frequently asked questions

What is TPU 90A Powder used for?

Formlabs TPU 90A is ideal for flexible, durable parts such as seals, gaskets, wearables, vibration dampers, and cushioning components. It combines elasticity and strength for both prototyping and end-use production.

How flexible is TPU 90A?

With a Shore hardness of 90A and elongation at break up to 310%, it behaves like a tough rubber—flexible enough to bend and compress, yet strong enough to resist tearing.

Can I reuse TPU 90A powder?

Yes. TPU 90A Powder has a low refresh rate of 20%, meaning up to 80% recycled powder can be reused while maintaining consistent mechanical performance.

Which printers are compatible with TPU 90A?

This material is designed for the Formlabs Fuse 1 and Fuse 1+ 30W selective laser sintering (SLS) printers, ensuring reliable print quality and easy post-processing.

Is TPU 90A suitable for functional parts or just prototypes?

It’s fully capable of end-use production, not just prototyping. TPU 90A parts are durable, flexible, and wear-resistant—ideal for demanding, real-world applications.
