Features

Firm flexible for footwear and structural parts

A firmer TPU that still deforms under force and recovers its shape. Prints at higher speeds and holds structure better, which makes it the grade for shoe midsoles and lattice structures.

Best for

  • Shoe midsoles
  • Lattice cushioning
  • Belts and pulleys
  • Impact guards

Frequently asked questions

How fast can I print 98A?
On a direct-drive printer 60–100 mm/s is realistic. It behaves closer to a rigid filament than 95A does.
What does 98A mean?
Shore A hardness. 98A is close to a hard rubber tyre tread: it flexes in thin sections and stays firm in thick ones.
Do I need to dry it before printing?
Every spool ships vacuum-sealed with desiccant. If the bag has been open for more than a few days, or you see popping and stringing, dry at the temperature on the spec grid before printing.
