Before You Print
Print Quality Profiles
Three presets for common use cases with CPE on the Bambu Lab X1 Carbon.
| Profile | Layer Height | Speed | Infill | Best For |
|---|---|---|---|---|
| Draft | 0.28mm | 50 mm/s | 10-15% | Rapid prototyping, test fits |
| Standard | 0.20mm | 40 mm/s | 15-20% | General purpose, everyday prints |
| Quality | 0.12mm | 30 mm/s | 20-30% | Miniatures, display pieces, fine detail |
Bed Adhesion
CPE (co-polyester) adheres similarly to PETG. Use a textured PEI sheet at 75-85°C or smooth PEI with glue stick as a release agent. Let the bed cool completely before removing prints.
Temperature Tuning Guide
Nozzle: 255°C
Range: 240-270°C. Printer max: 300°C.
- Poor layer adhesion? Increase +5°C
- Stringing or oozing? Decrease -5°C
- Print a temperature tower to find your exact sweet spot
Bed: 83°C
Range: 75-90°C. Printer max: 120°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
Troubleshooting CPE on Bambu Lab X1 Carbon
Pro Tips for CPE
CPE is Ultimaker's co-polyester; it prints very similarly to PETG
Dry at 70°C for 6-8 hours before printing for best results
Use a textured PEI sheet; CPE can bond too strongly to smooth PEI
CPE is FDA-approved for food contact -- good for food-safe containers
Support Settings
For prints requiring supports with CPE, use tree supports for easier removal and less scarring. Set a 0.15-0.2mm Z-distance between support and model. If you have a dual-extruder setup, consider PVA (for PLA/PETG) or HIPS (for ABS) as dedicated water/solvent-soluble support material.
