Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K1 Max[1]ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[2]
Release date (announcement and actual shipping)Not documentedListed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[3]
Street price (USD; dated snapshot per entry)$549.00 on store.creality.com, Aug 2026. Creality's comparison page shows $799 against a struck-through $899 on the same day[4][1]$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]
Variants & sibling models — and how to tell them apart (spec-contamination risk)The large K1. Build volume 300 x 300 x 300 mm and footprint 435 x 462 x 526 mm, both much larger than the K1/K1C's 220 mm cube and 355 mm-wide body; rated power is 1000 W against 350 W; it is the only K1 with RJ45 Ethernet. Its hotend is the older metal + PTFE-tube type with a copper nozzle, annotated by Creality as "Changing to All-metal Soon" and "Copper Nozzle Changing to Steel-tipped Nozzle Integrated with Heatbreak Soon", so hotend type varies by production run - do not assume it matches the K1C[1][5]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][2][6][7]
Market position: superseded? successor announced?Not documentedStill 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]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable300 x 300 x 300 mm[1]225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)435 x 462 x 526 mm[1]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[2]
Net weight (kg)18 kg (Tom's Hardware measurement)[9]8.3 kg net, 10.6 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed with passive chamber heating only - Creality's comparison table lists "Passive Heating" for the K1, K1C and K1 Max and no chamber heating for the K1 SE[1]Open frame, no enclosure[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (Creality's own K1-series comparison table)[1]Cartesian i3 bed-slinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedTwo lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[10]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documented"Silent Drive (All Axes)" is all ELEGOO publishes; no driver part number is given[10]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max printing speed (manufacturer claim). Creality's own footnote says the 600 mm/s figure was achieved in Creality Lab and that the typical speed is 300 mm/s[1][5]500 mm/s max toolhead speed (manufacturer claim); the Neptune 4 Plus page for the same family states a recommended 250 mm/s[2][6]
Recommended/typical print speed300 mm/s typical printing speed with 12000 mm/s2 typical acceleration, stated by Creality alongside the 600 mm/s headline[1]250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[10]
Max acceleration (claimed, mm/s²)20000 mm/s2 max acceleration (manufacturer claim)[1]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[2][6][7]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct-drive extruder[1]Dual-gear direct extruder with 2 fans[10]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Metal hotend with a PTFE tube and a copper nozzle, both annotated by Creality as changing to all-metal and to a steel-tipped integrated nozzle "soon"[1]Brass nozzle, 0.4 mm, with a copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[10]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature[1]110 C max heated bed temperature[2]
Bed surface (material, texture, coating), single/double-sidedSmooth PEI steel flex plate, heated[9]PEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[10]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic bed levelling assisted by a lidar sensor - Tom's Hardware records "Automatic + LIDAR", a feature the K1 and K1C do not have[9][11][12]Manual levelling combined with 121-point auto-levelling; no full-auto calibration on this model[10]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted[9]Filament detection fitted; power-loss resume printing supported[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designClosed-loop part-cooling fan and PWM hotend fan, both annotated as changing to dynamically balanced versions; activated-carbon air filter fitted[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU published[10]
Input voltage (110/220 V, switch or auto)Not documented115/230 V, 50/60 Hz on the product page; ELEGOO's compare page gives 110-120 / 220-240 VAC 50/60 Hz[2][10]
Total rated power draw1000 W rated power - nearly three times the K1/K1C figure[1]310 W rated power, 24 V output[10]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Creality OS, a Klipper derivative published as CrealityOfficial/K1_Series_Klipper on GitHub (GPL-3.0); the printhead front cover is listed as an open-source part[13][14][1]Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 series, rather than the ELEGOO OS branding used on the Centauri machines)[10][15]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch 800x480 colour touchscreen[1]4.3-inch colour capacitive touch screen[10]
On-device UI capabilities (model preview, per-object controls, etc.)Colour touch UI with remote monitoring, time-lapse, build-surface detection and failure detection all included[1]Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[10]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi plus RJ45 Ethernet - the only K1-series machine with a wired network port; 8 GB storage[1]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)[2][6][7]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)1080p AI camera fitted as standard with foreign-object detection[1]Not documented
Materials Support
Officially supported filament listABS, PLA, PETG, PET, TPU, PA, ASA, PC, PLA-CF, PA-CF, PET-CF[1]PLA, TPU, PETG, ABS, ASA, Nylon[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not verified directly. Creality's published firmware for the K1 series (CrealityOfficial/K1_Series_Klipper, GPL-3.0) is described by Creality itself as a clone of upstream Klipper, and upstream Klipper ships the verify_heater thermal-runaway check; whether Creality's stock printer.cfg enables it, and with what thresholds, was not checked here[13][14]Not documented
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating 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[10]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Creality's US store states "Up to 12-Month Warranty", a 14-day return and refund window and "Lifetime Customer Support" on its printer product pages. The "up to" wording means the term is not uniform across parts[16]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[17]
Independently Measured Performance
Review scores from major outlets (list outlet + score + date)Tom's Hardware rating 4.5 out of 5 in the page's structured data[9]Not documented

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.
