Creality K2 Combo 3D Printer with CFS
Multicolour PLA and PETG printing on a 260 mm build volume
The base K2 printer with one four-spool CFS: a 260 mm cube build volume, a 300C nozzle with a hardened steel tip, a 100C bed, step-servo X, Y and extruder motors and a 720p chamber camera. Creality lists no chamber heating, no Ethernet and 2.4 GHz Wi-Fi only for this model.

Fit and limits
Strengths
- One CFS included, expandable to four units and 16 colours
- Step-servo motors on X, Y and extruder with smart auto levelling
- Hardened steel nozzle tip and 300C cap for PLA-CF
Caveats
- No chamber heating, yet ABS is listed despite a 60C chamber footnote
- Listing says 80 W heater; Creality's table says 70 W for the K2
- 2.4 GHz Wi-Fi only, no Ethernet, and 8 GB of storage
K2, not K2 Pro or K2 Plus: why the name matters
Creality sells three printers under the K2 name and describes them on one page. This listing's model field is K2 Combo, which is the base K2 printer paired with one CFS filament unit. Creality's footnote says the combo version comes with one CFS unit and that additional units are sold separately.
Several headline features on Creality's K2 series page belong only to the bigger models. Active chamber heating to 60 degrees is on the K2 Pro and K2 Plus, and Creality's comparison table shows a dash for the K2's chamber temperature. The nozzle AI camera, the built-in RFID reader, the Ethernet port and 32 GB of storage are also K2 Pro and K2 Plus features.
So read the K2 column, not the series headline. The listing bullets are mostly consistent with that column, but a few details differ, which are covered below. The listing brand field reads Comgrow while the manufacturer field reads Creality 3D; the maker documents we read are Creality's.
The K2 column of Creality's comparison table
Build volume is 260 by 260 by 260 millimetres. Product dimensions are 404 by 436 by 545 millimetres and net weight is 18.3 kilograms. The listing gives 17.24 by 18.58 by 16.7 inches in one field and 20 by 24 by 19 inches in another, with 39.7 pounds, and does not say whether those include the CFS.
Maximum speed is 600 mm/s with 20,000 mm/s squared acceleration, and Creality's footnote gives the typical printing speed for all K2 models as 300 mm/s. Maximum nozzle temperature is 300 degrees Celsius and the heatbed reaches 100 degrees. The chamber camera is 720p at 30 frames per second and the touchscreen is 4 inches.
Step-servo motors drive the X and Y axes and the extruder, and belt tensioning is manual. There is one auxiliary cooling fan and one air filter, and Creality says its air purifier filters VOCs. Smart auto levelling is listed as yes, and the listing says it probes only the print area.
Filaments: what the printer and the CFS each accept
Creality's table lists compatible filaments for the K2 as PLA, PETG, PET, ABS and PLA-CF, a shorter list than the CFS page gives for the feeder. Creality's footnote says printing ABS, ASA and PPS requires a 60 degree chamber, yet the same page lists ABS for the K2 and gives the K2 no chamber temperature. Ask Creality before planning ABS work on this model.
The CFS has its own limits. Creality's CFS compatibility page gives an accepted spool size of 197 to 202 millimetres in diameter and 42 to 68 millimetres thick, and names PLA, PETG, ABS, PLA-CF, PET, ASA, HIPS, dried PVA and BVOH as compatible. It excludes all TPU and other elastic materials, and PVA or BVOH that has softened from moisture.
The same page warns that harder filaments such as PPA-CF and PPS-CF can break inside the tube, and says not to use deformed or undersized spools. The wiki manual adds a note against cardboard spools with untreated edges or deformation. Creality recommends its own Hyper plastic-spool filaments.
Where the listing and Creality differ
The listing says the 40 cubic millimetre per second hotend is powered by an 80 watt heater. Creality's comparison table lists the K2's rated hotend power as 70 watts, with 100 watts only on the K2 Plus. Creality's footnote says its flow figure was tested with ABS at a 280 degree nozzle, but we did not record a K2 flow figure from Creality, so the 40 mm3/s is the listing's number.
The listing gives acceleration as 20,000 mm/s cubed, while Creality's table gives 20,000 mm/s squared. The listing's three step-servo motors match Creality's footnote for the K2, which puts them on the X and Y axes and the extruder.
The listing's bullets mention a chamber. Creality lists a chamber camera for the K2, but its own table shows no maximum chamber temperature for the K2 and reserves active chamber heating for the K2 Pro and K2 Plus. Do not buy this model expecting a heated chamber.
Connectivity, storage and setup
The K2 connects by 2.4 GHz Wi-Fi, USB drive and Creality's 485 port, which the wiki manual uses to link the CFS. Creality's table lists no RJ45 Ethernet for the K2 and only 2.4 GHz Wi-Fi, where the K2 Plus adds 5 GHz. Storage is 8 GB of eMMC.
Creality says all K2 models can print after unpacking and installing the touchscreen, then following the boot-up guide for automatic levelling and fan calibration. The wiki manual's contents cover removing transport holders and locking screws, fitting the screen, spool holder and PTFE tubes, and connecting the CFS; follow the manual for the order and details.
Printing works through Creality Print over the local network or through the Creality Cloud app, which the wiki manual says binds the printer by QR code. Creality describes the firmware, Creality OS, as offering multi-filament management, root access and an expert mode.
Siting, care and what we did not read
The wiki manual's notes ask for a well-ventilated, cool, dust-free spot away from heat sources and flammable objects and away from vibration. It requires the supplied power cable and a grounded three-prong outlet, and warns not to wear gloves or wraps. Children must be accompanied by an adult at all times near the printer.
The care items in the notes are to clean the extruder with tools while it still has residual heat, rather than touching the nozzle or bed, and to wipe the body and guide rails with a dry cloth after powering off. The manual's specification and maintenance sections are images we did not read.
We did not read a warranty document, and neither the listing nor the pages we read state a K2 warranty term, so ask Creality or the seller before you buy. Creality's claim that the K2 series runs as quietly as typing on a laptop comes with no decibel figure, so we cannot give a noise number.
