Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 Plus[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 20 September 2023 (Shopify publish date), the same date as the Neptune 4 Max[4][5]Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[6]
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[4][7][5]$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)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][8][9][10]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Market position: superseded?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?Not documentedSuperseded 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[11][12]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable320 x 320 x 385 mm; printing platform 330 x 330 mm[1]305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][6]
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]505 x 487 x 550 mm[6]
Net weight (kg)14.4 kg net, 16.65 kg gross[1]32 kg gross (3DJake). QIDI does not publish a net weight on the product page[6]
Frame construction & materialCNC-machined aluminium extrusion frame (Neptune 4 family)[8]Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][6]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[2][6]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]CoreXY[6]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo lead screws with two tie rods[1]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; 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 (manufacturer claim, tool-head maximum)[6]
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)[6]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[1][10]Direct drive with hardened steel dual gears, 1.75 mm filament[2][6]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, with a titanium-alloy heat break[1]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][6]
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][6]
Heater cartridge power (W)Not documented80 W hotend heater (manufacturer figure)[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient[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][6]
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]6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][6]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Manual levelling combined with 121-point auto-levelling[1]Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][6]
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, plus a filament cutter and filament tangle detection (tangle mechanism not described)[6]
Multi-material/multi-color capability or official upgrade pathNot documentedQIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[2][3]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedAuxiliary part-cooling fan plus a chamber circulation fan; fan sizes and duct design not published[6]
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
Input voltage (110/220 V, switch or auto)Not documented100-240 VAC, 50/60 Hz[6]
Total rated power draw320 W rated power; 24 V output; 110-120 V / 220-240 V input[1]450 W plus 400 W for chamber heating (rated)[6]
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][10]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[1]5-inch touchscreen, 800 x 480[2][6]
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 2.4 GHz, Ethernet, USB[2][6]
Cloud service & phone app; LAN-only mode possible?Not documentedMobile and computer control, remote cloud or LAN-only operation[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedBuilt-in low-frame-rate camera, up to 1080p, timelapse supported[2][6]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedQIDI 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 documentedPower-loss recovery listed; mechanism not published[6]
Materials Support
Officially supported filament listPLA, 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][6]
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[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.
