Best TPU Filament for Flexible, Grippy Prints (2026)
Updated How we research
SUNLU TPU Filament 1.75mm, 1kg Black, 95A High Speed Flexible, +/- 0.03mm
SUNLU TPU in black, a 95A high speed flexible 1.75mm filament on a 1kg spool with +/- 0.03mm tolerance.
OVERTURE High Speed TPU 95A Flexible Filament 1.75mm, 1kg Black
OVERTURE High Speed TPU 95A in black, a flexible 1.75mm filament on a 1kg spool for quicker flexible prints.
TPU is a flexible filament, and its shore hardness tells you how soft or firm the result will be, with lower numbers meaning stretchier parts. Check that rating first, then look at diameter consistency, since flexible filament is more sensitive to feeding problems and jams. A direct-drive extruder handles TPU far better than Bowden setups, and slower print speeds improve reliability. Good moisture packaging matters, because damp TPU bubbles and prints rough. TPU suits phone cases, gaskets, seals, grips, and any part that needs to bend or absorb shock. It is durable and abrasion resistant once dialed in. A practical tip: print slowly and reduce retraction to avoid jams in the extruder, and pick a shore hardness that matches the job, since a firmer TPU is far easier to print for a first attempt than the softest, stretchiest grades that tangle in the feed path.
