Special Considerations by Filament Type
Glow-in-the-Dark Filaments
- Key Issue: Phosphorescent particles are not moisture-sensitive but may lose luminescence if exposed to contaminants.
- Solution: Keep filaments sealed and clean, and avoid storing them with abrasive materials.
Wood Filaments
- Key Issue: Wood fibers can absorb moisture, leading to bubbling during extrusion.
- Solution: Store in airtight containers with fresh desiccant packs to keep the filament dry.
Metal-Infused Filaments
- Key Issue: Metal particles can settle unevenly, affecting extrusion consistency.
- Solution: Shake or rotate the spool occasionally to redistribute particles evenly.
Carbon Fiber Filaments
- Key Issue: Moisture absorption can weaken layer bonding and structural integrity.
- Solution: Use a filament dry box or bake the filament at low temperatures to remove moisture.
Marble Filaments
- Key Issue: Marble textures can become inconsistent if exposed to contaminants or moisture.
- Solution: Ensure filament is stored in clean, dry conditions with minimal air exposure.
Tips for Handling Exotic Filaments During Printing
- Inspect for Damage: Before using exotic filaments, check for signs of brittleness, uneven texture, or moisture absorption.
- Prevent Tangling: Many exotic filaments, like wood or metal-infused options, can be more prone to spooling issues. Unspool them carefully to avoid tangles.
