Before You Print
Print Quality Profiles
Three presets for common use cases with PC on the Bambu Lab X1 Carbon.
| Profile | Layer Height | Speed | Infill | Best For |
|---|---|---|---|---|
| Draft | 0.28mm | 40 mm/s | 10-15% | Rapid prototyping, test fits |
| Standard | 0.20mm | 30 mm/s | 15-20% | General purpose, everyday prints |
| Quality | 0.12mm | 20 mm/s | 20-30% | Miniatures, display pieces, fine detail |
Bed Adhesion
Polycarbonate needs very high bed temperatures and excellent adhesion. Use a PEI sheet at maximum bed temperature. Apply glue stick as a release agent (PC can bond too strongly). A brim is essential. Consider Magigoo PC specialty adhesive for best results.
Temperature Tuning Guide
Nozzle: 285°C
Range: 260-310°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: 110°C
Range: 100-120°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 PC on Bambu Lab X1 Carbon
Pro Tips for PC
PC is the most demanding common filament to print -- make sure your setup is fully prepared
An all-metal hotend is mandatory; PTFE-lined hotends will degrade at PC temperatures
Seal your enclosure as thoroughly as possible for the best results
Use glue stick as a release agent -- PC can bond so strongly to PEI that it damages the sheet
If you are new to high-temp printing, try ABS or ASA first before attempting polycarbonate
Support Settings
For prints requiring supports with PC, 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.
