PETG-CF settings for the Creality Ender 3 V3 SE
Great match
These are tuned starting settings for printing PETG-CF on the Creality Ender 3 V3 SE. The Creality Ender 3 V3 SE has a direct-drive extruder with a PTFE-lined hotend, so we set the hotend to 240°C and the bed to 80°C. Carbon-fibre PETG combines PETG toughness with extra stiffness and demands a hardened nozzle.

Recommended PETG-CF profile
| Hotend temperature | 240°C (tower 240–260°C) |
| Bed temperature | 80°C |
| Print speed | 45 mm/s |
| Retraction | 1.5 mm (direct drive) |
| Part cooling fan | 40% |
| Bed adhesion | Like PETG; hardened nozzle required. |
| Nozzle | Hardened steel (this filament is abrasive) |
| Difficulty | Advanced |
⚠️ PETG-CF likes up to 260°C, but the Creality Ender 3 V3 SE's PTFE-lined hotend caps it near 240°C — going hotter degrades the PTFE tube and releases fumes.
⚠️ Because the Creality Ender 3 V3 SE is not all-metal, keep the hotend at or below 240°C. For the hottest PETG-CF brands you would need an all-metal hotend upgrade.
💡 Best uses for PETG-CF: rigid functional parts, tooling.
FAQ
- What temperature should I print PETG-CF on the Creality Ender 3 V3 SE?
- Start at 240°C for the hotend and 80°C for the bed, then run a temperature tower across 240–250°C to dial in your exact filament brand.
- What print speed works for PETG-CF on this printer?
- Around 45 mm/s is a safe starting point on the Creality Ender 3 V3 SE.
- What retraction should I use?
- Use about 1.5 mm of retraction (direct drive needs very little). If you see stringing with PETG-CF, raise retraction speed before distance and dry the filament.
- Do I need an enclosure for PETG-CF on the Creality Ender 3 V3 SE?
- No, PETG-CF prints fine in the open on the Creality Ender 3 V3 SE.
