FAQ

Do you have any suggestions when printing TPU90 with support structure on single extruder printer?

Generally, when printing with TPU materials, if support structures are needed, we recommend using specialized support materials such as PolyDissolve™ S1. However, considering the single extruder devices that users may have, we suggest customers adjust the orientation of the model to minimize the use of support structures, or place support structures in inconspicuous areas that won't affect the appearance.

Can my printer print PolyFlex™ TPU90?

We highly recommend to use a direct drive printer to print PolyFlex™ TPU90. A direct drive printer is a printer with the extruder mounted on top of the hot end.

What makes PolyFlex™ TPU90 unique?

PolyFlex™ TPU90 is easier to print than similar flexible material thank to its high melt index.
