What to feed the Creality K1
Built for speed, feed it accordingly
The K1 is Creality's fast machine, and some spools are made for that pace. Hyper PLA (220 °C recommended) is named for this printer's own series, and the new generation of high-speed PETG belongs here too.
The full menu
PLA, PETG, TPU, ABS, and ASA. For ABS and ASA, the 100 °C bed sits at the lower end of their 90-110 °C appetite, so give large parts every advantage: ventilation, still air, patience with the first layer.
TPU at K1 speeds?
No such thing. Flexibles ignore marketing numbers. Print TPU at TPU speeds on any machine, this one included, and it comes out lovely.

The Micro Center house brand. If there's a store near you, it's the cheapest reliable PLA+ you can walk out with today.
