Flexible 80A Resin 1 L

RS-F2-FL80-01

Whether you’re optimizing your manufacturing process, rapidly iterating through designs, or assessing form, fit, and function, Formlabs Engineering Resins are formulated to withstand extensive testing and perform under stress. Flexible 80A Resin is the most stiff soft-touch material in our library of Flexible and Elastic Resins, with 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. If you need a less stiff flexible material, try Elastic 50A Resin.  Flexible 80A Resin is a reformulation of Flexible Resin. Flexible 80A Resin offers more advanced mechanical properties and a new look.  Available for Form 3 generation printers, and Form 2.
Supports print resolutions: 100 and 50 microns.
Post-curing required.

Why Choose Flexible 80A Resin?

Create silicone, urethane and rubber-like parts. Produce flexible parts in-house in a matter of hours, replacing outsourcing and molding.


Elastomeric
Leverage bendable parts that return to shape slowly.


Soft and Strong
Stretch and compress parts through repeated cycles without cracking.


Transparent
Create objects that are clear, providing visibility into the model.


Durable
Support user testing with looks and feels like prototypes that can be put to the test.

Applications

Flexible 80A Resin is ideal for hard, flexible prototypes and a great alternative to mold making.

Consider Flexible 80A Resin for:

Handles, grips, and overmolds
Seals, gaskets, and masks
Cushioning, damping, and shock absorption
Cartilage, tendon, and ligament anatomy

Material properties may vary based on part geometry, print orientation, print settings, and temperature. Data was obtained from parts printed on a Form 3 with 100 µm Flexible 80A settings, washed in a Form Wash for 10 minutes, and post-cured at 60°C for 10 minutes in a Form Cure.

Post-Processing

Form Wash Settings

Duration

10 minutes + 10 minutes

Notes

Wash parts printed in Flexible 80A Resin in two cycles, preferably using fresh solvent for the second wash. When washed in TPM, Flexible 80A Resin remains waxy when printed at any layer thickness and requires post-cure. Post-curing removes the waxiness.

Notes

For parts printed in an engineering-focused resin (such as those in the Rigid, Tough & Durable, and Flexible & Elastic families), post-curing ensures that the parts reach their optimal mechanical properties and can function as designed. There is only one recommended post-curing time for Flexible 80A Resin.
