Formlabs® Flexible 80A, V1.1 | Form 4

Formlabs® Flexible 80A Resin, V1.1 is the stiffest soft-touch material in Formlabs' library of Flexible and Elastic Resins. It has an 80A Shore durometer to simulate the flexibility of rubber or TPU. Balancing softness with strength, Flexible 80A Resin can withstand bending, flexing, and compression, even through repeated cycles.

The “80A” in the name represents the material’s Shore durometer. It offers more advanced mechanical properties and a new look.

If you need a less stiff flexible material, try Formlabs Elastic 50A Resin. 

Supports print resolutions: 100 and 50 microns.
Post-curing is required.
