Ninjaflex® Flexible TPU Filament

The Industry Leading Flexible Filament

NinjaFlex® flexible filament leads the industry thanks to its superior flexibility and longevity compared to non-polyurethane materials.

Made from a specially formulated thermoplastic polyurethane (TPU) material, this patented technology boasts a low-tack, easy-to-feed texture. The result is uniquely flexible, strong prints ideal for direct-drive extruders.
