NinjaFlex Flexible 3D Printer Filament 

NinjaFlex® flexible filament is an industry leader because of its superior flexibility and longevity compared to non-polyurethane materials. It’s made from a specially formulated thermoplastic polyurethane (TPU) material which boasts a low-tack, easy-to-feed texture. Its consistency in diameter and ovality (roundness) distinguishes it from other polyurethane materials. The unique flexibility of this material makes it ideal for direct drive extruders. All NinjaFlex filaments are made in the USA. NinjaFlex is patent-pending technology.
