Creality K2 Pro vs UltiMaker Factor 4 — documented properties and sources
PropertyCreality K2 ProCOREXYUltiMaker Factor 4INDUSTRIAL
Identity
BrandCrealityUltiMaker
ClassCOREXYINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2 Pro[1]UltiMaker Factor 4[2]
Release date (announcement and actual shipping)Not documentedAnnounced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[2]
Launch MSRP (USD)Not documentedStarting at approximately $20,000[2]
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[3]Not documented
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]Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable300 x 300 x 300 mm[1]330 x 240 x 300 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)445 x 477 x 573 mm[1]Not documented
Net weight (kg)23.7 kg[1]Not documented
Enclosure: open / enclosed; panel material; door/lidEnclosed with chamber temperature control up to 60 C; one air filter[1]Enclosed with actively controlled chamber airflow and a HEPA filter[2]
Passive chamber temperature reached (if enclosed; measured values preferred)60 C max chamber temperature (manufacturer figure)[1]Build volume temperature controlled up to 70 °C with actively controlled chamber airflow (manufacturer specification)[2]
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]Direct-drive dual extrusion; kinematic layout not stated in the source checked[2]
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
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max printing speed (manufacturer claim)[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 max acceleration (manufacturer claim)[1]Not documented
Extruder
Type (direct drive / bowden) & design nameNot documentedDirect-drive dual extrusion[2]
Filament diameterNot documented2.85 mm[2]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]340 °C maximum with the high-temperature print core (manufacturer claim)[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]Not documented
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]Not documented
Filament Handling & Detection
Spool holder location & max spool size; drybox compatibilityNot documentedAutomatic climate-controlled material handling and storage station holding humidity below 15%, storing up to six spools[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designOne auxiliary cooling fan and one air filter[1]Not documented
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documentedHEPA filter[2]
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[4][5][1]Not documented
Connectivity, UI & Camera
Display: size, type, touch?4-inch touchscreen[1]Not documented
On-device UI capabilities (model preview, per-object controls, etc.)Touch UI with alarm sounds and a built-in RFID reader for automatic filament identification (needs Creality RFID filament)[1]Not documented
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]Not documented
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]UltiMaker-branded PPS CF, PLA, Tough PLA, Nylon, PETG, PET CF and PVA, plus validated third-party materials from BASF Forward AM, Kimya, Polymaker, LEHVOSS and Jabil[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[4][5]Not documented
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[6]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedDimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[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.
