product page; the page now carries a discontinuation notice instead of a launch date (checked Aug 2026)[2][5]
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[3][6][4]$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][5]
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]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][5]
Market position: superseded? successor announced?Not documentedDiscontinued and out of production; QIDI states spare parts and support for existing owners remain available. Replaced by the Q2[2][5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable320 x 320 x 385 mm; printing platform 330 x 330 mm[1]245 x 245 x 240 mm advertised (QIDI). No independently measured usable envelope found[2][10]
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]477 x 467 x 489 mm machine dimensions (QIDI)[2][10]
Net weight (kg)14.4 kg net, 16.65 kg gross[1]17 kg net, 20.3 kg gross (QIDI). 3DJake lists the 20.3 kg figure as gross weight[2][10]
Frame construction & materialCNC-machined aluminium extrusion frame (Neptune 4 family)[7]Metal CoreXY motion frame with panelled enclosure; QIDI publishes no frame-material breakdown for this model[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed with independent chamber heating to 60 °C; QIDI does not publish the panel materials for this model[2][10]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented60 °C, actively heated (manufacturer claim — this is a heater setpoint, not a measured passive figure)[2][10]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]CoreXY[10]
X-axis guide type (rods / linear rails / V-wheels; size)Not documented10 mm linear steel rods with automatically tensioned belt (manufacturer description)[10]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo lead screws with two tie rods[1]Independent dual Z lead-screw motors[10]
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]600 mm/s, worded by QIDI as maximum tool-head speed (manufacturer claim, not a sustained printing speed)[2][10]
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]<=20,000 mm/s2 (manufacturer claim)[2][10]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[1][9]Direct-drive extruder with hardened steel gears[2][10]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, with a titanium-alloy heat break[1]Tri-metal hotend with a ceramic heater plate and a bimetal nozzle, 0.4 mm standard[2][10]
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][10]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient[1]<=120 °C claimed. No firmware limit verified for this model[2][10]
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]Double-sided textured PEI plate on an aluminium substrate bed[2][10]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Manual levelling combined with 121-point auto-levelling[1]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 run-out sensor and power-loss recovery; no camera, no clog detection, no auto filament unloading[1]Filament run-out sensor fitted; QIDI also lists filament tangle detection without describing the mechanism[10]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedAuxiliary part-cooling fan plus a chamber circulation fan (fan count and duct design not published)[10]
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

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]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[1]4.3-inch touchscreen, 272 x 480[2][10]
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 6 (QIDI states "150M 2.4G") and USB 2.0. No Ethernet listed for this model[2][10]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedBuilt-in camera, up to 1080p, timelapse supported. Framerate not published[2][10]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedShips fully assembled[2]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery listed as a feature; mechanism not published[10]
Materials Support
Officially supported filament listPLA, 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 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]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.
