Recommendations#
Storage#
- Store filament in airtight containers with desiccant
- Keep away from humidity and direct sunlight
- Some filaments (Nylon, TPU) require active drying before printing
Printer Setup#
- Use appropriate bed adhesion methods (PEI, glue stick, etc.)
- Consider enclosure for temperature-sensitive materials (ABS, Nylon)
- Adjust cooling fans based on material requirements
Print Settings#
- Layer Height: 0.1-0.3mm depending on detail requirements
- Print Speed: Reduce for challenging materials
- Retraction: Adjust based on material stringing characteristics
- First Layer: Slower speed and higher temperature for better adhesion
Specialty Filaments#
Carbon Fiber Reinforced#
- Properties: Increased stiffness, dimensional stability
- Considerations: Abrasive to nozzles, requires hardened components
Wood-Filled#
- Properties: Wood-like appearance and feel
- Considerations: Variable temperature printing for different “burn” effects
Metal-Filled#
- Properties: Metallic appearance, increased weight
- Considerations: Highly abrasive, can be polished for metallic finish
Troubleshooting#
Stringing#
- Increase retraction distance
- Lower printing temperature
- Adjust travel speed
Warping#
- Increase bed temperature
- Use enclosure for high-temperature materials
- Apply proper bed adhesion techniques
Moisture Issues#
- Dry filament before printing
- Store properly
- Consider filament dryer for hygroscopic materials
