NinjaFlex’s unique flexibility and smooth feeding characteristics enable you to create in ways you never thought possible. Open a world of possibilities, limited only by your imagination. NinjaFlex, a cutting-edge filament for 3D printers, is a specially formulated thermoplastic elastomer (TPE) that produces flexible prints with elastic properties.
The filament is very flexible (I can tie a tight knot on it without it breaking) The filament is also elastic but not as much a a regular rubber band, perhaps 5-8 times harder if I should make a guess.
