Polycarbonate settings for the Creality K1
Great match
These are tuned starting settings for printing Polycarbonate on the Creality K1. The Creality K1 has a direct-drive extruder and an all-metal hotend in an enclosed chamber, so we set the hotend to 275°C and the bed to 100°C. Polycarbonate is one of the strongest filaments but needs high temps and an all-metal hotend.

Recommended Polycarbonate profile
| Hotend temperature | 275°C (tower 260–300°C) |
| Bed temperature | 100°C |
| Print speed | 49 mm/s |
| Retraction | 1.2 mm (direct drive) |
| Part cooling fan | 0% |
| Bed adhesion | Very hot bed + enclosure; PC needs an all-metal hotend. |
| Nozzle | Brass 0.4 mm is fine |
| Difficulty | Advanced |
⚠️ This material prefers a 110°C bed but the Creality K1 tops out at 100°C; use extra adhesion help such as glue stick.
💡 Best uses for Polycarbonate: high-heat parts, impact-resistant parts.

FAQ
- What temperature should I print Polycarbonate on the Creality K1?
- Start at 275°C for the hotend and 100°C for the bed, then run a temperature tower across 260–285°C to dial in your exact filament brand.
- What print speed works for Polycarbonate on this printer?
- Around 49 mm/s is a safe starting point on the Creality K1. This printer can go faster once the profile is tuned, but start conservative for clean walls.
- What retraction should I use?
- Use about 1.2 mm of retraction (direct drive needs very little). If you see stringing with Polycarbonate, raise retraction speed before distance and dry the filament.
- Do I need an enclosure for Polycarbonate on the Creality K1?
- The Creality K1 is enclosed, which is exactly what Polycarbonate needs for warp-free prints.
