Creality K2 Plus vs UltiMaker Factor 4 — documented properties and sources
PropertyCreality K2 PlusCOREXYUltiMaker Factor 4INDUSTRIAL
Identity
BrandCrealityUltiMaker
ClassCOREXYINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2 Plus[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)$999.00 on store.creality.com, Aug 2026[3]Not documented
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]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 usable350 x 350 x 350 mm[1]330 x 240 x 300 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)495 x 515 x 640 mm[1]Not documented
Net weight (kg)35 kg[1]Not documented
Enclosure: open / enclosed; panel material; door/lidEnclosed with chamber temperature control up to 60 C and two air filters[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?)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
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max printing speed (manufacturer claim)[1]Not documented
Max acceleration (claimed, mm/s²)30000 mm/s2 max acceleration (manufacturer claim) - 50% above the rest of the K2 family[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive with a 0.4 mm hardened "unicorn" quick-swap nozzle[4]Direct-drive dual extrusion[2]
Filament diameterNot documented2.85 mm[2]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)350 C claimed max nozzle temperature[1]340 °C maximum with the high-temperature print core (manufacturer claim)[2]
Heater cartridge power (W)100 W rated hotend power[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]Not documented
Bed surface (material, texture, coating), single/double-sidedCoated steel flex plate, heated, removable[4]Not documented
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]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted[4]Not documented
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 designTwo auxiliary cooling fans and two air filters[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[5][6][1]Not documented
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch touchscreen[1]Not documented
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]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi (2.4 and 5 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 1080p 30 fps plus the nozzle AI camera[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[5][6]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[7]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]
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[4]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[4]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.
