USE & APPLICATIONS OF SMARTFIL FLEXIBLE 93A TPU:

If you're looking to print flexible parts, this is your filament. The most common 3D printed applications include:

• Footwear
• Automotive parts
• RC components
• Handles and grips

Smartfil Flexible is an elastic TPU-based filament with high resistance to hydrolysis and oxidation. Its Shore A hardness of 93 makes it compatible with most 3D printers. If your printer uses a Bowden extrusion system, verify it can handle flexible materials, as pushing soft filament through the tube can be challenging. Keep in mind:

• Shore A hardness is used for soft elastomers
• Shore D hardness is used for rigid plastics
• A higher Shore value indicates a stiffer material

MANUFACTURER RECOMMENDATIONS:

This material is moisture-sensitive. Store it sealed in a cool, dry place to maintain quality.

1. Ensure consistent flow: Printing TPU isn't easy at first. Adjust print settings gradually. Use adhesive spray or glue stick for better bed adhesion.
2. Set the right temperature: Each printer is different. Start at 225 °C. Higher temps reduce clogging, but excessive heat may cause poor surface finish.
3. Low print speed: Unlike PLA or ABS, TPU should not be printed fast. 35 mm/s is ideal for consistency.
4. Layer height: Use 0.2 mm for a good balance of detail and strength.
5. Disable retractions if using Bowden extruder to avoid clogs.
