Fantastic Flexible Filaments (which AREN’T TPU)

A quick rundown of some springy, stretchy 3D-printing filaments that aren’t your average TPU:

• PEBA (95A), Foam TPU Air, and a GF-reinforced PBT Pro for added strength
• Polypropylene (PP) options and a beefier 72D TPU for tougher parts
• Timemass Active for dynamic, high-performance prints

All links include a handy 3D-printing eBook, plus affiliate disclosures—no paid placements here—and some gear was kindly sent free for testing. Don’t forget to join the Maker’s Muse community for more tips!
