This Maker’s Muse roundup spotlights six awesome flexible filaments that aren’t your run-of-the-mill TPU: PEBA rebound, airy Foam TPU Air, glass-fiber-reinforced PBT Pro, polypropylene, a beefy 72D TPU, and the sporty Timemass Active. Plus there’s a handy 3D Printing eBook link to dive deeper, and yep, some of those are affiliate links to snag your own spools.
No hidden sponsors here—products were tested and reviewed without paid placements (though a few freebies landed for testing). If you’re hungry for more tips, join the Maker’s Muse community and keep the 3D printing conversation going!
