Print Quality Profiles
Three presets for common use cases with PC-ABS on the QIDI Q2.
| 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
PC-ABS requires enclosure and high bed temperatures (100-110°C). Use a PEI sheet with glue stick or ABS/PC slurry. A brim is essential for larger parts. Adhesion methods are similar to ABS but warping tendency is moderate.
Temperature Tuning Guide
Nozzle: 265°C
Range: 250-280°C. Printer max: 370°C.
- Poor layer adhesion? Increase +5°C
- Stringing or oozing? Decrease -5°C
- Print a temperature tower to find your exact sweet spot
Bed: 108°C
Range: 100-115°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-ABS on QIDI Q2
Pro Tips for PC-ABS
An enclosure is essential -- PC-ABS warps less than pure PC but more than pure ABS
Print at 250-270°C nozzle and 100-110°C bed for the best results
PC-ABS combines the impact resistance of PC with the printability of ABS -- great for functional parts
Ventilation is important -- PC-ABS emits fumes during printing
Support Settings
For prints requiring supports with PC-ABS, 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.
