Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2 Pro[1]ELEGOO Neptune 4 Max[2]
Release date (announcement and actual shipping)Not documentedListed on the ELEGOO US store from 20 September 2023 (Shopify publish date)[3]
Street price (USD; dated snapshot per entry)$599.00 and $799.00 are the two variant prices listed on the Creality US store K2 Pro Combo page, Aug 2026 - the combo includes a CFS unit, so neither figure is a bare-printer price[4]$389.00 on us.elegoo.com, Aug 2026, against a compare-at price of $559.99; Ribbon-Cable and Type-C printhead variants are the same price[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Between the K2 (260 mm cube, no chamber heating, 100 C bed, 8 GB) and the K2 Plus (350 mm cube, 350 C nozzle, 120 C bed, 30000 mm/s2, dual filters, auto belt tensioning, 1080p camera, dual-band Wi-Fi). The K2 Pro shares the K2's 300 C nozzle and 70 W hotend but gets the chamber heater, RFID reader, Ethernet and 32 GB storage[1]Largest Neptune 4. The trade-off against the smaller models is easy to miss: the bed only reaches 85 C (against 100 C on the Plus and 110 C on the base Neptune 4) and acceleration is capped at 8000 mm/s2 (against 12000 and 20000), because of the mass of a 430 x 430 mm moving bed. Two printhead variants, Ribbon-Cable and Type-C, are sold under one SKU[2][5][6][3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable300 x 300 x 300 mm[1]420 x 420 x 480 mm; printing platform 430 x 430 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)445 x 477 x 573 mm[1]658 x 632 x 740 mm; ELEGOO's maximum size for machine activity is 658 x 950 x 960 mm including rack and tray - allow nearly a metre of depth and height[2]
Net weight (kg)23.7 kg[1]18.1 kg net, 21.8 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed with chamber temperature control up to 60 C; one air filter[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-backlashNot documentedTwo lead screws with two tie rods[7]
Belts (type, width, e.g. Gates?)Manual belt tensioning[1]Not documented
Stepper motors (frame size, step angle, brand if known)Step-servo motors on the X and Y axes and the extruder[1]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documented"Silent Drive (All Axes)"; no driver part number published[7]
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)[2]
Recommended/typical print speedNot documented250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[7]
Max acceleration (claimed, mm/s²)20000 mm/s2 max acceleration (manufacturer claim)[1]8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[2]
Extruder
Type (direct drive / bowden) & design nameNot documentedDual-gear direct extruder with 2 fans[7]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedBrass nozzle, 0.4 mm, with a titanium-alloy heat break[7]
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]
Heater cartridge power (W)70 W rated hotend power[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heatbed temperature[1]85 C max heated bed temperature at 25 C ambient - well below the 100-110 C of the smaller Neptunes, which limits ABS/ASA work despite them being on the compatibility list[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedPEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[7]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Smart auto levelling, plus automatic flow-rate calibration using a nozzle AI camera[1]Manual levelling combined with 121-point auto-levelling[7]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament detection and power-loss resume printing[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designOne auxiliary cooling fan and one air filter[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documented"Klipper High-Speed Quiet Motherboard" is all ELEGOO publishes[7]

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[8][9][1]Klipper[7]

WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi 2.4 GHz, RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[1]Wi-Fi, USB and WLAN file transfer[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)One chamber camera at 720p 30 fps, plus a separate nozzle AI camera used for flow calibration[1]Not documented
Materials Support
Officially supported filament listPLA, PETG, PET, ABS, ASA, PLA-CF, PA-CF, PPA-CF[1]PLA, TPU, PETG, ABS, ASA, Nylon - but note the 85 C bed ceiling against ABS and ASA[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[8][9]Not documented
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating sound published as 65 dB or less - a manufacturer figure with no distance or method stated[7]
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[10]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]

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.
