What this spool is and who uses it

This is a 1 kg spool of black TPU filament with a 1.75 mm diameter, designed for FDM 3D printers. The material carries a 95A hardness rating and delivers 800% elongation at break, making it suitable for flexible parts such as watch bands, insoles, phone cases and keyrings.

Who this suits and who should look elsewhere

Makers who need a flexible filament that rebounds to its original shape after repeated bending will find this TPU works well with direct-drive and Bowden extruders on printers such as Ender 3, Prusa and Voron. Users whose printer hardware cannot reliably feed soft, elastic materials or who require a rigid structural plastic should choose a different material.

The specification that decides fit

Dimensional accuracy is held to ± 0.05 mm, and the spool is precision-wound to prevent tangling and ensure consistent feeding. If your printer’s extruder path or filament sensor cannot handle this tolerance window, the filament will not print reliably.

Questions about this item

How does the 95A hardness feel on a finished print?

The 95A shore hardness gives a rubber-like feel that bends easily but snaps back to its original shape, so items such as watch bands or phone cases survive repeated flexing without staying bent.

What does the ±0.05 mm diameter tolerance mean for my extruder?

The tight tolerance keeps the filament round and consistent, letting direct-drive and Bowden extruders push it smoothly at high flow rates without grinding or jamming.

Will the 1 kg spool fit on my printer’s standard holder?

The spool weighs 1 kg (2.2 lbs) and is precision-wound for good roundness, so it sits on most common filament mounts without wobble or tangling.
