| Property | Creality K2COREXY | Positron V3.2COREXY |
|---|---|---|
| Identity | ||
| Brand | Creality | Positron3D |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2[1] | LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[2] |
| 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] | The defining trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 180 x 180 x 165 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 404 x 436 x 545 mm[1] | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[2] |
| Net weight (kg) | 18.3 kg[1] | 3 kg net; 5.5 kg with the hard case[2] |
| Frame construction & material | Not documented | Folding frame designed to fit in a filament box; supplied with a black hard case[2] |
| Enclosure: open / enclosed; panel material; door/lid | 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[1] | Open frame[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] | CoreXY, inverted — the machine prints upside down[2] |
| 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] | 250 mm/s maximum print speed (manufacturer claim)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | 8,000 mm/s2 (manufacturer claim)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Bowden-style, single extrusion[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | PS plated-copper nozzle, 0.4 mm[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 260 °C maximum (manufacturer claim)[2] |
| Heater cartridge power (W) | 70 W rated hotend power[1] | Not documented |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Plated copper[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature - the lowest in the K2 family[1] | 85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Heated removable ITO glass bed[2] |
| 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] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One auxiliary cooling fan and one air filter[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | LDO Positron mainboard[2] |
| PSU (brand, wattage, rail voltage) | Not documented | DC 24 V, 200 W[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[3][4][1] | Klipper[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4-inch touchscreen[1] | 3.5-inch LCD touchscreen[2] |
| 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-drive | Wi-Fi 2.4 GHz, USB drive and a Creality 485 port; no Ethernet. 8 GB eMMC storage[1] | Wi-Fi, USB, Ethernet[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | One chamber camera, 720p at 30 fps[1] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit, manufactured in China[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, PET, ABS, PLA-CF - a shorter list than the K2 Pro and Plus, which add ASA, PA-CF and PPA-CF[1] | PLA and PETG only, per the manufacturer[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[3][4] | 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[5] | 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.
