Polycarbonate on the Creality K1
Yes, with a couple of cautions. Enclosed and quick. Creality sells the K1C when you want carbon fiber.
Polycarbonate works on the Creality K1, mind a couple of things
Use the lower end of the bed rangePrinter
Some Polycarbonate spools ask for up to 120 °C on the bed; the Creality K1 reaches 100 °C. Set the bed near 100 °C and add a glue stick if corners lift.
Enclosed chamber, exactly what this material wantsPrinter
The Creality K1 is a closed box, so Polycarbonate cools slowly and evenly instead of warping.
Keep the spool dryMaterial
Polycarbonate soaks up moisture from the air, and damp filament prints rough and stringy. If that happens, dry the spool at 80-90 °C for 6-8 h and store it sealed with desiccant.
Buying the CF version of Polycarbonate?
Carbon-fiber filament sands down the Creality K1’s stock nozzle. Plain Polycarbonate is fine; for the CF variant, fit a hardened steel nozzle first (a cheap swap).
Safe starting ranges for Polycarbonate as a family, not gospel. Each spool below has its exact manufacturer numbers, the dated source, and one-click slicer settings on its page.
