TPU and TPE: choosing a flexible filament
Choose flexible filament by the movement you need, its hardness scale, the printed structure and the exact printer and feeder compatibility.
Read the guide →TPU & TPE
Flexible filaments demand attention to hardness, feed path and build-surface release.
Flexible filament is not one stiffness: Shore hardness, printed geometry and wall thickness all matter. Use these guides to understand TPU and TPE grades, reduce feeding problems and check automatic material-system compatibility. Feeder support depends on the precise spool and polymer, not just a label saying flexible.
