| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K1 (store title "Creality K1 Speedy 3D Printer")[1][2] | Creality K2[3] |
| Street price (USD; dated snapshot per entry) | $299.00 on store.creality.com, Aug 2026. Creality's own K1-series comparison page shows $389 against a struck-through $599 on the same day[2][1] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Base model of the K1 family. The differences that matter are in the hotend: the K1 uses a metal + PTFE-tube hotend with a copper nozzle, while the K1C is all-metal with a steel-tipped nozzle integrated with the heatbreak and adds an air filter and a 1080p AI camera. Creality's own comparison table annotates the K1 hotend "Changing to All-metal Soon", so the hotend on a given unit depends on when it was built - check before buying. The K1 Max is the 300 mm version with 1000 W rated power and Ethernet; the K1 SE has a PA+30%GF hotend and an epoxy plate[1][4] | 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[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 220 x 220 x 250 mm[1] | 260 x 260 x 260 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 355 x 355 x 480 mm[1] | 404 x 436 x 545 mm[3] |
| Net weight (kg) | 12.5 kg (Tom's Hardware measurement)[5] | 18.3 kg[3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with passive chamber heating only - Creality's comparison table lists "Passive Heating" for the K1, K1C and K1 Max and no chamber heating for the K1 SE[1] | Enclosed, 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[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (Creality's own K1-series comparison table)[1] | 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[3] |
| Belts (type, width, e.g. Gates?) | Not documented | Manual belt tensioning (the K2 Plus is auto-adjusted)[3] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | Step-servo motors on the X and Y axes and the extruder (the K2 Plus adds them on Z)[3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s max printing speed (manufacturer claim). Creality's own footnote says the 600 mm/s figure was achieved in Creality Lab and that the typical speed is 300 mm/s[1][4] | 600 mm/s max printing speed (manufacturer claim)[3] |
| Recommended/typical print speed | 300 mm/s typical printing speed with 12000 mm/s2 typical acceleration, stated by Creality alongside the 600 mm/s headline[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | 20000 mm/s2 max acceleration (manufacturer claim)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct-drive extruder[1] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Metal hotend with a PTFE (Teflon) tube in the filament path and a copper nozzle. Creality's own comparison table adds "(Changing to All-metal Soon)", so this is a moving target across production runs[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 300 C claimed max nozzle temperature[3] |
| Heater cartridge power (W) | Not documented | 70 W rated hotend power[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature[1] | 100 C max heatbed temperature - the lowest in the K2 family[3] |
| Bed surface (material, texture, coating), single/double-sided | Coated steel flex plate, heated, removable[5] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic bed levelling (Tom's Hardware); unlike the K1 Max there is no lidar[5][6] | Smart auto levelling fitted; unlike the K2 Pro and Plus there is no nozzle AI camera, so there is no automatic flow-rate calibration[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted[5] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Closed-loop part-cooling fan; PWM hotend cooling fan[1] | One auxiliary cooling fan and one air filter[3] |
| Electronics & Power | ||
| Total rated power draw | 350 W rated power[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Creality OS, a Klipper derivative. Creality publishes the source as CrealityOfficial/K1_Series_Klipper on GitHub, whose own description is "clone from https://github.com/Klipper3d/klipper/", GPL-3.0, last pushed December 2025[7][8][1] | 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[9][8][3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch 800x480 colour touchscreen[1] | 4-inch touchscreen[3] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; remote monitoring, time-lapse, failure detection and build-surface detection are all optional on the K1 because they depend on the optional AI camera[1] | Touch UI with alarm sounds; no built-in RFID reader[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi only - no Ethernet (the K1 Max adds RJ45); 8 GB of on-board storage[1] | Wi-Fi 2.4 GHz, USB drive and a Creality 485 port; no Ethernet. 8 GB eMMC storage[3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera optional, not fitted as standard - unlike the K1C and K1 Max, which include a 1080p camera[1] | One chamber camera, 720p at 30 fps[3] |
| Materials Support | ||
| Officially supported filament list | Hyper PLA, PLA, PETG, TPU, ABS - a notably shorter list than the K1C, because of the PTFE-lined hotend[1] | PLA, PETG, PET, ABS, PLA-CF - a shorter list than the K2 Pro and Plus, which add ASA, PA-CF and PPA-CF[3] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not verified directly. Creality's published firmware for the K1 series (CrealityOfficial/K1_Series_Klipper, GPL-3.0) is described by Creality itself as a clone of upstream Klipper, and upstream Klipper ships the verify_heater thermal-runaway check; whether Creality's stock printer.cfg enables it, and with what thresholds, was not checked here[7][8] | 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[9][8] |
| 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[2] | 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[2] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware rating 4 out of 5 in the page's structured data - the lowest of the K1 family, where the K1C and K1 Max both score 4.5[5][6][10] | 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.
