PA6 (Nylon 6) on the Creality K1
Yes, with a couple of cautions. Enclosed and quick. Creality sells the K1C when you want carbon fiber.
PA6 (Nylon 6) works on the Creality K1, mind a couple of things
Use the lower end of the bed rangePrinter
Some PA6 (Nylon 6) spools ask for up to 110 °C on the bed; the Creality K1 reaches 100 °C. Set the bed near 90 °C and add a glue stick if corners lift.
Enclosed chamber, exactly what this material wantsPrinter
The Creality K1 is a closed box, so PA6 (Nylon 6) cools slowly and evenly instead of warping.
Keep the spool dryMaterial
PA6 (Nylon 6) soaks up moisture from the air, and damp filament prints rough and stringy. If that happens, dry the spool at 70-90 °C for 12-16 h and store it sealed with desiccant.
Buying the CF version of PA6 (Nylon 6)?
Carbon-fiber filament sands down the Creality K1’s stock nozzle. Plain PA6 (Nylon 6) is fine; for the CF variant, fit a hardened steel nozzle first (a cheap swap).
Safe starting ranges for PA6 (Nylon 6) as a family, not gospel. Each spool below has its exact manufacturer numbers, the dated source, and one-click slicer settings on its page.
