TPU Printing Guide

Printing setup

TPU requires slower speed and a controlled feeding path.

Direct drive extruders usually handle flexible filament more easily than long Bowden paths.

• Reduce print speed for stable extrusion.
• Avoid excessive retraction.
• Dry TPU if the surface becomes rough or bubbly.

Applications

TPU can be used for phone cases, soft pads, flexible hinges, protective feet, seals and model accessories.

It is a useful specialty product for resellers targeting functional users.

Wholesale buyer notes

Evaluate TPU with real flexible models, not only small test cubes.

Confirm hardness, color and packaging before launching a marketplace listing.
