Frequently Asked Questions

What are the optimal drying settings for PolyFlex TPU 90?

It is recommended to dry PolyFlex TPU 90 filament at 70°C for a minimum of 8 hours before printing. Proper drying prevents common flexible filament issues like stringing, poor layer adhesion, and inconsistent extrusion, ensuring optimal print quality and mechanical properties for your flexible parts.

What print speed range is best for PolyFlex TPU 90?

PolyFlex TPU 90 performs well with printing speeds between 30-70 mm/s. Slower speeds typically offer higher detail and better control, especially for intricate flexible parts. Higher speeds can be used for simpler geometries, but always monitor for extrusion issues or skipped steps due to material flexibility.

What build plate temperature and adhesion methods are recommended?

A build plate temperature between 25-60°C is recommended for PolyFlex TPU 90. For reliable bed adhesion, surfaces like blue painter's tape, PEI sheets, or a thin layer of PVA glue can be effective. Ensure the first layer is printed slowly with slight compression for strong bonding and to prevent warping.
