TPU-95A Matte Filament – Flexible, Low-Gloss Finish, 1.75mm, 1kg

Shore A measures resistance to indentation — the lower the number, the softer the material. At 95A this is the firmest TPU we stock, and the easiest to print: flexible and impact-absorbing, but stiff enough to feed reliably on most printers. It's the grade to start with if you've never printed a flexible filament. TPU Shore hardness explained: 70A vs. 80A vs. 85A vs. 90A vs. 95A explains how the Glossy, Matte, and Foam finishes change the print too.

Yes — TPU is hygroscopic and picks up moisture faster than most filaments. Dry it as soon as you hear popping or see bubbles, heavy stringing, weak layers, or a rough surface, and print from dry storage whenever you can. How to dry filament at home compares ovens, dry boxes, and dedicated dryers; how to store filament properly covers keeping it dry between prints.

Direct drive is recommended. A short, constrained filament path with very low spool resistance gives the most reliable feeding — a long Bowden tube lets flexible filament buckle instead of pushing forward. This grade is firm enough that a well-tuned Bowden setup can work, but direct drive removes most of the trouble. Our AMS and multi-material setup guide covers feed-path length in more detail.

Moisture is the usual culprit. Dry the filament first — how to dry filament at home covers the options — then lower the nozzle temperature or adjust retraction carefully and keep travel moves efficient. TPU needs a different retraction approach from rigid filaments, which our step-by-step retraction tuning guide covers material by material.

It depends on your printer and feeder. Flexible TPU can buckle or jam in the long feed paths these systems use, so run it from an external spool with a direct feed unless your equipment manufacturer explicitly supports this hardness. Our AMS and multi-material setup walkthrough covers what to check before loading a flexible spool.

Print slowly, calibrate flow, limit acceleration, keep the filament dry, and avoid building excessive pressure at the nozzle. Always test a small calibration part before committing to a production run — what a calibration print tells you explains how to read the result rather than just eyeballing it.
