This roundup dives into a handful of sneaky soft 3D-printing materials beyond your standard TPU—think PEBA elastic filament, foam-style TPU Air, glass-filled PBT, polypropylene, 72D TPU and Timemass Active. Each entry comes with a handy link to snag a spool (some are affiliate links, FYI).
No company paid to play—some samples were gifted, but reviews are honest. If you’re thirsty for more filament tips, you can also join the Maker’s Muse Community for extra projects and advice.
