|---|---|---|
| Identity | ||
| Brand | Creality | ELEGOO |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2 Plus[1] | ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[2] |
| Release date (announcement and actual shipping) | Not documented | Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[3] |
| Street price (USD; dated snapshot per entry) | $999.00 on store.creality.com, Aug 2026[4] | $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) | Largest and only fully specified K2. It is the only one with a 350 C nozzle, a 120 C bed, 30000 mm/s2 acceleration, step-servo motors on Z as well as X/Y, automatically adjusted belt tension, two auxiliary cooling fans, two air filters, a 1080p chamber camera, dual-band Wi-Fi and a 4.3-inch screen. Its "smart auto levelling" is listed as arriving via firmware update rather than shipping enabled, unlike the K2 and K2 Pro. A separate K2 SE model also exists[1] | 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][5][6] |
| Market position: superseded? successor announced? | Not documented | 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] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 350 x 350 x 350 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) | 495 x 515 x 640 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) | 35 kg[1] | 8.3 kg net, 10.6 kg gross[2] |
| Frame construction & material | Not documented | CNC-machined aluminium extrusion frame[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with chamber temperature control up to 60 C and two air filters[1] | Open frame, no enclosure[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 60 C max chamber temperature (manufacturer figure)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - Creality groups the K2 series with its CoreXY flagships and quotes 600 mm/s with step-servo motors on the X and Y axes[1] | Cartesian i3 bed-slinger[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Two lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[8] |
| Belts (type, width, e.g. Gates?) | Automatically adjusted belt tension - the K2 and K2 Pro are tensioned by hand[1] | Not documented |
| Stepper motors (frame size, step angle, brand if known) | Step-servo motors on the X, Y and Z axes and the extruder[1] | Not documented |
| 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[8] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s max printing speed (manufacturer claim)[1] | 500 mm/s max toolhead speed (manufacturer claim); the Neptune 4 Plus page for the same family states a recommended 250 mm/s[2][5] |
| Recommended/typical print speed | Not documented | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[8] |
| Max acceleration (claimed, mm/s²) | 30000 mm/s2 max acceleration (manufacturer claim) - 50% above the rest of the K2 family[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][5][6] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with a 0.4 mm hardened "unicorn" quick-swap nozzle[9] | Dual-gear direct extruder with 2 fans[8] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Brass nozzle, 0.4 mm, with a copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[8] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature[1] | 300 C claimed max nozzle temperature[2] |
| Heater cartridge power (W) | 100 W rated hotend power[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 110 C max heated bed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Coated steel flex plate, heated, removable[9] | PEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[8] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Smart auto levelling listed as "Available via Firmware Update" rather than shipping enabled; automatic flow-rate calibration via the nozzle AI camera[1] | Manual levelling combined with 121-point auto-levelling; no full-auto calibration on this model[8] |
| 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 design | Two auxiliary cooling fans and two air filters[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | ELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU published[8] |
| Input voltage (110/220 V, switch or auto) | Not documented | 115/230 V, 50/60 Hz on the product page; ELEGOO's compare page gives 110-120 / 220-240 VAC 50/60 Hz[2][8] |
| Total rated power draw | Not documented | 310 W rated power, 24 V output[8] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Creality OS, a Klipper derivative. Creality publishes the K2 firmware source as CrealityOfficial/K2_Series_Klipper on GitHub under GPL-3.0, last pushed March 2026[10][11][1] | Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 series, rather than the ELEGOO OS branding used on the Centauri machines)[8][12] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch touchscreen[1] | 4.3-inch colour capacitive touch screen[8] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touch UI with a built-in RFID reader; Creality notes the K2 Plus has no alarm sounds, which the K2 and K2 Pro do have[1] | Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[8] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi (2.4 and 5 GHz), RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[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][5][6] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | One chamber camera at 1080p 30 fps plus the nozzle AI camera[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, PET, ABS, ASA, PLA-CF, PA-CF, PPA-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 publishes the K2-series firmware as CrealityOfficial/K2_Series_Klipper (GPL-3.0); upstream Klipper ships the verify_heater thermal-runaway check, but whether the stock configuration enables it was not checked here[10][11] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | 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[8] |
| 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[13] | 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[14] |
| Independently Measured Performance | ||
| Benchmark print times (source + settings) | Benchy in 15 minutes 56 seconds - independently measured by Tom's Hardware, which noted visible layer lines and slightly droopy overhangs at that speed[9] | Not documented |
| 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.
