Hello3D TPU Filament

Hello3D TPU Flexible Filament

Hello3D TPU Flexible filament is a durable, rubber-like 3D printing material designed for parts that need flexibility, toughness, and impact resistance. TPU is a great choice when standard rigid materials like PLA are too stiff and you need a printed part that can bend, compress, or absorb vibration.

This flexible filament is ideal for protective feet, bumpers, grips, gaskets, seals, vibration-dampening pads, phone cases, flexible brackets, tool holders, tires, straps, and other functional parts that need a combination of strength and flexibility.

Made from virgin raw material, Hello3D TPU is formulated for smooth feeding, consistent extrusion, and dependable print quality. Hello3D filament is produced using 100% new raw material and is manufactured under ISO9001 quality standards. It is also RoHS compliant.

Printing Tips

TPU prints best at slower speeds with a smooth, well-supported filament path. If you experience feeding issues, reduce print speed, lower retraction distance, and make sure the filament path between the extruder and hotend is as constrained as possible.

For best results, dry the filament before printing and store it sealed when not in use. Flexible materials can absorb moisture from the air, which may cause stringing, popping, inconsistent extrusion, rough surface finish, or weaker layer bonding.

Start with a generic TPU profile if available, then tune temperature, speed, retraction, and cooling for your printer. Direct-drive extruders are usually easier for TPU, while Bowden setups may require slower speeds and extra tuning.
