Printing Tips
- Storage: Store in the provided moisture-resistant aluminum bags when not in use. For prolonged storage, using a dry box with desiccant, maintaining humidity below 15% is ideal.
- Drying: If moisture absorption is suspected, dry the filament at 50 - 60°C for 4 - 6 hours in a filament dryer. Find filament dryers here.
- Printing: Ensure a clean, level print bed. Printing with a bed temperature of 20 - 50°C is recommended, adjusting to your printer's settings. For ideal extrusion temperatures, use a range of 200 - 225°C.
- Note: The black variant performs better at slightly cooler extrusion temperatures compared to the white variant.
- Troubleshooting:
- Stringing: Try adjusting retraction settings and lowering print speeds. Additionally, ensure the filament's moisture level is within acceptable limits.
- Poor Bed Adhesion: Consider using a glue stick or slightly increasing the bed temperature to improve adhesion.
