Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2[1]Original Prusa MINI+ Semi-assembled 3D Printer[2]
Street price (USD; dated snapshot per entry)Not documented$508.33 on prusa3d.com, Aug 2026[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 semi-assembled and, historically, as a kit; also offered in an Enclosure Bundle. Distinguish from the larger i3-family machines - the MINI+ is Bowden-fed with 2209 drivers, a 280 C nozzle ceiling and a 100 C bed, all lower than the MK3S+/MK4S. Note that Prusa's own MINI+ page carries an "Awards & Press Reviews" paragraph that is entirely about the MK3S, not the MINI+[2][4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable260 x 260 x 260 mm[1]180 x 180 x 180 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)404 x 436 x 545 mm[1]380 x 330 x 380 mm (X x Y x Z), stated without the spool holder and external PSU - the external PSU brick needs additional desk space[2]
Net weight (kg)18.3 kg[1]4.5 kg without spool holder and external PSU[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]Open frame; sold with an optional Enclosure bundle[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]Not documented
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
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic 2209 silent stepper drivers, with sensorless homing on the X and Y axes[2]
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
Extruder
Type (direct drive / bowden) & design nameNot documentedBowden extruder with 3:1 gearing - the only current Prusa FFF machine that is not direct drive[2]
Gear ratio & drive gear materialNot documented3:1 extruder gearing[2]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]280 C claimed max nozzle temperature - lower than the 290-300 C of the i3-family machines[2]
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]100 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedRemovable magnetic steel sheets in several surface finishes; heatbed with cold-corner compensation[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]SuperPINDA inductive probe with no temperature drift, driving automatic mesh bed levelling[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designOne auxiliary cooling fan and one air filter[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit board of Prusa's Buddy family; the MINI/MINI+ is covered by the same Prusa-Firmware-Buddy source tree as the MK4, XL and CORE One. The exact board revision is not given on the product page[2][5]
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[6][7][1]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[5][8]
Connectivity, UI & Camera
Display: size, type, touch?4-inch touchscreen[1]2.8-inch 65k-colour graphic screen with G-code preview[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touch UI with alarm sounds; no built-in RFID reader[1]On-device colour UI with G-code preview; remote print management through Prusa Connect[2]
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]USB port, RJ-45 Ethernet, optional ESP Wi-Fi module (sold separately); compatible with Prusa Connect[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 printNot documentedSemi-assembled: Prusa ships it in a small number of pre-built sections; also historically sold as a full kit[2]
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]PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, Woodfill and other filled materials (Prusa's own list; the 100 C bed and open frame are the practical limit for ABS/ASA)[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[6][7]Three thermistors and fan RPM sensors are fitted, and the firmware is open-source and auditable (Prusa-Firmware-Buddy); Prusa does not describe the thermal-runaway implementation on the product page[2][5]
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]2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[10][8]

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.
