Before You Print
Print Quality Profiles
Three presets for common use cases with PLA on the Bambu Lab A1 Mini.
| Profile | Layer Height | Speed | Infill | Best For |
|---|---|---|---|---|
| Draft | 0.28mm | 250 mm/s | 10-15% | Rapid prototyping, test fits |
| Standard | 0.20mm | 175 mm/s | 15-20% | General purpose, everyday prints |
| Quality | 0.12mm | 100 mm/s | 20-30% | Miniatures, display pieces, fine detail |
Bed Adhesion
PLA adheres well to PEI sheets (smooth or textured) without any adhesive. If using a glass bed, apply a thin layer of glue stick or hairspray. Clean the bed with isopropyl alcohol (IPA) before each print for consistent adhesion.
Temperature Tuning Guide
Nozzle: 220°C
Range: 190-220°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: 55°C
Range: 50-60°C. Printer max: 80°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
Troubleshooting PLA on Bambu Lab A1 Mini
Pro Tips for PLA
Print a temperature tower to find the sweet spot for your specific PLA brand
Store filament in an airtight container with desiccant when not in use
Clean the bed with IPA before every print for consistent adhesion
Use 100% cooling fan from layer 2 onward for best overhangs and bridging
PLA is great for prototyping but avoid leaving prints in hot cars or direct sunlight
Support Settings
For prints requiring supports with PLA, 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.
