What the Creality K3 is
The K3 is Creality’s four nozzle multicolour printer, opened for preorder on its own US store at 849 dollars with an estimated ship date of 2 November. There is one version at that price, with no bundle and no struck through comparison figure, both read off Creality’s store on 16 October 2026. It is an enclosed CoreXY machine with a 260 by 260 by 260 mm build volume and a stated top speed of 500 mm per second.
Four nozzles instead of one
The reason this machine exists is purge waste. On a single nozzle printer every colour or material change pushes the old filament out as waste, and on a model with hundreds of changes that is the largest running cost in colour printing. The K3 keeps four filaments loaded in independent channels and swaps the whole nozzle assembly instead of flushing one, which Creality puts at about five seconds with nothing purged to make the change. It calls the mechanism KliTek.
Creality’s own lab figure for this is one Wolf Bust model with 1,182 nozzle changes: 231 grams on the K3 with a prime tower, against 2,645 grams on a single nozzle printer with prime and purges. That is Creality’s measurement rather than ours, and nobody outside the company has reproduced it yet, because the machine has not shipped.
Nozzle sizes and colour blending
The four nozzles come in 0.2, 0.4, 0.6 and 0.8 mm and can be mixed inside a single print, which Creality notes needs configuring. The use it suggests is a fine 0.4 mm nozzle on the outer walls with a high flow 0.8 mm nozzle on infill. Nozzle assemblies swap by USB C.
Colour works differently from a spool based system too. Rather than adding filaments for more colours, the K3 layers four CMYK filaments at controlled thicknesses and lets light pass through translucent material so the colours blend physically.
What is not yet known
Creality publishes no hot end or bed temperature in the K3 specification table, so neither is listed here. Every performance figure above is Creality’s own, several of them footnoted to Creality Lab, and most carry a condition: the filament saving is quoted for setups of four colours or fewer, and the TPU flow rate needs accessories sold separately. Planet 3DP has not tested a K3. The first independent numbers should arrive once machines ship in November.
