ClassCOREXYINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2[1]UltiMaker S8 3D Printer[2][3]
Release date (announcement and actual shipping)Not documentedLaunched March 2025; the technical-specification and pricing announcement is dated 14 March 2025[3]
Street price (USD; dated snapshot per entry)Not documentedStarting at $8,999 at MatterHackers, in stock, checked Aug 2026. The launch announcement quoted approximately $9,000[2][3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Smallest of three K2 machines that share a product page. K2: 260 mm cube, no chamber heating, 100 C bed, 300 C nozzle, 8 GB storage, one air filter, one auxiliary cooling fan, 720p camera, no RFID reader, no Ethernet. K2 Pro: 300 mm cube, 60 C chamber, 110 C bed, RFID, Ethernet, 32 GB. K2 Plus: 350 mm cube, 350 C nozzle, 120 C bed, 30000 mm/s2, dual air filters, auto belt tensioning, 1080p camera, dual-band Wi-Fi. A K2 SE also exists as a separate model[1]Sold as printer-only or as a Pro Bundle. The bundle is not a trim level but a different machine footprint and weight: 495 x 500 x 1210.5 mm and 47.7 kg with the 6-spool Material Station, versus 495 x 585 x 800.5 mm and 30 kg for the printer alone. Print cores AA+ 0.40 x2 are included; BB, CC+ and DD 0.40 are separate purchases[2][3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable260 x 260 x 260 mm[1]330 x 240 x 300 mm[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)404 x 436 x 545 mm[1]495 x 585 x 800.5 mm printer only; 495 x 500 x 1210.5 mm as the Pro Bundle[2][3]
Net weight (kg)18.3 kg[1]30 kg printer only; 47.7 kg as the Pro Bundle[2][3]
Frame construction & materialNot documentedFully assembled, made in Europe[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed, but with no chamber temperature control - Creality's table gives a max chamber temperature for the K2 Pro and K2 Plus and a dash for the K2. One air filter fitted[1]Enclosed, with an Air Manager UltiMaker says removes up to 95% of ultrafine particles[2][3]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documentedBuild-volume temperature under 50 °C with open-loop control (manufacturer figure)[2][3]
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]Dual-extrusion print head with auto nozzle-lifting, flood detection and inductive probing. UltiMaker's Cheetah motion planner uses third-order continuous motion with corner blending[2][3]
Belts (type, width, e.g. Gates?)Manual belt tensioning (the K2 Plus is auto-adjusted)[1]Not documented
Stepper motors (frame size, step angle, brand if known)Step-servo motors on the X and Y axes and the extruder (the K2 Plus adds them on Z)[1]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max printing speed (manufacturer claim)[1]Up to 500 mm/s in XY (manufacturer claim)[2][3]
Max acceleration (claimed, mm/s²)20000 mm/s2 max acceleration (manufacturer claim)[1]Up to 50,000 mm/s2 (manufacturer claim)[2][3]
Jerk / square-corner-velocity setting (exact value)Not documentedJerk up to 100,000,000 mm/s3 (manufacturer claim)[2][3]
Max volumetric flow claimed (mm³/s)Not documentedUp to 35 mm3/s extrusion flow (manufacturer claim)[2][3]
Extruder
Type (direct drive / bowden) & design nameNot documentedDual gripper feeder with tension adjustment, release function and filament feed-rate control[2][3]
Filament diameterNot documented2.85 mm[2][3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedSwappable print cores; AA+ 0.40 x2 included, BB 0.40 / CC+ 0.40 / DD 0.40 sold separately[2][3]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]Up to 340 °C (manufacturer claim)[2][3]
Heater cartridge power (W)70 W rated hotend power[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature - the lowest in the K2 family[1]Up to 120 °C on a flexible PEI plate (manufacturer claim)[2][3]
Bed surface (material, texture, coating), single/double-sidedNot documentedFlexible PEI plate[2][3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Smart auto levelling fitted; unlike the K2 Pro and Plus there is no nozzle AI camera, so there is no automatic flow-rate calibration[1]Inductive probing, integrated into the print head[2][3]
Filament Handling & Detection
Spool holder location & max spool size; drybox compatibilityNot documentedDual spool holder with NFC recognition on the printer; the Pro Bundle substitutes a 6-spool Material Station with NFC and a dual-geared abrasion-resistant feeder[2][3]
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 documentedAir Manager, which UltiMaker says removes up to 95% of ultrafine particles[2][3]
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 published; print preparation is UltiMaker Cura 5.10 or newer, fleet management via UltiMaker Digital Factory[2][3]
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; no built-in RFID reader[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi 2.4 GHz, USB drive and a Creality 485 port; no Ethernet. 8 GB eMMC storage[1]Wi-Fi 2.4 and 5 GHz (802.11a/b/g/n/ac), Gigabit Ethernet, USB 2.0[2][3]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)One chamber camera, 720p at 30 fps[1]Full HD HDR camera[2][3]
Materials Support
Officially supported filament listPLA, PETG, PET, ABS, PLA-CF - a shorter list than the K2 Pro and Plus, which add ASA, PA-CF and PPA-CF[1]UltiMaker cites 301+ compatible materials including its own PLA, PETG, ABS, CPE, CPE+, PC, TPU and PET-CF, plus third-party grades[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
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedUnder 50 dBA operating sound, manufacturer figure. No independent measurement; distance and method not stated[2][3]
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]12 months, extendable to 5 years with an UltiMakerCare plan[2][3]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedDimensional accuracy +/-0.15 mm +/-0.15% of feature nominal length (manufacturer specification, not an independent measurement)[2][3]

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.
