Material Selection Guide

Consider These Factors:

1. Application Requirements

   • Strength needed
   • Flexibility requirements
   • Chemical resistance
   • Temperature resistance

2. Printing Difficulty

   • Your skill level
   • Printer capabilities
   • Required bed temperature
   • Warping tendency

3. Post-Processing

   • Sanding requirements
   • Support removal
   • Surface finishing options

Storage and Handling

Proper Storage:

• Keep filaments in sealed containers
• Use desiccant packs to absorb moisture
• Store at room temperature
• Avoid direct sunlight

Signs of Moisture Damage:

• Brittle filament
• Popping sounds during printing
• Poor layer adhesion
• Stringing and oozing

Troubleshooting Common Issues

Poor Layer Adhesion

• Check nozzle temperature
• Adjust printing speed
• Verify bed leveling

Warping

• Use heated bed
• Apply adhesion aids
• Reduce cooling fan speed
• Use enclosure for ABS
