Here’s a quick roundup of cool non-TPU flexibles for your 3D printer: PEBA (super bouncy, 95A), Foam TPU Air for lightweight prints, PBT Pro (GF) for tougher parts, polypropylene for chemical resistance, a beefed-up 72D TPU, plus the sporty Timemass Active. There’s also a handy 3D printing eBook link and a shout-out to the Maker’s Muse community.
Heads up: some links are affiliate, and a few samples were freebies—but nobody paid to play. Just real talk on flexible filament options beyond plain old TPU.
