Buying Guide

Match shore hardness to application

Softer TPUs (lower Shore A) compress more for sealing and cushioning; firmer blends (higher Shore A) resist deformation for functional hinges and mounts

Check diameter tolerance and spool weight

Consistent 1.75 mm tolerance and 1 kg spool sizes simplify feed reliability and allow predictable material planning for small to medium runs

Prioritize print settings for flexible filaments

Use slower speeds, reduced retraction, and direct-drive or guided Bowden setups to reduce jams and stringing when printing TPU

Consider high-speed TPU for production

Specialized ‘high speed’ TPU formulations enable faster layer times with less deformation, useful when throughput matters

Evaluate surface finish and color options

Color variants and formulation differences affect visible layer lines and post-processing; pick a filament that balances appearance and mechanical needs
