Fantastic Flexible Filaments explores a range of springy, stretchable 3D-printing materials that aren’t your run-of-the-mill TPU. From PEBA rebound and Foam TPU Air to glass-fiber-reinforced PBT Pro, polypropylene, super-tough 72D TPU, and the sporty Timemass Active, it rounds up six standout options (complete with links so you can snag them for yourself).
No brand paid to get featured here—some samples were freebies for testing, and the rest are just good finds. If you’re hungry for more 3D-printing wizardry, you can also join the Maker’s Muse community for tips, tricks, and camaraderie.
