Suggested Print Settings

• Print Temperature (°C) – 210 to 230

• Bed Temperature (°C) – 25 to 60 (heated bed recommended for adhesion)

• Print Speed (mm/s) – 20 to 30 (slow speeds required for flexible materials)

• Travel Speed (mm/s) – 60 to 80

• Nozzle Diameter – ≥0.4mm recommended

• Cooling Fan – Low or off (to improve layer bonding)

• Enclosure – Not required, but helps with consistent results

Key Features

• Ultra‑flexible filament with soft, skin‑friendly feel

• Superior elasticity compared to TPU‑95A and eFlex

• High wear and tear resistance

• UV, cold, and heat resistance for outdoor applications

• Stable dimensional tolerance – low warping, smooth feeding, minimal stringing

• Matte surface finish with strong layer adhesion

Applications

• Shoe soles and insoles

• Watch straps and phone cases

• Drone parts requiring shock absorption

• Flexible joints and seals

• Sporting goods and protective gear

• Conveying pipelines and industrial components

Packaging

• Supplied on 1kg spool

• Vacuum‑sealed with desiccant for moisture protection

• Compatible with most FDM printers capable of handling flexible filaments

This filament is best suited for users who need durable, elastic parts that can withstand bending, stretching, and impact without breaking. It requires careful handling during printing (slow speeds, direct‑drive extruder preferred).
