TPE filament offers maximum flexibility with a hardness of 85A (same hardness as NinjaFlex®). It is more flexible than our TPU filament which makes it more suitable for direct drive 3D printers. If your design needs a filament that offers maximum toughness and flexibility, our TPE is the perfect solution.
