USES AND APPLICATIONS – TPU GLOW IN THE DARK FILAMENT:

If you're looking to print flexible parts, this is your filament. Common 3D-printed objects made with this material include:

• Footwear
• Automotive components
• RC parts
• Grips and handles

Smartfil Flexible is an elastic filament made of polyurethane, offering high resistance to hydrolysis and oxidation.
Thanks to its 93 Shore A hardness, it's compatible with most desktop 3D printers. If you're using a Bowden extrusion system, make sure your printer supports flexible filaments, as they are harder to push through the tube.

Note that Shore A hardness applies to soft elastomers, while Shore D is used for harder plastics. The higher the number, the higher the hardness.

MANUFACTURER'S PRINTING RECOMMENDATIONS:

This filament is hygroscopic and should be stored sealed in a cool, dry place for optimal performance.

1. Ensure continuous flow: Printing TPU is tricky at first. Adjust settings until you achieve consistent extrusion. Use hairspray or adhesive spray for bed adhesion.
2. Use the correct temperature: Every printer behaves differently. Start at 225 °C. Higher temps help prevent clogs, but excessive heat may affect part quality.
3. Use low printing speed: TPU isn’t meant for high-speed printing like PLA or ABS. Stick to 35 mm/s for clean results.
4. Layer height: 0.2 mm for a good balance between detail and speed.
5. Disable retractions if you're using a Bowden extruder to avoid clogging issues.
