| Property | Creality K2 ProCOREXY | UltiMaker S7INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Creality | UltiMaker |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2 Pro[1] | UltiMaker S7[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] | $5,999.00 for the standard model at 3D Universe, in stock, checked Aug 2026[2] |
| 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] | Same 330 x 240 x 300 mm envelope as the S5 and S8. The S7 is distinguished from the S5 by a PEI-coated flexible build plate (rather than glass) and dual-band Wi-Fi; from the S8 by nozzle temperature (S8 reaches 340 °C) and speed (S8 quotes 500 mm/s and 50,000 mm/s2)[2][4][5] |
| Market position: superseded? successor announced? | Not documented | Superseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[5][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 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] | 495 x 585 x 780 mm with the spool holder[2] |
| Net weight (kg) | 23.7 kg[1] | Not documented |
| Frame construction & material | Not documented | Fully assembled professional chassis[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with chamber temperature control up to 60 C; one air filter[1] | Not documented |
| 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] | Dual-extrusion gantry with auto nozzle-lifting and swappable print cores; kinematic layout not published[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 |
| Max volumetric flow claimed (mm³/s) | Not documented | Build speed under 24 mm3/s (manufacturer figure)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Dual extrusion with swappable print cores[2] |
| Filament diameter | Not documented | 2.85 mm[2] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | Not documented |
| Heater cartridge power (W) | 70 W rated hotend power[1] | Not documented |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm standard; 0.25, 0.6 and 0.8 mm available separately[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heatbed temperature[1] | PEI-coated flexible build plate, 20-140 °C[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | PEI-coated flexible build plate[2] |
| 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 |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One auxiliary cooling fan and one air filter[1] | Not documented |
| 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[7][8][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-drive | Wi-Fi 2.4 GHz, RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[1] | Wi-Fi 2.4 GHz and 5 GHz, LAN, USB[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 list | PLA, PETG, PET, ABS, ASA, PLA-CF, PA-CF, PPA-CF[1] | Not documented |
| 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[7][8] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Under 50 dBA operating sound, manufacturer figure. No independent measurement[2] |
| 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[9] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XYZ resolution 6.9 / 6.9 / 2.5 micron (manufacturer specification)[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.
