What temperature should I print PETG-CF on the Creality K1C?

Start at 250°C for the hotend and 80°C for the bed, then run a temperature tower across 245–265°C to dial in your exact filament brand.

What print speed works for PETG-CF on this printer?

Around 135 mm/s is a safe starting point on the Creality K1C. It can go faster once the profile is tuned, but start conservative for clean walls.

What retraction should I use?

Use about 1 mm of retraction (direct drive needs very little). If you see stringing, raise retraction speed before distance and dry the filament.

Do I need an enclosure for PETG-CF on the Creality K1C?

An enclosure helps PETG-CF but is not strictly required on the Creality K1C.

PETG-CF settings for the Creality K1C

Great match

⚡ Quick answer: Print PETG-CF on the Creality K1C at 250°C hotend, 80°C bed, 135 mm/s, 40% part-cooling fan and 1 mm retraction. Run a temperature tower to fine-tune your exact spool.

These are tuned starting settings for printing PETG-CF on the Creality K1C. The Creality K1C has a direct-drive extruder with an all-metal hotend, so we set the hotend to 250°C and the bed to 80°C. PETG-CF adds carbon fiber to PETG for extra stiffness and a matte finish.

Troubleshooting PETG-CF on the Creality K1C

Problem	Fix
Stringing or fine hairs	Dry PETG-CF before printing, drop the hotend a few degrees below 250°C, and raise retraction toward 1.4 mm. Damp filament is the No. 1 cause of stringing.
Poor first-layer adhesion	Glue stick as a release agent. Re-level the bed, set a slightly squished first layer, and wipe the sheet with IPA so it is grease-free.
Blobs, zits or rough walls	Slow the outer wall, enable coasting/wipe, and keep retraction near 1 mm. Keep the part-cooling fan low so layers bond and warping stays down.
